With its 18 miles of beaches, bays and inlets, Ischia has sometimes been called "the Garden of Europe" and offers a variety of excursions for nature lovers in search of as yet unpolluted areas, reserving some exciting moments for snorkelling and diving enthusiasts. 37 kilometres of coast to enjoy the sea in strips of sand and beaches coloured with smooth pebbles, where bathing is a relaxing moment to share with friends amd family. Corners of paradise where seawater mingles with hot spring water that gushes out just a short distance from the shore. In secret places accessible by boat, the silence is broken only by the distant cries of seagulls.
Golden beaches, bays and creeks overlook a transparent sea that ranges from a clear blue to a turquoise-green. Most of them can be reached on foot, such as the enchanting two kilometres of the shore of Maronti, where the hot springs of Olmitello and Cavascura emerge; Citara and San Francesco with their splendid coast, Cartaromana, where rocks overlook a sunken Roman port, Cava dell'Isola, a spot that is a favourite with the youth, and the little magical bay of San Montano. While the beauty of other beaches, such as that of San Pancrazio or the "Scarrupata", as well as the "Magician's Cave" is only reserved for those who are willing to reach them from the sea, even in the middle of winter as hot springs heat the shoreline of the Bay of Sorgeto.
The sea hosts various species of cetaceans and it is often possible to enjoy the company of merry dolphins during a boat trip. Neptune's Kingdom Marine Park was founded to safeguard this precious stretch of sea, rich in many rare species.
