雙峰藍洞

簡介

📍 概況：後壁湖外海極具魅力的進階地形船潛點，以兩座水下巨峰間夾峙的海底穿透隧道著稱。 🤿 環境：水深 11-30m，兩座礁峰底部夾有一條長約 10 米的天然海蝕隧道，頂部透光迷人。 🐠 生態：隧道口外生長大型海扇，洞內聚集大量擬金眼鯛與玻璃魚，外圍常有海龜與魟魚巡航。 ⚠️ 須知：穿越隧道時需嚴格控制中性浮力與管線配置，避免碰撞頂部岩石或揚起底部沉積物。

📍 Overview: Attractive advanced cavern boat dive off Houbihu, famed for a 10m submarine tunnel between twin pinnacles. 🤿 Conditions: 11-30m deep. Natural sea cavern tunnel running through rock pinnacles with dramatic light penetration. 🐠 Ecology: Tunnel entrances framed by giant sea fans; interior packed with glassy sweepers, with cruising turtles outside. ⚠️ Note: Strict neutral buoyancy required inside overhead swim-throughs to prevent ceiling collisions and silting.
