Waterfall Hut is a historic backcountry hut in Ruahine Forest Park, in the Manawatū-Whanganui region, near Colyton. The Department of Conservation website describes it as a six-bunk hut, built in 1961 for forestry hunters working to control deer, and many of its original features are still intact. Bookings are not required, and the hut works on a first-come, first-served basis. Hut tickets for each night go in the honesty box at the hut, or a Backcountry Hut Pass can be bought for 12 months of use at most standard and serviced huts.
There is no DOC track access to the hut, so visitors must plan their own route and navigate with a map, compass or GPS. The website advises against crossing flooded rivers and streams, and says to turn back if in doubt.
