This geothermal area sprang to life as a result of the hydroelectric tinkering that created the power station. When underground water levels fell and pressure shifted, new steam vents and bubbling mud pools sprang up. The perimeter loop walk takes about 45 minutes and affords great views down to the lake and mountains beyond. There's a kiosk at the entrance, staffed by volunteers who keep an eye on the car park. It's signposted from SH1m about 5km north of Taupo.
