The Lerderderg State Park is rugged and remote with limited directional signage. You should be prepared for all conditions and have suitable navigation experience (not just a phone app) before venturing beyond the main picnic/parking areas or Grahams Dam. Many rescues have occurred in this park that could have been avoided.
The Blue Gum Loop is a captivating 22-kilometre hike that winds through the scenic Lerderderg State Park in Victoria. This Grade 4 trail typically takes around six to seven hours to complete, offering a diverse mix of terrain that is sure to keep hikers engaged. The loop begins at the corner of Blue Gum Track and O’Briens Road, where the first few kilometres involve walking along the road. While this initial section is straightforward, it sets the stage for what’s to come as you make a right-hand turn onto the trail.
From here, the trail takes you on a gradual descent, with a few short, steep sections leading down to a creek bed. You’ll cross this creek before tackling a brief but steep hill climb, followed by a descent to another part of the creek. The path then begins to climb again, with a fairly gentle uphill stretch after the initial steep ascent. This steady climb takes you through a series of stunning landscapes, all while immersing you in the natural beauty of the park.
If you’re looking to shorten the hike, you can cut about 6 kilometres off the total distance by heading directly to Firth Road. Alternatively, if you’re keen to explore more, continue along the trail, which undulates through lush fern-filled valleys. There are a couple of short off-track sections to navigate, but the trail soon rejoins tracks that run alongside Firth Road. At times, you’ll be walking along the road itself as you make your way back to the starting point.
This hike offers a wonderful blend of easy-to-follow tracks, off-track sections, and the beauty of both open landscapes and secluded creek areas. It’s an excellent choice for those who enjoy a mix of road walking and nature immersion, with the flexibility to adjust the distance according to your preferences.

Rising in the Great Dividing Range, the Lerderderg River has cut a 300 metre deep gorge through sandstone and slate, almost bisecting the park. The park has a wide variety of vegetation and wildlife and some interesting relics of gold mining. Lerderderg State Park encompasses scenic and geological gorge formations surrounding the Lerderderg River as well as the volcanic cone of Mount Blackwood. The adjacent and separate block called the Pyrete Range forms part of the park. The Lerderderg is known for its remote setting and the 300m deep Lerderderg River gorge is a dominant feature. Private land abuts the park to the south and the Wombat State forest abuts to the north and west.
Lerderderg State Park (incorporating the former Pyrete State Forest) is a 14,250-hectare park located between Bacchus Marsh and Blackwood, an hour's drive from Melbourne, Australia. There are several maintained tracks for walking through the park and camping is allowed.
The park is named for the Lerderderg River which has cut the 300 metre deep Lerderderg Gorge through sandstone and slate, almost bisecting the park. Parks Victoria maintains six designated walks: three short walks of 3.5 km or less; Blackwood-O'Briens Crossing and return (22 km); O'Briens Crossing-Cowan Track loop (14 km); and the overnight walk O'Briens Crossing to Mackenzies Flat (20 km).
In addition, one leg of the Great Dividing Trail, the Lerderderg Track, passes through the park, entering from Blackwood in the park's northwest, and exiting south towards Bacchus Marsh. Bicycles are prohibited from one section of this track, due to a conservation area.
