Overview
Access
By road the best access is off the Old Pacific Hwy between Mooney Mooney Creek and Girrakool Picnic Area, not far out of Gosford. The Woy Woy Road west of Woy Woy also passes through the park and gives access to fire trails and walking tracks. By rail, Wondabyne railway station is the best choice. It lies in the middle of the park and is the only access to some areas, as it is inaccessible by road. You will need to inform the guard if you want to get off as trains only stop by request.
Activities
Bushwalking
For a relatively small park there is quite a variety of bushwalking to be had. Good day walks from Wondabyne Station include to Pindar Cave and Wondabyne Trig. Patonga to Wondabyne is a longer day walk that can be linked by public transport at both ends. The Great North Walk runs through the park as well, and the main track passes through Patonga, Girrakool and Somersby Falls, a section that is best done over a couple of days.
Canoeing/Kayaking
There are three main waterways that are within the park, although generally not protected below the high tide mark. Flat water paddling on all of these can be undertaken. Patonga Creek, Mullet Creek and Mooney Mooney Creek can all give water access to some of the more difficult to reach sections of the park. To head further out on to the Hawkesbury River, a sea kayak is recommended.
