Take a half-day excursion to Trunk Bay in St. John, known as the "Emerald of the Caribbean." As one of the most stunning beaches in the Caribbean, Trunk Bay offers the perfect setting to swim, snorkel and relax. Start your tour on a narrated ferry ride to St. John. Upon arriving in the charming town of Cruz Bay, you'll board an open-air safari bus for a scenic drive to Trunk Bay. Bring your camera, as you'll make three photo stops along the way. Bordered by sea grape trees, coconut palms, and tropical forests, the crystalline blue-green waters of Trunk Bay are teeming with coral reef life. After a short orientation, you'll set out on the famous underwater snorkel trail for over an hour, following markers that describe the many species of fish and corals that make Trunk Bay their home. Return to port via the ferry.
