Cala Bassa is one of the finest beaches on Ibiza — a broad arc of white sand backed by pines, about 10 km southwest of San Antonio by road (or accessible by boat from the port, which is the better option in summer when the road is clogged). The water is an almost improbable shade of turquoise, sheltered from the open sea by rocky headlands on either side.
The Cala Bassa Beach Club operates on the beach, offering sunbeds, food, and drinks at resort prices — but the club does not take over the entire beach, and there is still free sand to spread out on. In high season a water taxi runs from San Antonio port every half hour, making this an easy day trip without a car. The combination of reliable calm water, easy access, and pine shade makes Cala Bassa the most consistently enjoyable beach in the San Antonio area.
