Wondabyne Alt = 12 m
Wondabyne is situated in Brisbane Waters National Park on the banks of Mullet River, which feeds into the Hawkesbury River north of Brooklyn. The area is defined by the National Park's flora and fauna, the quarry, railway station and a few houses sitting above the water around the river. The quarry produced sandstone building materials, used in the construction of the National War Memorial in Canberra. More recently, in 2000, the quarry was re-opened for restoration of St Mary's Cathedral spire in Sydney. Wondabyne Station, named after the nearby Mt Wondabyne, was built in 1889 and exclusively used for the quarry - it was then known as Mullet Creek Station. The station is one of the smallest on the line and one of very few railway stations in a NSW National Park. When you catch the train to Wondabyne, let the guard know you want to get off at Wondabyne Station, otherwise the train will not stop. Travel in the last carriage as the platform is very short. To catch the train from Wondabyne, wave to the driver.

(0 km) Wondabyne Station to Eastern end of the Pindar Cave Track
Track: Hard - bushtrack,servicetrail
Length = 1.47 km Time = 32 mins
Climb = 172 m Descent = -18 m
From the north-bound platform of Wondabyne Station, this walk follows the 'The Great North Walk' sign[1] off the southern the end of the platform[2], keeping the train lines (and water) to your left. The track soon leads past a strangler fig[3] and a large boulder[4] then bends right and heads up a timber staircase[5] with a metal landing at the top. The track winds steeply uphill, up a series of timber[6] and rock steps[7] for just over 200m to pass a filtered view of the cranes[8] (right), down at the old Gosford Quarry. Here the walk continues a bit more steeply uphill for another 150m, up a series of rock steps[9], and then, soon after passing up the carved steps in a cleft in a rock[10], the track flattens out[11] and comes to a clearing at the end of a management trail[12], marked with a 'Brisbane Water National Park' sign[13].
Continue straight: From the clearing[14], this walk follows the wide management trail uphill past the 'Brisbane Water National Park' sign[15]. The trail leads up quite steeply[16] for about 250m, where the trail bends right then leads gently uphill[17] for about 600m. Here the trail leads up a short but quite steep hill[18], to then bend left and, about 150m later, come to an intersection with the Pindar Cave track (that leads over a rock platform[19], on your left), marked with a GNW arrow post[20] (on your right).

Track: Moderate - servicetrail
Length = 629 m Time = 11 mins
Climb = 19 m Descent = -5 m
Continue straight: From the intersection[21], this walk follows the GNW arrow post[22] north, gently uphill along the wide trail. The trail gently undulates along the top of the ridge for about 600m to come to an intersection with the 'Great North Walk' track (on your right), marked with a 'Wondabyne Station' sign[23] pointing back down the hill.

(2.1 km) Int of GNW and Wondabyne trail to Int of GNW and Gosford Rifle Range trail
Track: Moderate - servicetrail
Length = 1.12 km Time = 22 mins
Climb = 27 m Descent = -40 m
Continue straight: From the intersection, this walk follows the 'Girrakool' sign[24] uphill along the wide trail. After about 50m, this trail leads up onto a large rock platform[25]. From the top of this platform, there are some distant views over Mooney Mooney Creek[26]. The walk continues on the platform, following the scrape marks on the rock, tending right, to soon find the wide trail again[27]. The trail undulates (moderately steeply in a few places) along the ridge line for about 900m to come to an intersection marked with a 'Girrakool' sign (pointing left), just before a 'No Entry Past This Point' sign[28].

(3.23 km) South end of Scopas Peak Track to Scopas Peak
Track: Hard - bushtrack
Length = 1.17 km Time = 23 mins
Climb = 80 m Descent = -14 m
Turn left: From the intersection, this walk follows the 'Girrakool' sign[29] and GNW arrow post north along the clear track. After about 150m, the walk comes to a green painted metal box on a post (on your right), containing a Great North Walk intentions book[30].
Continue straight: From the Great North Walk intentions book[31], after leaving your comments, this walk heads north, gently up along the clear track[32]. The track gently undulates along this ridge for about 750m, leading across a long sandy saddle[33] to the base of Scopas Peak. Here the walk climbs steeply for about 230m, stopping occasionally to enjoy the view, up the series of rocks with cut steps[34] and past a few rock walls[35]. Near the top of this climb, the track bends left to lead up to a view point just to the west of Scopas Peak[36].

