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.
This hike starts from O'Briens Crossing Camp Ground and follows the famed East Walk along the eastern banks of the Lerderderg River. This part of the circuit twists and turns along intermittent water races and foot trails for approximately 5.3Km before ascending Nolan Spur to intersect the end of Nolan Track. Ascend Nolan spur (initially steep) and follow it along its length for approximately 3Km to its end at O'Briens Road. Walk along O'Briens Road for 500m until you reach Gribble Track on your right.
After following Gribble Track for almost 2.5Km you will arrive at the junction of Byers back Track. You can turn right at this point and return to O'Briens Crossing. This hike continues straight ahead descending the steep track down to the Lerderderg River and the Tunnel.
The track then leaves the downstream of the tunnel entrance and continues across the Eastern bank of the river. The trail beyond this point is not particularly easy to follow and in some places it may be easier, during drier weather, to simply follow the Lerderderg River through to the Ambler Lane ford. There is a section on this part of the trail that requires you to scramble over a cliff face before descending to the river.
From Ambler Lane ford contunie downstream along the Lerderderg River for approximately 1km until you reach a trail on your right. Return via this trail to your starting point at O'Briens Crossing.

A varied hike with steep sections and changing scenery. Hiking poles will be useful on ascents and descents. Carry at least 2 litres of water and food to keep your energy levels up. There are some steep sections that will benefit from the use of poles. Following rain, when the river is high, several creek crossings may be required. The trail along the Lerderderg River following the Tunnel is not marked and you will need to pick your way along its length. Best not to attempt this section following heavy rains.

It’s a good idea to let someone know where you’re going. Fill in a trip intention form to send important details about your trip to your emergency contact. If you are lost or require help and have phone reception, call 000 and ask for police. The international standard emergency number is 112, if you dial this number in Australia you will be treated exactly the same as a 000 call. If you believe your life is at risk, activate your personal locator beacon (PLB), then make your position visible to rescue teams and keep warm and dry.
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.
1 Review on “East Walk - Nolan Track and the Tunnel (12.8km)”
This is a very good hike!
The last quarter of this track along the river is now hard to find and when you do find it it is overgrown with a lot of climbing over and around fallen trees required. If walking off track isn’t something you enjoy then turn right at Margarets Corner onto Ambler Lane then left onto Byers Back track which will take you back to O’Brians Crossing
