Finally due to reopen to the public in 2015 after a protracted refurbishment, the Balneario bathing complex's thermal waters of 30°C to 40°C are used to treat all manner of muscular and skin afflictions. The sulfurous waters of these mineral springs are potent and immersions of only 20 minutes per day are allowed. Mud from the Río San Diego is also used here for revitalizing mud baths.
Other health services include massage and a 15-day course of acupuncture; don't expect fluffy towels and complimentary cups of coffee. The Balneario San Diego is more like a Moroccan hammam than a five-star hotel facility, though it's perennially popular with Cubans undergoing courses of medical treatment, plus the odd curious tourist.
If you're looking for cold water, you can swim at the Hotel Mirador pool .