(4.39 km) Scopas Peak to Tributary Crossing
Track: Hard - bushtrack
Length = 2.42 km Time = 57 mins
Climb = 33 m Descent = -189 m
Veer right: From the view point[37] just west of Scopas Peak, this walk heads north-east and gently downhill[38], initially keeping the distant views to your left. The track leads down, becoming notably steeper[39] for about 300m to then cross over a long rock platform[40], with a series of GNW arrow posts[41] guiding the way. After this rock platform, the track leads for another 250m, crossing a couple of small rock platforms[42] before leading along a heathy track[43]. About 400m along, the walk passes another view to Mooney Mooney Bridge[44], then comes to the edge of another large rock platform[45]. A series of GNW arrow posts[46] lead across this rock platform, generally heading away from Scopas Peak[47] for about 400m, where the arrows lead off the rock platform and back onto a heathy track[48]. The rocky track continues down along the ridge[49] for just shy of 300m to come to the edge of another smaller rock platform with more with distant views[50]. From here, the track leads downhill for about 600m, passing a couple of rocky outcrops[51] and becoming progressively steeper until coming to the edge of an intermittent creek, which flows over the solid sandstone platform[52], at the bottom of the valley.

(6.81 km) Tributary Crossing to Phil Houghton Bridge
Track: Hard - bushtrack
Length = 938 m Time = 30 mins
Climb = 65 m Descent = -129 m
Continue straight: From the western bank, this walk crosses the intermittent creek which flows over the solid sandstone platform[53], to follow the track uphill. The rocky track initially leads gently uphill[54] but soon leads steeply up[55] for about 130m, where the track mostly flattens out to pass a sandstone overhang[56] (on your right). Soon after this overhang, the track leads over a small gully[57] then along the side of a longer rock wall[58] with another tall sandstone overhang[59]. The track continues gently downhill[60] for another 300m, becoming a little steeper along the way, until just past a set of rock steps. Here the track begins to head steeply down the side of the hill for about 130m, first passing through a cleft in the rock[61] then past a few rock walls. Just after a few switchbacks, this walk heads into a narrow gully, past a small 'Patonga' sign, then comes to a three-way intersection beside an intermittent creek[62], marked with a large 'The Great North Walk' sign with a 'Patonga Ferry' arrow[63] pointing back up the hill.
Continue straight: From the intersection, this walk follows the 'Piles Creek' sign[64] down the track (keeping the valley to the right). The rocky track heads steeply downhill[65] for about 170m to Piles Creek[66]. Just past the old bridge[67], this walk climbs up the stairs[68] to cross the Phil Houghton suspension footbridge[69], enjoying the views of the tidal Piles Creek[70]. On the other side, this walk climbs down the stairs[71] to an intersection[72] beside a large clearing[73] (and campsite, on your left).

Phil Houghton Bridge Alt = 3 m
The Phil Houghton Bridge is a metal suspension bridge that crosses Piles Creek. It is part of the Great North Walk and replaces an older bridge, with part still visible upstream. The bridge can hold up to 8 people and feels very stable. There are great views both up and downstream half way across this bridge. There is a clearing on the northern side that people have used for camping.

(7.75 km) Phil Houghton Bridge to Brisbane Water NP sign
Track: Moderate - bushtrack
Length = 1.79 km Time = 36 mins
Climb = 62 m Descent = -66 m
Turn left: From the intersection on the northern end of the 'Phil Houghton Bridge', this walk follows the 'Mooney Creek' arrow[74] through the large clearing and campsite[75], keeping Piles Creek to your left[76]. The track leads under a large dead tree[77] then winds past some cliffs[78] and among large boulders[79] for about 1km then crosses a short timber bridge with handrails[80]. Just past this bridge, this walk heads over a short flat timber bridge[81], then about just shy of 150m later, heads along a section of timber boardwalk[82]. From this tall eucalypt forest, this track contours around the side of the hill for about 500m, alongside Piles Creek[83], then starts to climb passing among the grass trees[84] before heading down a handful of timber steps and coming to a three-way intersection marked with a 'Brisbane Waters National Park' sign[85], just before Mooney Mooney Creek.

