Dive-site story
Situated along the southwestern edge of Cozumel inside the marine park, Columbia Reef features massive coral pinnacles rising from sandy channels and a sheer drop-off into deep blue water. Divers glide along towering spurred formations punctuated by tunnels, caverns, and deep swim-throughs before finishing their drift over shallower coral gardens.
Monolithic coral pinnacles and towering buttress structures
Network of arches, tunnels, and dramatic swim-throughs
Frequent encounters with sea turtles feeding along the reef crest
Expansive drift diving over white sand flats and deep reef slopes
