泰国洞穴潜水：攀牙府Ko Haa内部的教堂式潜水通道

ter cavern diving and marine ecotourism converge at The Cathedral, Ko Haa Yai, where a sculpted swim-through opening floods the dark limestone interior with turquoise Andaman Sea light. Hollowed by centuries of karst dissolution, the entrance sits at approximately 14 metres depth. Divers can ascend inside the rock vault and breathe the trapped air pocket above the waterline, a feature unique to this celebrated dive site. 4K, horizontal, wide angle, handheld, scuba diver POV.