(9.54 km) Brisbane Water NP sign to Mooney Mooney Creek Trackhead
Track: Moderate - bushtrack
Length = 535 m Time = 11 mins
Climb = 26 m Descent = -2 m
Turn right: From the intersection, this walk follows the GNW arrow post[86] directly away from the face of the 'Brisbane Waters National Park' sign[87] along the clear track[88], keeping Mooney Mooney Creek to your left. After about 100m, this walk crosses a green timber footbridge[89], then about 200m later comes to a small clearing and intersection just before the road bridge[90]. Here the walk turns right, following the old management trail uphill through the tall forest[91] for about 200m then heading around a locked gate[92]. Just past the gate, this walk turn left and heads up the short steep bank[93] to come to a T-intersection with the old Pacific Hwy, at a large gravel car park[94] marked with 'Mooney Mooney Creek' Trackhead[95] (just east of the Mooney Mooney Creek bridge).

(10.07 km) Mooney Mooney Creek Trackhead to National Park Gate
Walk: Easy - road
Length = 1.5 km Time = 27 mins
Climb = 31 m Descent = -53 m
Turn left: From the intersection, this walk follows the 'Newcastle' sign[96] along the narrowing gravel verge[97], keeping the Old Pacific Hwy just to your right. After about 200m, this walk comes to then crosses the concrete road bridge[98] over Mooney Mooney Creek, enjoying the view of the wide creek[99] below. Once on the other side, this walk heads past a detailed 'Risk Warning'[100] sign suggesting you be sensible as you cross the bridge (hope it is not too late) to then come to an intersection with Karool Rd[101], just on the other side of the highway (on your right).
Turn right: From the intersection[102], this walk follows the gravel 'Karool Road'[103] gently downhill, keeping Mooney Mooney Creek to your right[104]. This road leads past a few homes for about 600m to then pass a notable houseboat house[105]. About 250m past this house, this walk come to a Y-intersection[106], marked with a 'The Great North Walk' sign[107], just before the tall concrete Mooney Mooney Bridge[108].
Veer left: From the 'Y' intersection[109], this walk follows the 'The Great North Walk' sign[110] along the upper dirt road to pass under the Mooney Mooney (F3 freeway) Bridge[111]. Just over 250m after passing under the tall bridge, this walk leads up to a large turning area[112] just before the locked gate[113], marked with a 'Brisbane Water National Park' sign[114].

(11.57 km) National Park Gate to Mooney Mooney Creek Campsite (south)
Track: Moderate - servicetrail
Length = 601 m Time = 13 mins
Climb = 25 m Descent = -25 m
Continue straight: From the end of the dirt road[115] (that branches of Karool Rd, just north of the Mooney Mooney Bridge), this walk heads uphill along the trail and around the locked gate[116] next to the timber 'Brisbane Water National Park' sign[117]. The trail leads uphill for about 200m to where the trail bends left to pass over the crest of the hill (passing a faint track on your left[118]). Here the trail leads down the other side, still keeping Mooney Mooney Creek to your right[119] for another 400m to come to an intersection marked with a GNW arrow post[120], beside a large grassy clearing[121] and campsite (on your right).

Mooney Mooney Creek Campsite (south) Alt = 4 m
This is clearing is beside the wide Mooney Mooney Creek and provides a large flat area to pitch a few tents. There are some high tension power lines nearby and you can hear the hum of the F3 from here, so it is not the most remote campsite. There are no facilities or water (the creek is salty). All that said it is still a pleasant spot beside the wide creek to rest for a while or for the night.

(12.17 km) Mooney Mooney Creek Campsite (south) to Mooney Mooney Creek Campsite (north)
Track: Moderate - bushtrack,servicetrail
Length = 1.32 km Time = 24 mins
Climb = 29 m Descent = -28 m
Veer right: From the intersection[122] just above the campsite, this walk follows the GNW arrow post[123] down along the track, keeping the clearing and campsite[124] to the right. The track soon leads over a small flat timber bridge[125] then over the next 60m, the track heads under the high tension power lines (past the caution sign[126]) and then along a short section of timber boardwalk[127]. About 20m later, this walk veers right at a Y-intersection[128], then continues along the mostly flat track beside Mooney Mooney Creek for about 300m, to cross a small rocky tidal creek[129]. The track then continues through the tall forest[130] beside Mooney Mooney Creek for about 600m, passing a couple of she-oak stands[131] before the track then bends left and comes to an indistinct intersection[132] beside a timber and metal footbridge[133].
Continue straight: From the intersection, this walk cross the timber and metal footbridge[134] over a tidal, unnamed creek[135] to then turn right and follow the track which soon bends left. Keeping Mooney Mooney Creek to the right[136], this track passes a small cliff[137] then follows the mostly flat track through the tall forest[138] for about 170m to come to a large clearing with tall blue gums[139] and a metal fireplace[140] (on your left), signposted as a 'Camping area'[141].

