The Bridge at Waiotapu Stream — widely known as the Hot ‘n’ Cold — is a free natural geothermal swimming spot on Waiotapu Loop Road, approximately 30 kilometres south of Rotorua via State Highway 5. The spot sits where hot water from the Waiotapu geothermal system flows into a cold-water stream beneath a road bridge, creating a natural mixing zone where you can find temperatures ranging from hot to cold within a few metres. It is open 24 hours a day with no entry fee.

Hot Meets Cold
The appeal of the Bridge spot is straightforward: hot geothermal water, emerging from the Waiotapu system at around 37°C, flows into the same channel as a cold-water stream, and the two mix in the pool under and around the bridge. Finding the right temperature is part of the experience — shuffle around in the water until you land in the zone where hot and cold blend to a comfortable soaking temperature. The hot channel stays consistently warm; the cold channel is noticeably cold. The meeting point between them is the sweet spot.
The spot is genuinely natural and unmanaged — there are no facilities, no changing rooms, and the environment is casual. It is popular with travellers heading between Rotorua and other southern destinations, as it sits conveniently on the Waiotapu Loop Road that runs parallel to SH5.
“The Bridge is one of those rare New Zealand things — a completely free, completely natural hot spring that nobody seems to talk about. Finding the right temperature spot takes a bit of shuffling around but it’s worth it.” — visitor account
