The Glendhu Bay Recreation Reserve Boat Ramp is one of several public boat launching facilities on Lake Wānaka, New Zealand's fourth largest lake at 180 km² and up to 300 m deep.

It sits along the lake's western shore, providing boaters with access to the broader lake system. As with all of Lake Wānaka, a 5-knot speed limit applies within 200 metres of shore.

The ramp serves anglers, recreational boaters, and others exploring the lake, including the largely boat-access-only western shoreline. Shore fishing opportunities are also available in the bays near the launching facility.