Mooney Mooney Creek Campsite (north) Alt = 7 m
This signposted[142] campsite is sits among the tall eucalypt and bracken fern forest[143] beside the Mooney Mooney Creek. This is a very pleasant flat clearing to spend a night, there is a small metal fireplace hotplate[144] and room for a small number of tents. There is No drinking water or other facilities at this campsite (Mooney Mooney Creek is salty at this point, treatable water may be found about 2km north).

Day 2


(13.49 km) Mooney Mooney Creek Campsite (north) to Ausburn Creek crossing
Track: Moderate - bushtrack
Length = 1.22 km Time = 22 mins
Climb = 30 m Descent = -18 m
Continue straight: From the campsite[145], this walk follows the clear track north, keeping the wide Mooney Mooney Creek to your right. The clear, wide and mostly flat track leads alongside the creek[146] for about 1.2km to come to the southern bank of Ausburn Creek[147] (about 130m past a rock wall[148], on your left), a few metres above its confluence with Mooney Mooney Creek[149]

(14.71 km) Ausburn Creek crossing to Mooney Mooney Creek crossing
Track: Moderate - bushtrack
Length = 855 m Time = 22 mins
Climb = 64 m Descent = -54 m
Continue straight: From the south bank of Ausburn Creek, this walk crosses the narrow rock platform and creek[150], then follows the track fairly steeply uphill[151] for about 200m. At the top of this climb, the track gently undulates[152] alongside Mooney Mooney Creek for about 700m before heading down to find a large rock platform[153] on the western bank of Mooney Mooney Creek. This large rock platform is a natural ford of the perennial Mooney Mooney Creek[154] and is home to a scattering of small and large waterholes[155].

(15.56 km) Mooney Mooney Creek crossing to Lower Mooney Mooney Dam
Track: Moderate - bushtrack
Length = 1.22 km Time = 28 mins
Climb = 71 m Descent = -44 m
Continue straight: From the bank of Mooney Mooney Creek, this walk crosses the wide rock platform[156] and creek[157] to find the track again on the other side[158]. This creek may become impassable after heavy or prolonged rain. Here the walk turns left and follows the rocky track that leads gently up alongside the creek through the pleasant forest[159]. After a little over 1km, the walk comes into view of the tailwater of the dam[160] and then past a fenced cutting[161] (on your right), the site of an old pump house[162]. About 60m past this fenced area, the walk leads up along the now widening track to find the edge of the fenced lower Mooney Mooney Dam wall[163].

Lower Mooney Dam Alt = 40 m
Lower Mooney Dam[164] is located on the Mooney Mooney Creek, about 21 km upstream from the Hawkesbury River. In March 1938 the Gosford Mayor turned the tap to add the water from this dam into the small town water supply of the time[165]. It is a concrete arch dam, with a capacity of 1,000 megalitres[166], and was superseded by the more than 4 times larger 'Upper Mooney Dam' in 1982. There is a set of timber steps and a faint track that leads down to the waters edge on the uphill side of the dam wall[167], the dam wall is fenced and is clearly out of bounds[168]. A sign reminds visitors that swimming is not allowed[169].

(16.78 km) Lower Mooney Mooney Dam to Quarry Camping Area
Track: Moderate - bushtrack
Length = 2.19 km Time = 53 mins
Climb = 180 m Descent = -35 m
Continue straight: From the lower Mooney Mooney Dam[170], this walk heads uphill along the old trail[171], initially keeping the water on your left. The trail leads up, enjoying the occasional glimpse of water[172] (on your left) for about 400m to pass a washed-out section of the old trail[173]. From here, the walk continues up along the trail for about 1.3km, getting steeper as it climbs, and comes to a three-way intersection marked with a 'Mooney Creek' sign[174] pointing back downhill.
Turn left: From the intersection, this walk follows the 'Reserve Road' sign[175] uphill along the old trail, initially keeping the valley to your left[176]. After about 180m, this walk comes to a faint intersection marked with a 'The Great North Walk' sign[177].
Turn left: From the intersection, this walk follows the 'The Great North Walk' sign[178] downhill along the track for about 50m, to crosses a small pleasant gully[179] with an ephemeral creek[180]. After this, the track starts to wind moderately steeply uphill[181] then, soon after flatting out, it comes to a signposted 'Camping Area'[182] with a metal fireplace[183].

