On my way home I stopped off at Wai-o-Tapu thermal reserve, about 26km south of Rotorua, just off the highway to Taupo. The scenes and colours are dramatic (though the prices are definitely aimed at the tourist market, not NZ families.)
The 'drama' is not just confined to 'big' pools etc. Here is a small fumarole, where sulphur is forming as the steam cools.
These next three photos show some of the drama of the colours at the edge of the Champagne Pool. Where there is a 'whitish' look, it is because steam blew my way, and it was definitely warm steam, like being in a sauna.
