Las Caletillas y la Candelaria
Candelaria, or La Arena, beach is opposite the cathedral; it is a broad, black sand beach, but you must be careful of the current and the undertow. It is advisable to stay near the edge.
El Charquito is the next beach along, near the fishing docks. This is much safer. There are many different fish and shell-fish restaurants close to the beaches.
Las Arenitas beach, next to the avenue going towards Candelaria you should also be careful on this beach when it is rough.
All these beaches get quite crowded in summer.