Quarry Camping Area Alt = 202 m
This is a small signposted campsite set among heath, grass tress, scribbly gums and aother eucalpyts[184]. The clearing is flat and sandy and provides room to set up a few tents with and a small metal fireplace with hotplate[185]. There is no water or other facilites here.

(18.97 km) Quarry Camping Area to Quarry gate
Track: Moderate - bushtrack
Length = 593 m Time = 11 mins
Climb = 14 m Descent = -4 m
Continue straight: From in front of the 'camping area'[186], this walk heads gently uphill along the sandy track[187], initially keeping the camping area to your right. After about 220m of walking through this scribbly gum forest[188] and passing a small informal campsite[189] on the way, this walk comes to the quarry boundary fence[190] and turns left[191]. Following the fence for about 70m, the track leads to a section of timber boardwalk[192] with a view (right) over parts of the quarry[193]. The walk continues along the fence for just over 250m, crossing a small flat timber bridge[194] to come an intersection with a dirt road[195] (just past the locked gate).

(19.57 km) Quarry gate to South end of Robinson Crk Track
Track: Moderate - road,bushtrack,bushtrack
Length = 1.72 km Time = 34 mins
Climb = 52 m Descent = -52 m
Veer left: From the intersection, this walk follows GNW arrow marker[196] gently downhill along the dirt road[197]. This walk follows the road for about 400m to come to a large clearing with two large water reservoirs tanks[198]. This walk continues past the two reservoirs[199] (and past the treatment plant building[200], on your left) to come to a 'The Great North Walk' sign[201] just in front of a small brick building[202].
Continue straight: From the brick building[203], this walk follows the 'The Great North Walk' sign[204] gently downhill along the gravel trail (away from the water tanks) for a few metres before turning right onto a track, following a GNW arrow post[205]. This track leads through the banksia and she-oak forest[206] for just over 100m to pass a 'The Great North Walk' sign[207] and then cross Reservoir Rd[208]. On the other side of the road, this track continues gently down through the she-oak (Casuarina glauca) forest[209] for about 150m before crossing a metal footbridge[210]. On the other side of the bridge, this walk turns left and follows the track as it winds down through the heathy bushland, alive with wildflowers[211] in spring, for about 400m and crosses a small ephemeral creek[212]. The track then leads under a set of high tension power lines and then bends right and leads gently up for another 20m, coming to an intersection with a power line management trail[213].
Veer right: From the intersection, this walk follows the management trail uphill[214], keeping the power lines just to your right. After about 40m, this walk follows the GNW arrow post left[215] (ignoring the 'Private Property'[216] trail ahead) as the track winds gently uphill for about 250m before veering left, ignoring another 'Private Property' track[217] (on your right). The mostly flat track now leads along the side of the hill[218] for about 100m before passing under another set of power lines[219] and leading right, steeply up the short rocky hill[220]. At the top of this hill, the track leads to the end of a trail[221], but immediately veers right[222] to follow a track along a fence for about 60m before rejoining the same power line management trail[223].

Veer right: From the intersection, this walk follows the GNW arrow post uphill[224] along the wide management trail, following the power lines for about 100m before veering left to follow another GNW arrow post[225] along a narrow track.
The track leads into the bush among gymea lilies[226] (Doryanthes excelsa[227]) and eucalypts[228] for almost 300m, crossing a couple of short flat timber bridges[229] to then head along a few sections of timber board walk through a weedy section[230] of bush. The track then continues gently downhill for another 150m to cross over a trail[231]. Following the GNW arrow post, this track now begins to lead more steeply down for about 250m, passing through another large grove of gymea lilies[232], a small cave[233] (on your left). The walk continues down the timber then stone steps[234] to head into the dense moist forest and across a flat timber bridge[235], coming into view of the creek[236]. Here the walk bends right and leads beside the creek for a short time before bending left, following the GNW arrow post across the creek flowing over the mossy rock bed[237]. Just downstream is a small pool and cascade[238].
Here the walk starts to climb up the other side of the valley[239], soon crossing a small flat timber bridge[240]. The track then winds steeply[241] out of the ferny and densely forested valley, up a series of timber and stone steps for about 130m where another GNW arrow post marks[242] the end of this section of steep climbing. This track now leads gently up among some tall eucalypts[243] and past a large grove of gymea lily[244] for about 230m to come to a T-intersection[245] with a wide management trail.

