South of the resorts, down a rutted road and way off the beaten path, lies serene Playa Palancar—a long, walkable beach with hammocks hanging under coconut palms. The on-site dive shop can outfit scuba enthusiasts for trips to the famous Palancar and Columbia reefs, just offshore; boats will take snorkelers out every two hours from 9 to 5. There's also a nice open-air restaurant-bar here if you'd rather just relax. Amenities: food and drink; parking (free); showers; toilets; water sports. Best for: snorkeling; swimming; walking.
