Officially the water is classed as chloride spring, sulfate spring and sulfur spring. Its sources put out around 432,000 litres a minute. 1 inns take visitors here.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Clear water with a faintly bitter taste. Known for holding heat.
The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.

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.
