Best Island Excursions in Dominican Republic 2026

The Dominican Republic's offshore islands represent the Caribbean at its most idyllic — turquoise water, coconut palm-fringed beaches, vibrant coral reefs, and a sense of genuine tropical escape that even the finest mainland resorts cannot replicate. Island excursions consistently rank among the country's most popular activities, with Saona Island alone welcoming over 500,000 visitors annually.

Saona Island, the largest offshore island within the Cotubanama National Park, has become synonymous with the Dominican Republic vacation experience. The journey there — typically by speedboat outbound and catamaran return — includes a stop at the famous Natural Pool, a sandbar in the middle of the Caribbean Sea where starfish gather in ankle-deep crystal water surrounded by endless blue horizon.

Catalina Island, while less famous than Saona, is prized by snorkeling and diving enthusiasts for its dramatic underwater wall — a sheer coral cliff that drops from shallow reef to 150+ feet in the abyss. The reef here is among the healthiest in the Caribbean, supporting a dazzling array of tropical fish, sea fans, and occasional nurse shark sightings.

For travelers seeking more off-the-beaten-path experiences, Cayo Arena in the remote northwest coast and Cayo Levantado in Samana Bay offer distinctly different island atmospheres. Cayo Arena is a tiny sandbar surrounded by pristine reef with some of the clearest water in the Caribbean, while Cayo Levantado — the famous Bacardi Island — delivers the quintessential Caribbean postcard scene with its white sand beach, swaying palms, and calm turquoise bay waters.
