Trinity Caves

Trinity Caves is West Bay's architecture dive. Three sand-floored ravines run seaward under bridges of coral, deep and narrow enough to feel like hallways, then deliver you through arches onto the open wall at twenty meters — a doorway moment divers replay on the boat afterward. Sea fans crowd the ravine rims, groupers and filefish idle in the shade, and the sponge growth thickens the moment you clear the wall lip. It is the approachable version of the canyon-and-arch terrain that defines Cayman's best wall diving, minutes from the busiest beach on the island.

您此行的高光时刻: Ravine-and-arch passages, the doorway exit onto the wall, classic West Bay convenience.

地形地貌: Three parallel ravines — more canyon than cave — winding through the reef crown to openings on the wall face.

入水方式: Moored West Bay site minutes from Seven Mile Beach operators.

危险因素: Semi-enclosed passages concentrate careless fins; watch depth at the wall exits.

保育: Mooring-only marine-park site under heavy daily use.

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）。
