Beyond the bridge is the vast expanse of Tongariro Forest Conservation Area, once the source of timber for local mills, but now protected as conservation land thanks to a successful campaign in the 1980s led by local people to save the forest from clearance. Bisecting the forest is one of New Zealand's best mountain bike rides, the 42 Traverse. The forest also has excellent tramping, camping and deer hunting opportunities. In the heart of the regenerating forest is one of only a handful of national kiwi sanctuaries where the Department of Conservation controls alien predators to protect a population of the North Island Brown Kiwi.
