大藍洞

簡介

📍 概況：聞名全球的世界自然遺產，一個直徑超過 300 米、深達 124 米的深邃藍色水下沉洞，是無數潛水員的終極夢想。 🤿 環境：水深 40m (休閒潛水極限)。潛水員將會下潛至 40 米深處，穿梭於冰河時期遺留下來的巨大石灰岩鐘乳石柱之間。 🐠 生態：洞內光線幽暗且缺乏珊瑚，主要以觀賞壯麗的地質奇觀為主，偶爾會有巨大的加勒比礁鯊 (Caribbean Reef Sharks) 從深處巡游而上。 ⚠️ 須知：這是一個典型的大深度無底洞潛水，免減壓時間 (NDL) 通常只有短短幾分鐘。必須具備 AOW 以上資格，並擁有極佳的懸浮與中性浮力控制能力。

📍 Overview: A world-renowned UNESCO World Heritage site. A massive underwater sinkhole over 300m wide and 124m deep, a bucket-list dive for many. 🤿 Conditions: 40m deep (recreational limit). Divers descend to 40m to weave through massive limestone stalactites formed during the last ice age. 🐠 Ecology: The cavern is dark and lacks coral; the draw is the geological majesty. Large Caribbean Reef Sharks are occasionally seen rising from the abyss. ⚠️ Note: A classic deep dive over a bottomless void with very short NDLs. Requires Advanced certification and absolute mastery of neutral buoyancy.
