Restaurant Cenote Azul
Perched on the rim of the 300-foot-deep cenote, this palapa restaurant charges a MX$50 entrance fee to access the site. Busloads of tourists come to dine on chicken, pork, and fish dishes, as well as house specialties like the seafood platter and shrimp kebab. Although the setting surpasses food, it's still worth lingering over a meal to gaze out over the deep blue waters. After your food digests, enjoy a swim off the dock. There's also a souvenir shop.
