Thermas Hotel Mossoró

Thermas Hotel is Mossoró's best-known hotel, a resort built around natural hot-spring pools that has been running since 1979. Its official site says room rates include the Planeta Água thermal water park, which also sells day passes to locals, so expect families at weekends. The grounds cover about 200,000 m², roughly ten minutes from the centre. Booking sites list around 145 air-conditioned rooms with balconies, three restaurants and a dozen outdoor pools. It's a mainstream family resort, not a gay venue.
