Rere Falls and Rere Rockslide sit side by side on the Wharekōpae River, about 45 kilometres northwest of Gisborne in the foothills of the Huiarau Range.

The falls are a broad, curtain-style drop — roughly 5 metres tall and 20 metres wide — set against a backdrop of farmland. Visitors can walk behind the cascading water, though the rock face is notoriously slippery. The rockslide is the bigger draw.

Over thousands of years, the river has worn a smooth, angled rock face into a natural waterslide 60 metres long, pitched at roughly 30 degrees and ending in a large swimming hole. Riders typically use boogie boards or tyres to make the run.

The New Zealand Automobile Association has listed it among its 101 Must-Do experiences for Kiwis, and the reserve includes parking, picnic facilities, and a public toilet.
