The smallest of the three main U.S. Virgin Islands, St. John was an early pioneer in Caribbean eco-tourism. More than half of its 20 square miles are undeveloped — and will stay that way — as they constitute Virgin Islands National Park, created in 1956 from holdings donated by U.S. philanthropist and conservationist Laurance Rockefeller. Much of St. John’s glorious white-sand beaches, coastline and surrounding seas are also protected, either through the park or the Virgin Islands Coral Reef National Monument.

Dramatic geology, unspoiled landscapes, quiet coves and gorgeous beaches are all part of Virgin Gorda’s appeal. Along the western ridge of the plump middle is Gorda Peak National Park, whose trails deliver stunning panoramic views. At the island’s southernmost tip is its most famous landmark, the Baths. Here massive granite boulders form tidal pools, grottoes and arches, and separate the white sands of Devil’s Bay and Spring Bay beaches. Spanish Town and Virgin Gorda Yacht Harbour are laid-back centers of commercial and maritime activity.

The capital town of Basseterre is the bustling gateway to the beautiful beaches and lush rainforest of St. Kitts. The island was among the first in the Caribbean to be colonized by the French and English, a complex legacy found in and around Basseterre Circus at such sights as the Anglican and Catholic churches, the Berkeley Memorial, and National Museum. A drive along the coast leads to the landmark Brimstone Hill Fortress and National Park, an imposing military structure built from volcanic rock by African slaves. St.

Antigua boasts an intricate coastline of bays, coves, and inlets, and a plethora of white-sand beaches. Set inside one of the island’s great natural harbors, St. John’s is the bustling capital, maritime hub and center for commerce, including a lively farmers’ and crafts market. The British left a lasting imprint on the city, from Fort James and Fort Barrington guarding the harbor entrance to the gleaming white towers of the landmark St. John’s Cathedral. Inside the 18th-century Court House, the Museum of Antigua and Barbuda showcases local history dating to the first Arawak settlements.
