Alejandros Reef
Xcalak, Quintana Roo, Mexico

The reefs off Xcalak village in the far south of the Riviera Maya are far less-visited than in the busy north, which means better coral and fewer boats. Alejandro’s is an easy horseshoe-shaped reef with great coral and abundant morays – which are hard to see in the north.
