Mangatainoka Hot Springs is a geothermal soaking spot deep in Kaweka Forest Park, situated in the Mohaka River valley on the North Island of New Zealand.

Reaching it requires a 3–4 hour intermediate tramp from the end of Makahu Road, with well-constructed track and bridged river crossings throughout. A DOC campsite sits adjacent to the springs.

The facility features three round geothermal pools set on decking, with valves to adjust the flow. The Mohaka River runs nearby, offering a cold-water contrast to the hot pools.

The remote backcountry setting — lush ferns, forest surroundings, and relative solitude — is widely regarded as what makes Mangatainoka the more rewarding of the two hot springs accessible via Makahu Road.
