Catalina Island, also known as Isla Catalina, is a tropical gem in the Caribbean Sea, located 2.4 kilometers from the mainland in the Dominican Republic. It is a small but diverse island with ecosystems ranging from sand dunes to mangroves and reefs. The island is known for its pristine beaches, vibrant coral reefs, and rich marine life, making it a popular destination for snorkeling and diving. The island's highest point is only 18 meters above sea level, and it is part of a nature reserve, meaning visitors cannot stay overnight. Instead, they can enjoy boat tours that offer snorkeling and sightseeing opportunities. Catalina Island is also famous for the shipwreck of Captain Kidd's 1699 ship Quedagh Merchant, which was discovered in 2007 and is now a significant historical site. The island's natural beauty and recreational activities make it a must-visit destination for those seeking a tranquil Caribbean escape. GoDominicanRepublic.com
