Carved through the hills for gold mining many moons ago, this track near Ahaura runs through historic tunnels with rivers running through them, and the scenery gets compared to Jurassic Park more often than not. You drop out of native bush down a steep descent into narrow gorges, creek beds and river beds, with waterfalls coming alive when it rains.

Expect a real mix of terrain. Low-range descents, rocky and flexi sections, hidden rocks lurking in puddles, and several river crossings near one end where the track follows the river up. Plenty of optional side tracks and mud holes if you want a harder go. People have done it in everything from stock utes to lifted rigs, so it suits a wide range, though careful driving pays off and going through after heavy rain isn't on.

Landowner permission is required, so call Robyn and Malcolm first. They're friendly, give you a map and a rundown of what to expect, and there's a $20 charge per vehicle. They prefer a two-vehicle minimum for safety, so it's best done as a group.

The farm has a 4WD-accessible camping area with great views, a long drop and a campfire spot for $10 per person a night.
