Fodor's Expert Review Fatima Bay

Although the marina is the main focus here, Puerto Aventuras's beaches are naturally stunning and seldom crowded. The main one, Fatima Bay, commonly referred to as Omni Beach, stretches nearly 3 km (2 miles) south between Chac Hal Al condominiums and the Grand Peninsula residence. Its shallow, calm waters are kid-friendly, especially inside the breakwater. Farther out the temperature drops, making for a refreshing swim. To the north is a smaller bay, known as Chan Yu Yum, used by guests of the Catalonia Resort; better beaches lie just south of Puerto Aventuras in the community of Xpu-Há. Amenities: food and drink. Best for: snorkeling; swimming.
