El Tunel

El Tunel is a reef dive site located at Punta Cancún, outside the bay, in the Cancún area of Mexico. It sits among a group of reefs offering coral formations and marine life, and falls within the National Marine Park. The maximum depth reaches 17 metres (56 ft), with the working depth range running 15–17 metres (50–56 ft), making it one of the more engaging sites along this stretch of coast.

The reef features beautiful coral formations typical of the Punta Cancún reefs, providing structure for a wide variety of marine life. Divers can expect to encounter sea turtles, eagle rays, nurse sharks, reef sharks, green moray eels, barracuda, lobsters, and crabs among the reef communities.

Access is by boat, with the site reached as part of a two-tank dive pairing with another Cancún reef. Water temperature stays warm year-round, ranging from 24–26 °C in winter and rising to 27–28 °C in summer. Visibility is great, and current is medium at this site.
