The Beitou area of Taipei is renowned for its high concentration of thermal spa centres. There are establishments to fit any budget, from the low-priced open-air Public Hot Spring (modest swimwear required) to private hotels and resorts uphill, all offering hot spring baths at various price points. One option most resorts offer is renting a private room with a large bath that can be filled with hot spring water. The Spring City Resort in Beitou is a great mid-range option. A session here includes access to about a dozen thermal pools of varying water temperature (from seemingly boiling-hot to rather chilly), plus robe, towel, and slipper rental. They even offer a free shuttle bus to the metro station. For a luxurious spa treatment, look into the offerings of Hotel Regent Taipei, for example. Wellspring Spa offers a wide range of relaxing treatments including massages, body wraps, skin polishing and facials. Take the elevator to the top floor and unwind at this urban sanctuary.
