Atuatumoe Falls — also known as Sleeping God Canyon — is a dramatic cascade on the Kauaeranga River in the Coromandel Forest Park on New Zealand's Coromandel Peninsula.

The waterfall system drops over 300 metres through a steep, rugged canyon, forming a series of falls, water slides, and deep pools carved into the valley's rocky terrain.

The canyon sits within the broader Kauaeranga Valley, a scenic area administered by the Department of Conservation and framed by peaks such as Table Mountain and the Pinnacles.

The Kauaeranga River itself takes its name from the Māori "Waiwhakauaeranga," a reference rooted in the history of the Ngāti Maru people.

The falls are best known as the setting for guided canyoning descents, which involve abseils of up to 80 metres, jumps into deep pools, and zip lines through the valley — making Atuatumoe one of the more challenging and celebrated natural adventure sites in New Zealand.