Veer right: From the intersection, this walk follows the GNW arrow post uphill[246] along the wide sandy trail for about 40m to pass a faint trail[247] (on your right). Then about 120m further up the main trail, this walk comes a T-intersection[248] marked with a couple more GNW arrow posts.
Turn right: From the intersection, this walk follows the GNW arrow post[249] gently uphill along the sandy trail[250]. The trail soon leaves the wooded forest and after about 120m, this walk veers left at an intersection in a clearing[251]. After another 120m, the walk heads past a large grassy clearing[252] (on your right) with some tall pine trees[253]. The sandy trail continues for another 150m, past a few scribbly gums[254], and comes to a Y-intersection marked with a 'The Great North Walk' sign[255] (pointing left).

Veer left: From the intersection, this walk follows the 'The Great North Walk' sign[256] along the track, initially keeping the sandy trail to the right for a short distance. The track soon bends left, then winds over a small rise through the scribbly gum forest[257] for about 400m before heading over a short section of green boardwalk[258]. A short distance later, this walk crosses a green timber footbridge[259] and comes to an intersection at the end of the dirt Robinson Road[260].

Turn right: From the intersection, this walk follows the GNW arrow post[261] uphill along the gravel Robinson Rd for about 300m to then continue straight ahead[262] along the sealed Silvester Rd. This walk heads along the sealed road for another 500m to pass an intersection with 'Anembo Rd'[263], then continues along Silvester Rd. Over the next 1km or so, the walk travels among the rural properties[264], passing some distant views of the peaks in Brisbane Water NP[265] (to your right), before turning left onto Wisemans Ferry Road at the T-intersection[266]. From this intersection, this walk leads up along the narrow grassy verge beside[267] the road for about 500m to pass the large communications[268] tower (on your right), heads over the crest of the hill then down for about 250m to come to Somersby Store[269] (on your left).

11th April 2010.
We have just come back from this walk with the family. 2 sons, 6 and 8 years old and my wife.

Did not see anyone else on this track walking in 2 days. Weird!

Notes and details were excellent and got alot of use from them.

The watchout is that from the Mooney Mooney campsite to the Mooney Dam is leech infested. I have never seen anything like it. Take the salt and the Deet for you ankles and do not stop walking as they are all under the leaves on the track
Nat N - Leeches - beware! IP:27.32.46.xxx | 2012-05-15 09:39:33
Ditto David F's comment. Loads and loads of leeches.

The campsite at Mooney Mooney is nice, level, etc, but absolutely crawling with leeches. If you can walk the extra 2 hours you'll be more comfortable camping at the Quarry campsite.
Jason W - Somersby Store closed Sundays IP:60.228.57.xxx | 2012-10-21 09:33:53
We've just done an overnighter from Wondabyne Stn to Somersby Store. Great walk, and the Quarry campsite is the pick as Nat N pointed out.
We were really looking forward to a coffee and a snack when we arrived at Somersby Store, but there was a note on the door saying it is now closed on Sundays. Oh, well.
There's also a sign on the door saying the store is for sale. hopefully if it is sold the new owners will reconsider.
BTW, awesome website guys. I've just bought your book on the GNW, so plenty of inspiration for the remaining legs.
Karen - Kariong scout camp great place IP:110.142.141.xxx | 2013-06-02 02:29:30
We walked Wondabyne to Somersby last week.Beautiful wildflowers, easy first day to Kariong scout camp. A lovely stay in their cabin. Walked out to Somersby store next day. Quite damp and muddy on track despite no recent rain.Good coffee but no real supplies at Somersby store. It is quite difficult to get a bus back to Gosford. Overall a peaceful pleasant two day walk. Enjoy.
