Spend the afternoon snorkeling, sipping cocktails and lounging on the beach with a trip to Catalina Island. Set out from Santo Domingo for a coastal drive and 35-minute boat ride to this tropical paradise, known for its palm trees and pure white sands. Once here enjoy a guided snorkeling excursion among colorful coral reefs and marine fishes, then head back to land for a Dominican-style lunch and an open bar. Sample a Cuba Libre, take a swim or soak in the local entertainment. Remember: you're on island time.
