Select participants and date
The morning ferry slides away from Cruz Bay and the sea opens like a promise. Wind tugs at your hat and the island of St. John rises—a green spine of hills ringed by reef—until the boat slides into the lagoon at Trunk Bay. The water here reads in impossible blues; the sand is the kind that muffles footsteps and forces a slower pace. Guides shepherd visitors toward coral gardens where parrotfish and sergeant majors dart through the breathless clarity.
