The Tree Trunk Gorge Track is a 5 km one-way shared-use trail in Kaimanawa Forest Park that connects the Tree Trunk Gorge Road trailhead with Urchin Campsite on Kaimanawa Road. It passes through native beech and kamahi forest while crossing streams and following the line of an old road associated with the Tongariro Power Scheme. Walkers and mountain bikers both use the route, which features two spectacular gorges and offers views toward Tongariro National Park from an open ridge near one end. The track is managed by the Department of Conservation and requires care at stream crossings, especially after rain. Access is possible from either end, so most visitors arrange transport or complete a return trip.

About Tree Trunk Gorge Track
The Tree Trunk Gorge Track lies within Kaimanawa Forest Park in the central North Island. It follows a well-graded route that was once part of infrastructure for the Tongariro Power Scheme and now provides access through characteristic red beech forest with kamahi present in places.
Two gorges form the scenic highlights where the track crosses the upper reaches of the Tongariro River system. An open ridge near the Tree Trunk Gorge Road end offers views across to Tongariro National Park.
Stream crossings are a feature of the route. Several small streams and one larger crossing occur along the way, and conditions can change quickly after heavy rain. The Department of Conservation advises checking current conditions before travel, particularly in winter or wet weather.
The track is signed from both ends and is suitable for day trips. It forms part of the broader network of walking and mountain biking opportunities in Kaimanawa Forest Park, where hunting is also permitted.
Walking the Track
Walkers typically allow 1.5 hours one-way. The route is generally well graded but includes stream crossings that may require wet feet in normal conditions. Most people start from either the Tree Trunk Gorge Road end or Urchin Campsite and return the same way or arrange a vehicle shuttle.
Mountain Biking the Track
Mountain bikers complete the one-way ride in about one hour. The track is shared use, so riders must follow the mountain bikers code and give way to walkers. The gorge sections and stream crossings add technical interest. Many riders start at Tree Trunk Gorge Road and continue to Urchin Campsite before returning or linking with other routes such as the Urchin to Pillars of Hercules Track for a longer loop option.
What Visitors Often Say
Walkers and riders describe the track as scenic and rewarding, with the gorges and forest providing a peaceful setting away from busier trails. Many note the stream crossings as a highlight or challenge depending on water levels and appreciate the well-graded surface that follows the old road alignment.
Visitors often mention the need to check weather and river conditions in advance. Some combine the track with a longer loop via the Pillars of Hercules for a full day out, while others enjoy it as a straightforward there-and-back or shuttle trip.
