Serene Lake Mahinapua and its diverse forests lie 10km south of Hokitika. The scenic reserve, gazetted in 1907, has a picnic area and DOC campsite that bask in mountain views, and the shallow, lagoon-fed water is warm enough for a paddle. There are several short walks (an hour return or less) signposted along the shore.
The starting point of the Mahinapua Walkway is 8km south of Hokitika. It's an easy four- to five-hour return walk following an old logging tramway.
