Both Eastern and Western Caribbean itineraries offer great coastlines. The Western Caribbean, though, has more than great beaches: Mexico's Mayan ruins, snorkeling and diving along the coast of Belize, and climbing near natural features like Jamaica's Dunn's River Falls.

The "best" part of the Caribbean to cruise in 2026 depends on your interests: Western, Eastern, or Southern. 1) Western Caribbean (Mexico, Jamaica, Grand Cayman) is best for adventure and history, offering Mayan ruins, cave tubing, and world-class snorkeling. It is often the most affordable route. 2) Eastern Caribbean (St. Thomas, St. Maarten, Puerto Rico) is the "classic" choice, best for shopping and white-sand beaches. These routes often include "Private Island" stops like CocoCay or Labadee. 3) Southern Caribbean (Aruba, Curacao, Grenada) is best for seasoned cruisers and weather-watchers. Because these islands are further south, they are generally outside the "hurricane belt" and offer a more "European-meets-Island" culture with less crowded ports. In 2026, Southern Caribbean cruises often depart from San Juan or Barbados rather than Florida, meaning they require a longer flight but offer a much more exotic and tranquil experience compared to the high-traffic Western and Eastern routes.
