On the island of Cozumel, 12 miles off the Yucatán Peninsula, you can still
horseback ride in the bush, explore Maya ruins at San Gervasio, snorkel at
Chankanaab Park, and swim off any number of lovely beaches. And Cozumel's
main stage is the current-swept leeward western shore, a cornucopia of
teeming marine life, coral gardens, coral pinnacles and fall-away vertical
walls — no surprise given that the Yucatán Peninsula and Cozumel are
separated by a channel nearly a half-mile deep.
