There is so much to do at Lake Kaniere, it is worth spending a day there.
Here are some ideas.
Cycle the West Coast Wilderness Trail which goes by the lake.
The Lake Kaniere Walkway is a beautiful walk that traverses native bush along the western shore.
The more adventurous and fit can tackle the dayhike up Mt Tuhua or stay overnight at Mt Brown Hut.
Do one of the best half day scenic drives around. Head to Hokitika from the lake via Dorothy Falls and the stunning Hokitika Gorge.
