Sail away to Islas Mujeres. Located just 8 miles off the Yucatan Peninsula, this sleepy island contrasts sharply with the buzz of nearby Cancun. Anchor yourself on Playa del Norte Beach, found a short walk from the ferry station. A crescent of golden sand, its waters are vivid turquoise, shallow and tranquil. Set up camp here to turtle watch, snorkel, kayak and water play. Beachside huts rent umbrellas and other accessories. Hungry? Local cafes excel at affordable lobster.
