Chankanaab Reef
A beginner-friendly shore dive within Chankanaab National Park, combining easy coral reef access with a certified-diver cave entrance — the only shore-accessible cave dive in Cozumel.
Overview
Chankanaab Reef fronts the protected national park of the same name at kilometre 9 on Cozumel’s southern coast, offering easy shore entry directly into crystal-clear water teeming with parrotfish, angelfish, spotted drum, and long-snout seahorses in 5–12 metres. A mild northward current keeps the water refreshed and visibility consistently excellent, and for certified divers the submerged cave La Quebrada — the only shore-accessible cave dive in Cozumel — is a highlight accessed through a halocline where cool freshwater meets the sea.

Marine Life
Long-snout seahorses, spotted drum, and parrotfish are common throughout the shallow reef, and green and hawksbill turtles rest on the coral heads with regularity. The splendid toadfish — endemic to Cozumel — can sometimes be found in reef crevices near the national park, and the submerged cave La Quebrada shelters glassy sweepers, lobsters, and moray eels in its halocline-rich interior.
