A large number of seven-day cruises to the Southern Caribbean leave from San Juan, Puerto Rico, in order to reach the largest number of islands in the shortest period of time.
Ports of call often include:

The Antigua cruise dock
Unique attractions include Shirley Heights with its military fortifications and overlook of English Harbour; the historical Sea View Farm Village with displays of folk pottery available for purchase; Harmony Hall Art Gallery, the showplace of island art; and Museum of Antigua and Barbuda, which displays the islands' historical past.
Unique attractions include the Flower Forest that combines a botanical garden and nature trail; Andromeda Natural Gardens, with six acres of tropical plants and flowers; and Harrison's Cave, which includes underground streams and a 40-foot waterfall.
Dominica is promoting itself as an ecotourism vacation and with good reason. It is one of the better hiking experiences in the Caribbean because of rain forests, mountains and waterfalls.
St. Kitts & Nevis (Nee-vis) promotes itself as an ecotourism destination because it is quiet and undeveloped compared to many other islands. Unique attractions include climbing a dormant volcano, numerous hikes, bird watching and the usual assortment of water sports.
Unique attractions include Pigeon Island National Landmark with a history of Amerindians, piracy and battles between the English and French; Fond d'Or Nature Historic Park with more island history, nature and culture; and Fond Doux Estate, an authentic working plantation. The views in the more remote part of the island are among the best in the Caribbean.
This small but beautiful island has relatively few unique attractions, although visitors are more likely to go because of cruises and for quiet stopover vacations. Attractions include Bay of Grand Case, which has the best restaurants on the island; sailing to nearby St. Barths and Anguilla; and the panoramic views of Fort Louis.
Any list of attractions starts with shopping in the capitol city of Charlotte Amalie on St. Thomas. Buck Island is one of the few fully protected marine parks in the United States..Virgin Islands National Park includes an underwater reserve that makes up 5,650 acres. For these reasons, U.S. Virgin Islands abounds with snorkeling and diving opportunities.
