Colombia Wall

Colombia is Cozumel at its most architectural. Coral pinnacles the size of buildings stand along the drop-off, and the dive threads the ravines between them — one moment enclosed by walls of plate coral and sponge, the next hanging over open blue. Eagle rays and turtles work the tops in winter; barracuda hold midwater like fixed hardware. Because the structure spans a wide depth range, guides can run the same terrain deep and bold or shallow and easy, which is why half the island's boats seem to end up here on any given morning.

您此行的高光时刻: Skyscraper pinnacles, ravine swim-throughs, turtles and eagle rays, flexible depth profile.

地形地貌: Massive coral pinnacles and ridges standing proud of the wall edge, cut by ravines and sand slides.

水流: Steady southern-park current; occasionally strong enough that guides reroute to shallower Colombia sections.

入水方式: Southern-park site with a longer boat run; drift entries onto the pinnacle field.

危险因素: Depth along the outer edge and current on the exposed corners.

保育: Marine-park rules; the shallow Colombia Gardens section absorbs snorkel and novice traffic instead.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
