Sail Rock

Sail Rock stands alone in the middle of the gulf, a granite sail above water and a fish magnet below it, widely rated the best dive in the Gulf of Thailand. Its party trick is the Chimney, a vertical shaft through the rock that divers enter near 18 m and exit around 6, rising through a tube of stone with fish flickering past the openings. Outside, the monolith disappears under snapper, fusiliers, and big-eye trevally so dense they behave like weather, with queenfish and king mackerel raiding the edges and whale sharks calling unannounced. Batfish follow divers around like hired guides.

اللحظة التي جئت من أجلها: The Chimney swim-through, bait-ball density on a lone monolith, regular whale-shark cameos

التضاريس: Granite monolith rising from around 30-34 m to above the surface

نقطة الدخول: Roughly midway toward Koh Phangan and dived by boats from Koh Tao, Phangan, and Samui; expect company.

المخاطر: An overhead shaft with two-way traffic, mid-sea exposure, and busy surface conditions.

الحفاظ على البيئة البحرية: Heavy multi-island boat traffic; moorings, not anchors, and patience at the Chimney entrances.

نيتروكس: يستحق الأمر هنا: الملفات الشخصية تقع في النطاق الذي يُمدّد فيه الهواء المدعّم (نيتروكس) وقت الغوص دون توقف تمديدًا ملموسًا، مع التدريب اللازم لاستخدامه.
