El Islote Reef Cozumel Dive Site
El Islote — Advanced Cozumel Southern Reef Diving
El Islote is an advanced-level dive site located near the southern tip of Cozumel, close to the Punta Celarain lighthouse. The site features a large patch coral formation that begins shallow and gradually slopes deeper. Access is highly condition-dependent, as boats can only reach the area when wind and sea state allow safe passage around the island’s southern end. Currents can be unpredictable, making this site suitable only for experienced divers.
