The island of Ischia is the largest of the islands in the Gulf of Naples and offers a wide variety of accommodation and holiday opportunities: although it has an area of only about 47 square kilometres, there are six different municipalities with different administrations: Forio, Ischia, Lacco Ameno, Casamicciola, Serrara Fontana and Barano.

The village of Sant'Angelo is part of the municipality of Serrara Fontana, which includes both part of the island's only mountain, Mount Epomeo, and an outlet to the sea with the promontory of Sant'Angelo.
