Giardini Poseidon Terme
The largest spa on the island has the added boon of a natural sauna hollowed out of the rocks. Here you can sit like a Roman senator on stone chairs recessed in the rock and let the hot water cascade over you. With countless thermally regulated pools, promenades, and steam pools, plus lots of kitschy toga-clad statues of the Caesars, Poseidon exerts a special pull on tourists, many of them grandparents shepherding grandchildren. On certain days, the place is overrun with people, so be prepared for crowds and wailing babies.
