Sulfate spring

Sulfur spring
The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.

With tattoos
Many public baths still turn away visible tattoos, and the rule is set by each bath, not by the town. The reliable way round it is to bathe privately: a room with its own open-air bath, or an inn with a private bath you can book for yourselves.
