Kagaya (北投日勝生加賀屋) sells day entry to its fourth-floor white-sulphur public bath in Beitou from 7 am to 11 pm. The men's and women's nude baths swap daily between two sides, one with a dry sauna (望月) and one with a steam room (遠山), so each day brings one or the other. Entry is NT$1,200 on weekdays or NT$1,500 at weekends plus 10% for up to four hours, and a private Beitou-stone bedrock sauna (岩盤浴) for two is bookable separately.
