La Pared — "The Wall" — is the reason La Parguera is on the diving map. About five kilometres offshore the reef shelf ends abruptly, dropping more than 500 metres into the open Caribbean. The wall is covered in black coral, gorgonians and sponges, and the deep water brings turtles, eagle rays, reef sharks and the occasional pelagic past.
Dive operators in the village run two-tank trips out most mornings; the dive itself is intermediate or better, with strong currents possible. There are also shallower sites along the cay reefs that are fine for beginners and snorkellers. Visibility is typically best in winter and spring.
