This natural hot spring sits inside Premier Hotel-CABIN Sapporo, a short walk from Susukino Station. Its brown, high-salinity spring water is drawn from about one kilometer underground, and the facility also has a sauna and a rooftop open-air bath. Non-guests can use it as well, entering through the reception desk on the basement first floor and taking the stairs up to the rooftop bath. The fee is high for the facilities provided.
