A 
hot spring is a spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust.
How to map
Map the hot water vent(s), a node for small ones or an area for larger vents and add natural=.
If there is a significant pool of water at the spring(s), map it as area with natural=water, this area would typically overlap the vent(s).
Use water_characteristic=* to specify mineral, gas or other content, this can be attached to particular vents and/or water pools.
This tag is strictly for mapping the natural source of a hot spring, not any recreational aspect of it. For man made pools or baths heated by a hot spring, see amenity=public_bath and Swimming and bathing#Public bath.
Note: If it is producing hot water, use natural=. If it is only producing steam, use natural=fumarole.
