The pristine waters around María La Gorda are widely regarded as among the best for diving in the whole of Cuba, protected by the bay and spectacularly calm and clear, averaging 25m in depth. Diving here is enhanced by a quick drop in water depth, with a large number of the fifty-odd dive sites only ten to twenty minutes by boat from the shore, while the spectacular variety of fish life here includes barracuda, moray eels, several species of rays, lobsters, whale sharks and more. Among the specific dive sites of note are Ancla del Pirata, featuring an two-ton eighteenth-century anchor covered in coral; colourful Paraiso Perdito, which reaches depths of 33m and is particularly abundant in coral and fish life; and Yemayá, a 2m-high cave at 32m deep, which ascends almost 20m through a long, gently curving, mysterious tunnel.
Several boat trips are offered at the marina too. You can opt for an all-day excursion, which is aimed at couples and includes an on-board dinner. The club also runs fishing trips for a minimum of four people.
