Safety advice

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.

Hike overview

The Bears Head Circuit offers a challenging 16-kilometre hike through one of the most remote and rarely visited sections of Lerderderg State Park in Victoria. With an estimated duration of seven to eight hours, this grade 4 hike is best suited for experienced walkers. It promises solitude, a sense of adventure, and the opportunity to explore a rugged part of the Lerderderg Gorge that many don’t get to see.

The hike begins at the Lohs Lane car park, where you’ll make your way down the Ah Kow Spur Track, which steeply descends towards the Lerderderg River. The track’s final stretch is particularly steep, earning it the reputation of being the steepest spur in the park. As you make your descent, you'll be immersed in the sounds of nature, with the river below becoming an increasingly prominent feature of the landscape.

Once you reach the river, turn right and follow it south for about 2.5 kilometres. There are no trail markers in this section, so navigating along the river can be tricky, requiring you to carefully pick your way across various obstacles, including multiple river crossings. After rainfall, the river can swell, making the crossings more difficult and dangerous, so it's best to avoid the hike if water levels are high.

After following the river, look out for marker LER511, which indicates the start of Bears Head Spur. From here, the real challenge begins. The ascent up the spur is steep and rocky, but the effort is worth it. As you climb, the views open up, and you'll be treated to increasingly spectacular panoramas that push you forward, each step bringing you closer to the top.

Reaching the top of the Bears Head Range is a moment of accomplishment. The sweeping views over the surrounding wilderness are not only breathtaking but also offer a satisfying sense of reward. However, the journey is far from over. While the temptation may be to continue north along the vehicle management track, this is not permitted due to its passage through the Ah Kow Gully Reference Area. Instead, you’ll need to head southeast, following the Blackwood Ranges Track until you reach the Fox Gully Track junction.

From here, follow the Fox Gully Track as it meanders through the gully and eventually returns you to the Blackwood Ranges Track. This section of the hike takes you back towards the start of the Ah Kow Spur Track, bringing you full circle back to the trailhead at Lohs Lane.

The Bears Head Circuit is not an easy walk. It requires a high level of fitness and experience, as the steep ascents and challenging terrain demand physical and mental stamina. But for those who are prepared, the rewards are substantial. The solitude, the beauty of the landscape, and the sense of achievement after completing the circuit make it an unforgettable adventure. If you’re up for the challenge, the Bears Head Circuit offers one of the best ways to experience the rugged wilderness of Lerderderg State Park. Just make sure you’re in good physical condition and ready for the demands of a true bushwalk before setting out.

Tips

  • The descent into the gorge via Ah Kow Spur is steep and slippery. Take great care in this section of the track. There are multiple river crossings and rock scrambling which make this hike suitable for experienced hikers only.
  • Hiking poles recommended.
  • Start early in the day, as the hike can take up to 7 hours to complete.
  • Wear sturdy footwear with good ankle support. I also highly recommend water shoes if you have them as it will make the crossings easier.
  • Bring plenty of water, as there is no 'treated' drinking water available on the hike, other than the river.
  • Be prepared for all types of weather conditions, as the weather in the Lerderderg Gorge can change quickly.
  • Let someone know where you are going and when you expect to be back.

About the region

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.
