Start your half-day coastal cruise when you meet up with your guide and tour group in Port Castries, where you'll board your boat and cruise out of the harbor. Sip soft drinks and water to stay cool; locally made rum punch will be available after snorkeling.
En route to Soufrière, check out the towering Pitons, recognized by UNESCO as a World Heritage Site. Go ashore to visit Sulphur Springs, the world's only drive-in volcano. You'll also visit two impressive waterfalls, Toraille and Diamond Falls in the Diamond Botanical Gardens.
Back on the boat, set off for Anse Chastanet and Marigot Bay, both of which provide swimming and snorkeling opportunities. Don the provided snorkel gear and dive in, searching for brown and black coral, as well as parrotfish and other tropical creatures. In Marigot Bay, explore the areas where the classic film Dr. Dolittle was filmed.
The boat will drop you off at your original departure point in Port Castries.
