Unique attractions include Bay of Grand Case, sailing ventures to nearby St. Barths and Anguilla, and the panoramic views of historic Fort Louis.

The Caribbean's most famous attractions offer a chance for vacationers to embrace nature, go adventuring and experience wildlife up close.
People who take western Caribbean cruises will have the chance to try two activities popular on Central American stops -- canopying and cave tubing.
Canopying is common in countries such as Honduras and Costa Rica. Visitors climb a ladder up a tree as high as 100 feet into the air. They are strapped to zip lines and glide from one tree to another with views of rain forests, monkeys and mountains.
Cave tubing in Belize is the most popular adventure excursion in the country. Visitors go to Sibun Caves Branch Archaeological Park, where they jump into a grotto, sink into a large inner tube, and float down a river and through a series of dark caves once used by Mayans for religious ceremonies.
A half dozen destinations including Cancun and the Bahamas offer visitors a chance to swim with trained dolphins in large enclosed pens.
Another swimming adventure is in Barbados, which is one of the few locations with excursions to swim with giant sea turtles that have become comfortable having people in the water with them.
Various snorkeling trips at places like the U.S. Virgin Islands might provide a chance at spotting barracudas.
At Stingray City off Grand Cayman, vacationers can take excursion boats out to a sandbar where a large school of sting ray have become used to swimming with people and even touching them. Visitors jump into the water, which is only three or four feet deep, and go snorkeling with the sting rays.
The most famous waterfalls in the Caribbean is located on Jamaica at Dunn's River Falls. Visitors climb the waterfalls in a daisy chain of people. The climb up the rocks and through the splashing water is 600 feet and challenging, but it draws all ages and anyone who is moderately fit.
Other islands have numerous and sometimes more challenging hikes through rain forests before reaching waterfalls. Islands with well-known falls include St. Lucia, Trinidad, Dominica and Grenada.
Anyone with an interest in history will find Old San Juan, Puerto Rico, as a starting point for understanding the history of the Caribbean. Sites include the forts of San Cristobal and El Morro, both built in the 1500s; and La Fortaleza, also built in the 1500s and the oldest governor's mansion in the Western Hemisphere still in use.
Many other Caribbean destinations such as the British Virgin Islands still have forts, buildings and churches dating back centuries to the time of the original Spanish, Dutch and British explorers.
