Relax in the Poseidon Gardens Thermal Spa, the oldest and largest thermal park on the island of Ischia. Enjoy the natural beauty of the park, with 15 thermal pools, 3 sea-water pools, a Japanese bath, a natural sauna, and a wellness center.

Located in the municipality of Forio, nestled in the beautiful Citara Bay, the area of greatest hydrothermal interest on the island due to its boiling and highly therapeutic springs. Just as the concept of a thermal park on Ischia is unique, the island is particularly rich and fortunate: an extraordinary combination of miraculous thermal waters, nature, sea, climate, light, and flavors.

Poseidon Gardens Thermal Spa encompasses 60,000 square meters of lush vegetation featuring 15 thermal pools with temperatures ranging from 28° to 40°C, 3 sea-water pools, a Japanese bath, a natural sauna, three restaurants, a wellness center, a long beach lapped by crystal-clear waters, relaxation areas, a shop selling branded clothing, as well as essential services such as changing rooms and restrooms scattered throughout.

Among the various thermal baths, there are four Kneipp groups, consisting of adjacent hot (40°C) and cold (15°C) baths for alternating immersion. The Kneipp therapies also include the so-called Japanese Bath, a path divided into a hot section at 40°C and a cold section at 15°C, with a bottom covered in small stones to walk on for reactivating the circulatory system.

The relaxing and purifying Natural Sauna, carved into a cave entirely hewn from rock, features warm steam emitted from a thermal water spring reaching 85°C, creating a special warm-humid microclimate inside the cave, ideal for alleviating numerous disorders through.
