Where Saint Lucia Sits in the Caribbean
Saint Lucia is one island in a long chain called the Lesser Antilles, which curves from Puerto Rico down to Venezuela. Within that chain, it belongs to a smaller cluster known as the Windward Islands, according to Britannica. Martinique lies about 24 miles north across a strait, and Saint Vincent sits about 21 miles to the south. Barbados is further out to the southeast, across open Atlantic water rather than the calmer Caribbean side.
The island itself is volcanic. Its interior is mountainous, with the twin peaks called the Pitons rising near the town of Soufrière on the west coast. The highest point on the island is Mount Gimie, according to geographic data compiled on Wikipedia’s Saint Lucia geography page.
How to Get There
Saint Lucia has two airports that handle international flights. Hewanorra International Airport sits in the south near Vieux Fort and handles most long-haul international traffic. George F. L. Charles Airport is smaller and closer to Castries in the north, used mainly for flights within the Caribbean region, per Wikipedia’s tourism-in-Saint-Lucia entry.
Capital and Major Towns
Castries is the capital and largest city, built around a natural harbor on the island’s northwest coast. Other notable towns include Gros Islet in the north, known for its beaches and weekly street parties, and Soufrière on the west coast, near the Pitons. Vieux Fort sits at the island’s southern tip.
