Catalina Island is a small uninhabited island off the coast of La Romana, known for its pristine white beaches and crystal-clear turquoise waters perfect for snorkeling and diving. The island is protected and features coral reefs teeming with marine life including tropical fish, rays, and sea turtles. Day trips from Bayahibe or La Romana typically include boat transfer, beach time, lunch, and snorkeling equipment. The famous 'Wall' dive site drops from shallow waters to deep reef, suitable for both beginners and experienced divers.
