Hogan Track & Old River Hike (24km)

The Hogan Track–Old River Circuit is a demanding 24-kilometre loop nestled deep within Lerderderg State Park, Victoria. Graded at level 4, this full-day hike typically takes between 8 to 9 hours to complete and is best suited to experienced hikers who are comfortable with off-track navigation and rugged terrain. What makes this route particularly rewarding is its immersion in the remote and lesser-visited reaches of the Lerderderg Gorge, where the scenery is wild, raw, and untouched by crowds. For those seeking solitude and a deeper connection to the landscape, this hike delivers.

The walk begins on a well-formed management track, descending steadily as you make your way into the heart of the gorge. This initial stretch provides a chance to settle into the rhythm of the trail before things get trickier. As you near the river, the track joins the eastern end of Ah Kow Spur, where the descent steepens considerably. This final section is rough underfoot, with loose surfaces that demand concentration and care.

Once you reach the river, the trail disappears entirely. From here, navigation is essential. You’ll need to traverse the terrain by feel and map, making your way through dense bush, across the river multiple times, and over slick rocks. The journey between Ah Kow Spur and Old River is entirely off-trail and can be disorienting if you're not paying close attention. One critical landmark to watch for is the mouth of Old River. It's surprisingly easy to miss, and doing so could lead you far off-course, with little opportunity for a quick return.

From the confluence, the hike follows the length of Old River as it winds through a steep, enclosed gully. Walking this section means weaving through undergrowth, hopping rocks, and occasionally climbing over obstacles. The river rarely offers a straightforward path, but that’s part of the appeal. This is not a manicured walk, but rather an immersive experience in a place where nature calls the shots. Exits from the gully are limited until you get closer to its upper reaches, so patience and persistence are key.

Eventually, you’ll need to find a suitable spur on the left side of the gully to climb back out. There's no set point for this—let your energy levels, time of day, and terrain guide your decision. Once you've made the ascent, the route rejoins Hogan Track. From here, it’s a straightforward return to your starting point, giving you time to reflect on a route that’s equal parts demanding and rewarding.

This hike isn’t for everyone, but for those with the right skills and a taste for adventure, the Hogan Track–Old River Circuit offers a true wilderness experience, far from the noise and structure of more familiar trails.
