A thermal spa created in the 19th century and built on a cliff overlooking the beach, this is the best place in town to "take the waters." The old-fashioned jewel lies a short distance west of Vico off the main road to Sorrento (the SS 145) and offers a wide range of treatments and therapies (fees start at 24€). The public spaces overlook the shore in a cascade of terraces, and the spa has a delightful ambience. You can swim off the private beach where the sulfur spring flows into the sea, creating a mineral mix with unique healing properties. The charming restaurant is housed in a Liberty-style (Italian Art Nouveau) hall, with a bar and attached terrace affording beautiful views over the sea. There are also seven bright and well-furnished guest rooms (150€-220€ double, including breakfast and access to the spa).
