This is definitely one of the hidden gems of Iceland. This natural geothermal pool is located in the highlands in the east and not many people travel all this way. You will need a 4x4 car to reach this waterfall.

The warm water comes down a waterfall making it a nice natural shower. The water temperature varies, but it usually stays around 104 degrees Fahrenheit (about 40ºC). Not far from the hot pot, there's also a campground.
