Beitou Hot Springs Thermal Valley

Witness the constantly steaming, sulfuric lake with its unique radium-infused green tint, a rare natural wonder.

In their own words: “Next on the list is Beitou District. Just a short trip from the city, this area is famous for its natural hot springs and relaxing bath house, but you have to visit the thermal valley. It's a sulfuric lake that's constantly steaming, earning it the nickname Hell Valley. Uniquely, this green tint in the water comes from traces of radium. Yes, it's actually a little radioactive and can only be found in two places on Earth: Japan and right here in Beitou.”
