Satonomori Tennenn Onsentang is a day-use natural hot spring on the outskirts of Sapporo, a walk from Kaminonporo Station. Its slippery salt-rich water is brown, the color of cola, and it feeds an open-air bath. The large bathing area holds a 41-degree open-air bath, a 40-degree warm bath, a 42-degree hot bath, a 15-degree cold bath, and a sauna. The changing room has no lotion, so bring your own.
