Kayak the Lucayan Caves & Gold Rock Beach with the island's 20-year ecotour outfit
This is the one true off-the-ship adventure at this port: you paddle quiet mangrove creeks into Lucayan National Park, climb down into the limestone caves that cap one of the planet's longest underwater cave systems, then land on Gold Rock Beach -- the cinematic, near-empty white-sand flat where 'Pirates of the Caribbean' was filmed. A naturalist guide leads the whole day, and door-to-door van transport, lunch and gear are all in the price. Budget ~6 hours door-to-door, so it eats most of your port day -- the trade for the natural-wonder memory most first-timers would regret skipping.
