Whakamaru Reserve sits on the edge of Lake Whakamaru along Ongaroto Road in the South Waikato, roughly 90 minutes from Hamilton and 35 minutes from Taupo.

The reserve offers a generous stretch of grass along the lake shore, with a boat ramp at the north end and a small beach at the south end. Facilities include a toilet block, BBQ area, and broad open views over the water.

The reserve is a designated stop on the Waikato River Trails and sits close to the Ongaroto Bluffs Staircase scenic lookout and the nearby Whakamaru Dam.

Freedom camping is permitted, with self-contained vehicles able to stay up to two nights without a permit; longer stays and casual campers require a permit through South Waikato District Council.
