Xinbeitou’s springs come in a few distinct styles, and picking the right one shapes your whole visit. At the budget end are the large public hot-spring pools in Beitou Park, which are inexpensive and communal—usually swimsuit-required, mixed-gender, and a sociable, local experience. At the comfort end are the hot-spring hotels and resorts, many of which sell day passes that let you use their pools and facilities without staying the night; these are the easy, towel-provided option if you just want to relax.
In between sit the private rooms many hotels and bathhouses rent by the hour—ideal for couples or anyone who prefers privacy to a shared pool. The waters here are naturally heated by the volcanic activity of nearby Yangmingshan and have been prized since the Japanese colonial era, when Beitou became Taiwan’s premier hot-spring resort. Whatever you choose, check the venue’s rules in advance: requirements around swimsuits, single-sex versus mixed bathing, tattoos, and time limits vary from place to place, so a quick look at the official details saves any surprises at the door.
