Lerderderg State Park and the surrounding Wombat State Forest are north of Bacchus Marsh, around one hour's drive (90 km) (56 miles) from Melbourne on the Western Highway. Its myriad tracks, gullies creeks and ridges form a wild, rugged environment enjoyed by bushwalkers, horse riders and mountain bikers. The striking feature of this area is the 300-metre (975 feet) deep gorge that stretches south to the plains of Bacchus Marsh. Parts of the Wombat State Forest are still actively logged, and some areas are designated for domestic firewood collection with a permit. Many roads in the Lerderderg State Park are closed between June and the beginning of November as the park is within a water catchment area.
The park is popular for bushwalking, as it is possible to walk all day and not see anybody. The most popular areas to start a walk are from Mackenzies Flat Picnic Area and O'Briens Crossing. The best walk from Mackenzies Flat is one which goes up one side of the gorge and back along the other. It goes right up to the Lerderderg Weir. From O'Briens Crossing you can either walk up or down the river. Walking up takes you to The Tunnel. If planning a walk, make sure it hasn't rained much recently, and if walking along the river walk downhill, as the bushes on the riverbed always slope downwards.
