Boonoo Boonoo Falls is a dramatic 210-metre waterfall on the Boonoo Boonoo River within Boonoo Boonoo National Park, located about 35 kilometres east of Tenterfield in northern New South Wales.

The river cascades over a granite cliff edge before plunging into a rainforest-filled gorge below. The falls are particularly spectacular during and after heavy rain.

A short, clearly marked 700-metre return walking track leads from the picnic area to a viewing platform overlooking the falls and gorge.

Visitors can also scramble down across boulders to reach swimming holes and rock pools along the river when water levels allow.

The surrounding bushland supports diverse wildlife, including the endangered brush-tailed rock-wallaby, spotted-tailed quoll, platypus, and glossy black-cockatoo.
