The Boiling Pots are a succession of large pools that are connected by underground rivers or waterfalls. The water rolls like it is bubbling hence the Boiling Pots name.

In some of the pools there are exposed hexagonal columns which help form the basalt lava. Rainbow Falls is 80 feet high and the most renowned falls in the area. It is named for the rainbows which form during the early morning due to mist.
