This is one of the most extrodinary places I have been to. Wai-o-tapu in Rotorua in New Zealand. This lake is kind of boiling, and has to weirdest colors as you can see. The surface is 73 degrees, while at the bottom 62m below it is 260 degrees celsius. There was a strong wind and I had to sit in the very wet steam and wait for spells with less wind and then wait for the lens to be clear.
