Hells in Beppu are rather colorful

 

Beppu's top attraction is touring the eight hells. The hells are in fact multicolored volcanic pits of boiling water and mud and one geyser. They are too hot to be diluted into onsen, and they emerge at temperatures ranging from 50 to 99.5 °C (122 to 210 °F). Some of the hells have a natural smell of sulfur — which comes out a bit like rotten eggs. See some of the hellish photos.
