A pleasant walk through kamahi forest with views of the Tongariro River below. Return via same track, or along the road.

The Pillars of Hercules: This deep gorge has a complex history of formation. The river has eroded a narrow channel through ancient lava flows (350,000 years and older) of andesite and ignimbrite rock.

You can view the spectacular ravine from a 40 m long suspension bridge, which you can reach via the walking track, or alternatively from the car park 2 km along Kaimanawa Road.

This feature is even more spectacular from the air as the Tongariro River can be seen to suddenly narrow as it passes through this chasm.

Both walks start at the Urchin Campsite 3 km along Kaimanawa Road. Kaimanawa Road is off SH1, 15 km south of Tūrangi.
