A natural swimming pool cut into the limestone of the Delimara peninsula, about ten minutes' drive south-east of Marsaxlokk village. The water is deep, clear, and the sea has worn the rock platforms around the pool into smooth ledges that act as natural diving boards. There is no sand, no beach bar, no shade — just the rocks, the water, and (in summer) plenty of company.
Park at the end of the road on the headland and follow the path down. Reef shoes are a good idea, and bring everything you'll need — water, sun cream, food. The pool is exposed in rough weather; on calm days the snorkelling along the cliff base is excellent. Some boat tours from the village stop here in summer.
