Celebrity Constellation: 7-Night Southern Caribbean

San Juan cruise port is one of the busiest in the Caribbean and one of the few that doubles as both a major embarkation point and a popular port of call. The port sits in Old San Juan, the historic colonial core of Puerto Rico's capital, founded by Spanish colonists in 1521.

St. Thomas cruise port is one of the busiest stops on Eastern Caribbean itineraries and the hub of the US Virgin Islands cruise scene. The port handles two main cruise terminals.

Basseterre cruise port in St. Kitts uses the Port Zante terminal, a purpose-built cruise facility in the heart of Basseterre, the capital of St. Kitts and Nevis. Port Zante includes two dedicated cruise piers capable of berthing the largest modern ships plus a marina, restaurants, shops, and the Amina Craft Market.

St. Lucia is one of the Caribbean's most topographically dramatic islands, defined by the twin volcanic peaks of the Pitons rising sharply from the southwestern coast. The Castries cruise port sits on the island's northwest side, with ships docking at either Pointe Seraphine (a duty-free shopping complex within walking distance of downtown Castries) or the La Place Carenage terminal on the opposite side of the harbor.

Barbados cruise port is in Bridgetown, the capital of the easternmost Caribbean island. Bridgetown Port (Deep Water Harbour) sits just outside the city's UNESCO-listed historic center, with modern terminal facilities including 21 duty-free shops, restaurants, car rental agencies, and a tourism office.
