Blue Channel

Blue Channel is a shallow adventure playground: a crooked lane of sand walled by coral, ducking under arches and past little cavelets on its way out toward the reef edge. The enclosed feel concentrates life: squirrelfish and glassy sweepers pack the overhangs, a resident green moray works the crevices, and spotted drums flutter in the undercuts like dropped ribbons. Because it tops out near five meters, it doubles as a superb night dive and a long, unhurried second tank. Local divemasters treat it as the island's best odds for finding toadfish and octopus on one dive.

اللحظة التي جئت من أجلها: Coral arches and cavelets, dense overhang life, first-rate night diving in easy depth.

التضاريس: A winding sand-floored channel cut through the shallow reef flat, roofed in places by coral arches.

نقطة الدخول: Just off West End; also reachable as an ambitious shore dive from some beaches.

المخاطر: Mild surge through the arches on swell days.

الحفاظ على البيئة البحرية: Marine-park waters; the swim-throughs are fragile: go single file and touch nothing.
