The Tree Trunk Gorge Track is a 5-kilometre one-way trail through Kaimanawa Forest Park linking the Tree Trunk Gorge Road trailhead to the Urchin Campsite on Kaimanawa Road. The track passes through native beech and kamahi forest, crosses two gorges on the upper Tongariro River system, and includes river crossings that require care — particularly after rain. It is used by both walkers and mountain bikers and takes approximately 1.5 hours to walk one-way. Access is from either end; a vehicle at both ends or a return trip is required.

The Track
The Tree Trunk Gorge Track runs through the heart of Kaimanawa Forest Park in North Island beech forest — the characteristic high-altitude forest of red, silver, and mountain beech. The track passes along the upper Tongariro River, crossing two gorge sections where the river has cut through the volcanic plateau. The gorges are the highlight of the route — steep-sided ravines in dark rock with clear river water below.
River crossings are part of the route and the track can be impassable after heavy rain when the river rises. Check conditions with DOC before heading out, particularly in winter or after wet weather. The track is signed from both ends.
For Mountain Bikers
The Tree Trunk Gorge Track is rated Grade 4 for mountain biking — suitable for experienced riders comfortable with technical terrain and river crossings. The single-track trail through the forest is engaging, with the gorge sections providing the most challenging riding. Most bikers start from the Tree Trunk Gorge Road end and ride to Urchin Campsite, then return the same way or arrange a shuttle. Allow approximately 1 hour for the one-way ride. Be prepared to carry or walk the bike through the river crossings.
