Mary's Place

Mary's Place is Roatan's signature dive because nothing else on the island feels like it. The reef here split along deep cracks, and the dive threads them in single file — walls close enough to touch (you must not), the sky reduced to a bright seam far overhead, the shadow growth worth searching slowly for small life. Corners open into rooms, then squeeze again, before the fissure releases you onto the open wall. Buoyancy is the entry fee: the site was rested for years after fin damage, and guides enforce trim like proctors. Book it early in the week; weather cancellations are common.

您此行的高光时刻: Single-file crevice passages, black coral and sponge-lined walls, a genuinely unique reef structure.

地形地貌: Deep tectonic fissures slicing through the reef shelf, their walls carpeted in sponge and black coral, opening onto the outer drop.

水流: Usually calm inside the cracks; surge can funnel through in swell.

入水方式: Moored site on the south shore; groups drop onto the reef shoulder and enter the crevices single file.

危险因素: Confined passages with surge; not for divers who cannot hold position without hands.

保育: Previously closed to recover from diver damage; strict group sizes and no-contact rules keep it open now.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
