Beitou is a volcanic district in northern Taipei where the air smells faintly of sulfur and steam rises from the gutters. It was developed as a spa resort area during the Japanese colonial period. You can visit the "Thermal Valley," a bubbling sulfuric lake, and then head to a private bathhouse or the public open-air pools for a soak.
Beyond the water, the area is home to the Beitou Library (a stunning eco-friendly wooden building) and the Hot Spring Museum. It feels like a quick trip to rural Japan without ever leaving the Taipei MRT system.
One fun fact people love:
The Thermal Valley is often called "Hell Valley" because the water temperature can reach 90°C (194°F), creating a constant, eerie shroud of green-tinted steam.
Where in Taipei is it?
Accessible via the Xinbeitou MRT Station (a branch off the Red Line).
Things nobody tells you:
In the public pools, you must wear a proper swimming suit (no board shorts for men; must be tight-fitting), and swimming caps are mandatory. If you want a more relaxed experience, book a private room in a hotel.
