Ischia is a volcanic island in the Tyrrhenian Sea, at the northern end of the Gulf of Naples. Some sights worth seeing are the Church of Soccorso (a tiny white-washed church located in the square on the Punta del Soccorso in Forio, that looks out onto the crystal clear sea), and Castello Aragonese (a castle located on a small island near Ischia Ponte). There are many wonderful beaches located here as well, namely Lido di Ischia and Cartaromana beach.
