You step off the boat and the Caribbean opens like a bright room — white sand underfoot, turquoise water stretching to the horizon, and the hum of island life at the edges. The day moves in clear stages: sunlit snorkeling in shallow reef gardens, a slow native-boat ride through tangled mangroves, and a nighttime rendezvous with plankton that flare like scattered embers when the sea is disturbed.
