Caleta de Fuste, also known as El Castillo, is a modern, purpose-built resort with shops, restaurants, cafes and bars. There is also large, modern shopping centre, a little way out of town, with a cinema, a bowling alley and restaurants with sea views.

The castle (martello tower) that gives El Castillo its name was built in 1743 by a military engineer, Claudio de Lisne, and is situated in the busy harbour area.

Because the beach is safe and the waters of the bay are calm and shallow Caleta is a popular choice with families. Water sports enthusiasts are also well catered for and facilities include windsurfing, scuba-diving and sailing. Golfers can enjoy two golf courses close by (one of which has hosted the Spanish Open).
