Today, Isla Mujeres is a bohemian outpost amidst the hustle and bustle of the Caribbean. Isla's big draw is its beaches and calm, jewel-like waters that fade from fluorescent lime green at Playa Norte to pale turquoise at the very snorkelable Garrafon reef. Isla Mujeres is 15 minutes by boat northeast of Cancun across the multi-hued Bahia de Mujeres. Just five miles long and less than a mile wide, it's an ideal reconnoiter by bicycle.
