Hotel with a heated pool in Saturnia

The pool. Outdoor pools fed by the hotel's private spring, at around 37 °C, plus a hot tub using the same water.

The hot tub. Thermal-water hot tub.

The Oyster guide says the water keeps its natural temperature, so you can swim year-round. On HotelsCombined, one guest enjoyed this guests-only thermal pool; another mentions the smell of sulphur.

Guide's tip. Depending on the season, insects can be a nuisance by the pool: bring repellent.

The pool. Large outdoor pool of sulphurous thermal water, which gushes out at a constant 37.5 °C and naturally renews itself within a few hours.

A Stylist journalist who spent three days there describes water at 37.5 °C and a deeply relaxing swim. On Expedia, guests find the thermal pool fantastic; some warn that the smell of sulphur takes you by surprise when you arrive.

Guide's tip. Take off your jewellery before swimming: the sulphurous water can tarnish it.

The hot tub. Seasonal outdoor pool (heating not specified); hot tub listed among the facilities.

One guest found the pool clean and refreshing, without mentioning heating.

Guide's tip. For warm water, combine your stay with the nearby Saturnia hot springs.
