Ischia
Hot springs lured ancient Greeks and Romans to the Bay of Naples island of Ischia - one of the best islands in Italy, and travelers have enjoyed its beaches and rich gardens ever since. Head to Spiaggia Citara, where the exquisite grounds of a high-end thermal treatment overlook the shore, to locate all three. Alternatively, three open-air hot baths are accessible from the three-kilometer beach at Spiaggia dei Maronti, near the southern settlement of Sant'Angelo.
In the summer, expect busy beaches, or take a boat taxi to one of the hidden coves. From Forio on the west coast, you may visit Giardini Ravino, which has succulents and cactus, or the spectacular La Mortella, which was designed by Susana Walton and British musician Sir William Walton.
You may take a ferry from Naples to Ischia, and then from either Naples or Ischia to the smaller – and less busy – island of Procida.
