The best way to get around St. Lucia is by car or minibus, though taxis are also available and water taxis around the island are plentiful. Rental cars can be obtained at the Hewanorra International Airport (UVF) in the southern town of Vieux Fort, which is about 35 miles to the south of Castries.

While having a car offers the most flexibility to explore St. Lucia's spread-out attractions, you do not strictly need one to have a great vacation. Many visitors rely on a combination of taxis and water taxis, especially for traveling between the northern hub of Rodney Bay and the southern sights of Soufrière. Taxis are easily identified by their light blue number plates (TX prefix), though fares should be agreed upon in advance as they are not always metered. For a more "local" experience, the island has an extensive network of minibuses (green M-prefix plates) that are very affordable, though they can be crowded and don't always follow a fixed schedule. Additionally, many high-end resorts offer shuttle services, and adventurous travelers often utilize water taxis to reach secluded beaches like Anse Chastanet or Sugar Beach, which can actually be faster and more scenic than navigating the island's winding, mountainous roads by car.
