Starting with a steep climb from Wondabyne Train station you will explore a series of large rock platforms with wide views over the Brisbane Water National Park and visit Scopas Peak. When back in the valley you'll walk along the cool Mooney Mooney Creek before reaching Somersby. The rural area is soon left behind when you reach rainforest of the Palm Grove Nature Reserve where you can observe the Strangler Fig Trees, Cabbage Palms and Eucalyptus trees. You'll pass the rural area of Ourimbah Valley to get to the historic Bumble Hill Dray Track and finish the walk at Yarramalong. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
Before you start any bushwalk ensure you;
• Tell someone you trust where you are going and what to do if you are overdue
• Have adequate equipment, supplies, skills & knowledge for the whole journey
• Consider the impact of weather forecasts, park/track closures & fire dangers
• Can respond to emergencies & call for help at any point
• Are healthy and fit enough for this journey
If not, change plans and stay safe. It is okay to delay and ask people for help.
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.
