Isla Mujeres (Island of Women) is a casual, laid-back refuge from the conspicuously commercialized action of Cancún, visible across a narrow channel. It's known as the best value in the Caribbean, assuming that you favor an easy-going vacation pace and prefer simplicity to pretense.
This is an island of white-sand beaches and turquoise waters, complemented by a town filled with Caribbean colored clapboard houses and rustic, open-air restaurants. Hotels are clean and comfortable, but if you're looking for lots of action or opulence, you'll be happier in Cancún. A few recent additions provide more luxurious lodging, but they still maintain a decidedly casual atmosphere.
