Which Should You Visit?
Both islands promise turquoise waters and laid-back vibes, but they deliver fundamentally different experiences. Cozumel operates as Mexico's premier diving destination, where the underwater world takes precedence over nightlife. The island splits between cruise passenger crowds at the port and serious divers heading to Palancar Reef. Tacos cost $2, cenotes offer freshwater swimming, and the peso stretches further than dollars. Key West functions as America's tropical experiment, a place where literary history meets tiki culture. Mallory Square's sunset celebration defines the rhythm here, while Duval Street offers craft cocktails at craft prices. The Hemingway House and Southernmost Point anchor tourist circuits that Cozumel lacks. Where Cozumel prioritizes underwater exploration with limited cultural attractions, Key West balances beach relaxation with historical sites and established nightlife. Your choice depends on whether you want to spend more time below the surface or above it.
