Castries Harbour in Saint Lucia is a vibrant hub and popular tourist destination. It serves as a port for cruise ships and yachts, offering stunning waterfront views, duty-free shopping, and local craft markets. Exploring the harbor is generally accessible, with relatively flat surfaces, but accessibility may vary in specific areas. Both solo exploration and guided tours are viable options, depending on your preference for independence or structured information. The best time to visit is during the dry season (December to April) to avoid heavy rains. The cost can vary based on activities, from free harbor walks to paid excursions and shopping. A typical visit can range from a couple of hours to a full day, depending on your interests in shopping, dining, and tours.
