Grenada · Carriacou (Tyrrel Bay)
Deep wall dive at the Sisters Rocks.
Deep wall dive at the Sisters Rocks.
Boat-access deep rocky site between the Sisters Rocks, with a steep wall, gorgonian cover, and a strong marine-life profile. It suits experienced divers who want a classic Caribbean deep-wall dive with wide relief, busy fish life, and the chance of larger pelagic visitors when the water is settled and the visibility is good.
