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.

Sanxia Old Street is one of the most well reserved historic streets in Taiwan, one that's about 200 metres long. This is a great place to stroll around, and one where you can admire the old street-houses with Taiwanese traditional architecture. It is also one of the most visited places in Taipei during the weekends.
