Site details

On the south side of Half Moon Caye, the reef crest sits in about 6m of sandy garden before plunging as a sheer wall draped in sponges, gorgonians and black coral into the deep blue. Sand chutes and coral spurs funnel divers over the lip, where eagle rays, turtles and reef sharks cruise the drop-off. Many divers rate it the single best wall dive in Belize for its consistent visibility and abundant life.
