Tupapakurua Falls is a walking track to a waterfall in Waimarino, Ruapehu, rated 4.6 on Google from 38 reviews. The track starts at Fishers Road, and reviews mention the waterfall, the forest walk and the lookout.
The website describes an easy 20-minute walk to the Taranaki Lookout, with views of Mount Taranaki and Mount Ruapehu. From there the track becomes rugged, dropping to a stream where the falls sit in regenerating forest, and it can be slippery after rain. The Department of Conservation maintains the track to the lookout but not to the falls, so take warm clothes and tell someone your plans.
For walkers in Ruapehu who want a forest walk with a lookout and a waterfall, this track from Fishers Road is worth doing in fine weather.
