Valparaíso Aguas Termales

Valparaíso is a public thermal spa with a real wood-lined sauna alongside its mineral-water pools and Jacuzzi. Its operator advertises general admission and an adults-only sauna area; recent venue posts say a two-hour general entry includes the sauna. Reserve or check the current entry price before travelling. The photo shows the actual sauna room.
