Thermal Valley 地熱谷

Anchor point


Located beside Beitou Hot Spring Park, Thermal Valley is one of the sources supplying the area’s hot springs. The sulfuric steam that blankets the valley year-round gives the valley a frightening quality, giving rise to nicknames like “Ghost Lake.” The springs here have the highest temperatures of any in the Datunshan volcano group. With its surreal sulfuric atmosphere, it’s no wonder Thermal Valley was considered one of the “12 great sights of Taiwan” during the Period of Japanese Occupation!

The “Beitou rocks” (aka Hokutolite or Anglesobarite) in Thermal Valley contain the radioactive element radium. Out of the many thousands of minerals existing in the world, they are the only ones named after a place in Taiwan, and can be found in only two places: Beitou and Tamagawa, Japan. In recent years, the “Beitou Rock Conservation Area” has been established to ensure the protection of these natural rarities. Thus, when visiting Thermal Valley, you not only get to experience “hell” but also gain insight into some rare radioactive rocks!

Water temperature in Thermal Valley’s hot springs ranges from 80-100℃. The sodium carbonate springs tend to be corrosive, and have come to be known as “Green sulfur springs” and “Sulfur heads.” Visitors used to boil eggs in the hot springs, but the practice has since been prohibited—not only to protect the water quality but to keep tourists from falling in and boiling themselves!

    A typical thermal hot spring


    The Beitou Hot Springs is a green pond full of acidic water from a thermal hot spring. Not exactly the place you want to be on a hot, humid August afternoon! If you've been to Yellowstone, Lassen, Hawaii, Iceland or other places with geothermal springs, this one was not particularly impressive. The 2 unique features are a small waterfall and a Taoist temple next to the pond. If you want to soak, the thermal baths are down the road. This pond is for looking only (unless you want to get dissolved and cooked).

    Not that special


    Thermal Valley is situated in the Beitou Hot Springs area. It wasn't that impressive, but it was just a good landmark to walk through.

    green sulfur


    it has green sulfur. it’s a pool with lots of smoke. not much to see in my opinion, but it’s ok to visit since it’s about 15mins walk away from beitou train station and there are places to go nearby hot spring museum, library

    Must do while in Beitou


    This is a small park (free entrance) where one can have a close look at one of the sulphuric hot spring sources in Beitou - am emerald-green lake from which sulphuric steams are emanating. The valley is 15min walk from Beitou train station and the visit will only take you 20min. But in my opinion the best sighting you can have of the hot springs in their natural environment.

    Green with Sulphur


    This is a relatively small lake that has been turned green due to volcanic gases and sulphur. It’s steaming and would be pretty awe inspiring at first light. Even in the early afternoon of a rainy day when we saw it, it was still pretty cool. It doesn’t smell as much as other volcanic pools do, so don’t worry about that! It’s easily walkable from the metro station too!
