Punta Cana's activities are largely water-based. The coral reef runs close to shore, making snorkelling straightforward from the beach, and scuba diving accessible to beginners. Dolphin Island Park offers swimming with dolphins in open water. For more advanced diving, Isla Catalina and Isla Saona have deeper water, shipwrecks, and underwater caves. On land, ATV tours through Macao Beach territory are popular, and zip-line rides through the forest canopy above Anamuya Lake run through several operators. The Cumayasa River is accessible by boat for rainforest wildlife watching.
