SeaAbout
This is a small, town-run day-use bath on a hill above the coast road south of Mashike, with just one indoor tub and one open-air tub, both split by gender. There is no sauna and no cold plunge. A screen along the road blocks a full ocean view from the open-air bath, but part of it looks out over the water through an acrylic panel, and the bath is especially known for sunset. The spring water is a simple, mildly acidic type that locals have long used for skin complaints. Reviewers note the facility, though unrenovated, is kept unusually clean for its size. The on-site restaurant is currently closed with no reopening date.
