聖約翰礁群

簡介

📍 概況：位於紅海極南端的一組原始礁石群，以錯綜複雜的洞穴 (Caves) 網絡聞名。 🤿 環境：水深 5-30m，迷宮般的天然隧道與洞穴穿透整個礁石，光影如幻。 🐠 生態：洞內常見隆頭鸚哥魚睡覺，外牆覆蓋著未受破壞的原始珊瑚。 ⚠️ 須知：在隧道中穿梭需極佳的浮力控制，避免揚沙，並小心頭頂的銳利岩石。

📍 Overview: A pristine group of reefs in the deep south, famous for a complex network of caverns and swim-throughs. 🤿 Conditions: 5-30m deep. Maze-like natural tunnels pierce the reef, creating magical light effects. 🐠 Ecology: Bumphead parrotfish often sleep in the caves. The outer walls boast untouched, pristine corals. ⚠️ Note: Navigating the tunnels requires excellent buoyancy to avoid silt-outs and head bumps on sharp rocks.
