Rotorua, New Zealand

Rotorua, New Zealand

Is the place where it smells like rotten eggs (presence of hydrogen sulfide) and there are plenty of mud volcanoes and geysers. Mud so much that it forms a mud pools, and you can see in this photo. Thermal activity here is due to Rotorua caldera, which is a city of the same name. By the way, the water here is very different colors – from yellow to orange to green. So many tourists come to see this miracle.
