The Gemma is just a quarter of mile away from the "Castiglione" Thermal Park, a stunning array of swimming pools of various kinds, a private beach and natural saunas, all overlooking the beauty of the gulf'plus (!) health treatments with Ischia's miraculous thermal water and curative muds. Guests of the Gemma who spend at least one week with us enjoy free entrance to the Castiglione park. All other guests will have a 20% discount on the price of admission.
