If your idea of relaxation is lazing in a hammock watching butterflies drift by, you will adore Las Ranitas. Originally designed by a French couple to be their heavenly Mexican estate, this serene ecological boutique hotel sits on a fabulous coral sand beach at the entrance of Sian Ka'an Reserve on the Riviera Maya. Sea-facing bedrooms and suites are reached along quiet paths through the gardens. At Bow Window restaurant, Mexican cuisine is paired with tantalizing daily French specials.
