Half Moon Caye Wall

Half Moon Caye Wall is the dive that redeems any Blue Hole skeptic's day. The shelf before the drop is a garden-eel plain — hundreds of slender bodies swaying and vanishing as you glide over — and the lip beyond erupts in tube sponges, sea fans, and plate corals fed by clean oceanic water. Spotted eagle rays patrol the face, turtles bulldoze through the shallows, and groupers loiter at cleaning stations. Topside, the caye's red-footed booby colony wheels overhead during the surface interval. Many Belize regulars quietly rank this above its famous neighbor.

その瞬間のために: Garden-eel flats, a sheer sponge-clad wall, eagle rays and turtles, booby colony at the surface interval.

地形: A white-sand shelf pocked with coral heads, ending at a wall lip that drops sheer into deep blue.

流れ（カレント）: Generally gentle along the wall; more movement on the exposed corner.

エントリー: Moored entries over a sandy shelf on Lighthouse Reef's southeast corner, usually paired with the Blue Hole day.

危険生物・リスク: Depth temptation over the lip; keep the plan multilevel.

保全: Part of the Half Moon Caye Natural Monument; moorings only, and the caye itself is a protected seabird nesting site.
