Live aboard a 40-something-foot yacht, master knot-tying, log dive data, and watch the Milky Way from the deck. Island-hop between St. Lucia, St. Vincent, the Grenadines, and Grenada.
Waterfall-hike through Grand Etang National Park, restore coastal trails, and snorkel coral nurseries off Grenada’s west coast.
Split time between sails and shores—three nights on a catamaran, then rainforest homestays and community projects.
