Chumphon Pinnacle

Chumphon is Koh Tao's serious dive, the one instructors save for the last day of an Advanced course. A granite tower rises from the gulf floor to 14 m, its entire crown carpeted in magnificent sea anemones that ripple like a single organism, pink skunk clownfish seething across it. Around and above, the water column belongs to schools: big-eye trevally in torrents, chevron barracuda in drifting palisades, queenfish flashing through. Whale sharks appear regularly enough in season that half the island drops everything when the call goes out. The resident bull sharks that once patrolled here faded from sightings in the mid-2010s; the pinnacle never needed them to fill a logbook page.

您此行的高光时刻: Anemone-carpeted summit, torrents of trevally and barracuda, the island's best whale-shark odds

地形地貌: Granite pinnacle crowned in anemones, satellite rocks on sand at 36 m

水流: Open-gulf site with honest current some days; descents and ascents use the lines.

入水方式: About 30-45 minutes northwest of the island; buoy lines run to the pinnacle top at around 14 m.

危险因素: Depth for newer divers, current on exchange days, and crowds on the lines at peak hours.

保育: Multiple schools converge here daily; line courtesy and controlled ascents keep the column safe for everyone.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
