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.

Broula Lookout Broula Lookout is fenced and a fairly short walk down from the Girrakool picnic area. Over time, the trees in the area have grown, filtering what would otherwise be a great vantage point for the Piles Creek waterfall. Broula is an Aboriginal word referring to a place of trickling water.
	After another 25 m (at the intersection of Girrakool Loop Track & Piles Creek Loop) turn left, to head along Piles Creek Loop. After another 40 m find the "Illoura Lookout" (on your right).

Illoura is an Aboriginal word referring to a pleasant or peaceful place. After another 7 m (from the Piles Creek Loop) continue straight, to head along Piles Creek Loop. After another 20 m find the "Piles Creek Waterfall" (on your right). Piles Creek Waterfall The large waterfall on Piles Creek is south of Girrakool Picnic Area in Brisbane Water National Park. At the Piles Creek Loop track crossing at the top of the falls, there is a large rock platform. The cliff edge is unfenced and would be dangerous to approach for the view. The water falls down the large drop, into a big pool below. The 'Bundilla Lookout' on the other side of the valley provides the only square view onto the falls, but even this only witnesses the top half.
	After another 910 m (from the Piles Creek Loop) continue straight, to head along Piles Creek Loop.
	The starting point of an optional sidetrip. An optional side trip to Piles Ck Lookout. To start this optional side trip turn right here. On returning from this side trip turn left when you get back to this intersection. Details below. After another 135 m (from the Piles Creek Loop) continue straight, to head along Piles Creek Loop. After another 150 m find the "Monolith Cave" (on your left). Monolith Cave Monolith Cave is an informally named cave and interesting rock formation high on the ridge east of Piles Creek and North of Rat Gully in the Brisbane Water National Park. The cave is a fairly large sandstone overhang on the edge of the track. The cave provides shelter for walkers and is a great spot to rest and enjoy the area. This rock and the more Monolithic rock about 60m to the south are interesting to explore, and provide great views of the surrounding area. Take great care if exploring the rocks.
	After another 390 m (from the Piles Creek Loop) turn left. After another 1.3 km come to the viewpoint. After another 305 m come to the viewpoint. After another 1.4 km pass the "Scopas Peak" (25 m on your left).

	After another 600 m (at the intersection of Rifle Range Firetrail & Pindar Walking Track) continue straight, to head along Rifle Range Firetrail. After another 960 m (from the Rifle Range Firetrail) continue straight, to head along Rifle Range Firetrail. After another 315 m head down the steps (about 30 m long) After another 165 m come to "Wondabyne". Wondabyne 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.
