Girrakool picnic area is a wonderful family destination, just 5 minutes' drive from Kariong. The picnic area provides all the necessary facilities for a full day's activities, including barbecues, tables, shelters, water and toilets. National Park fees apply. The main picnic area is on the eastern side of the car park, and smaller, older picnic area is at the north-eastern corner of the car park. The southern Girrakool picnic area is located near the toilets. The picnic area is dedicated to John 'Jack' Higgs, the first superintendent of Brisbane Water National Park, and Mrs Vera Murdoch, who provided the funds. 'Girrakool' is an Aboriginal word meaning 'place of still waters'. More info

Time = 1 hr 18 mins
Climb = 271 m
Descent = -81 m
Turn sharp left: From the intersection, this walk follows the 'Patonga Ferry' sign up the side of the gully, keeping the intermittent creek to your left. The track leads past a 'Patonga' sign then winds steeply up the hill for about 130m, through a cleft in the rock and past a few rock walls, and then the track mostly flattens out with some filtered distant views. The track continues gently uphill for another 300m, becoming progressively flatter before passing along the side of a long rock wall, with a tall sandstone overhang. The track then crosses a small gully and leads past another overhang, where the track begins to lead downhill. The rocky track winds steeply downhill for about 130m to then cross an intermittent creek which flows over the solid sandstone platform. Continue straight: From the west side of the creek, this walk climbs uphill following the rocky track. The track climb for about 600m, fairly steeply for a while then becoming progressively less steep. The track passes a couple of rocky outcrops to then come to a large flat rock platform, with distant views. The rocky track then leads off this rock platform and continues up the ridge for just shy of 300m to come to the edge of a much larger rock platform with more views. A series of GNW arrow posts lead across this rock platform, generally leading towards Scopas Peak for about 400m where the arrows lead off the rock platform and back onto a heathy track. Keeping Scopas Peak up to the left, this track leads around the side of the hill for about 150m to pass a view across the valley to Mooney Mooney Bridge. Over the next 800m, the track leads up across a few more rock platforms then climbs fairly steeply up to a view point, just to the west of Scopas Peak.
South end of Scopas Peak Track Track: Hard - bushtrack
Length = 1.17 km
Time = 23 mins
Climb = 14 m
Descent = -80 m
Veer left: From the view point, just west of Scopas Peak, this walk heads south steeply down the rocky track, initially keeping the distant view to your right. The track leads steeply down past a few rock walls then climbs down over some rocks with cut steps, enjoying more views for about 230m, and then the track mostly flattens out to lead gently down across the narrow saddle. The track gently undulates along this ridge for about 750m to come to a green painted metal box on a post (on your left), containing a Great North Walk intentions book. Continue straight: From the Great North Walk intentions book, after leaving your comments, this walk heads south, gently downhill along the clear track. After about 150m, the walk comes to a T-intersection with the Gosford Rifle Range trail - At this intersection is a 'Girrakool' sign, pointing back along the track.

Turn left: From the intersection, this walk follows the 'Patonga' sign heading east down along the rocky track. The track soon bends right and heads around a rock outcrop then continues down through the heath and scribbly gums for about 400m to come to a flat rock platform. Here the track continues downhill over several more rock platforms, becoming progressively steeper for just over 1km to head into the cool valley and come to the bank beside Myron Brook. Continue straight: From the western side of Myron Brook, this walk crosses the creek on the sandstone rock platform to follow the track up a few stone steps and up the short steep hill. The track then flattens out as it leads around the side of the hill for about 200m to pass alongside a long rock wall (on your left). Now leading downhill, the track continues for another 100m then heads down a short steep section into the dense moist gully, coming to a faint intersection in front of Kariong Brook Falls (on your left) (just before crossing the creek, which is often underground). (Retrace your steps back to the main track, then turn left to continue along this walk.)

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.
