The experience

It is also a full-service day spa with private mineral baths, massages, wraps, and a salon. Reservations are required for all services and cave access.

The honest take
What to love. What to consider.
The highlights
- Truly unique: the only natural underground vapor caves in North America, with a 130+ year history
- Full-service spa — private mineral baths, massages, body wraps, and salon in one building
- A quiet, meditative experience (it is a designated quiet space), very different from the big public pools
Keep in mind
- The caves are small and can feel claustrophobic or too hot/humid for some people
- Locker rooms and facilities are small for a historic building — it feels cramped at busy times
- No large soaking pools — if you want traditional pool soaking, this is not the place
