A warm Atlantic breeze lifts the salt from the harbor as visitors step off an air‑conditioned shuttle and into a compact world of Bermudian nature. The day begins at the Bermuda Aquarium, where aviary calls and the clack of peacock feet meet tanks full of reef life; then the route slips inland to a stone stairway that leads down, 203.41 feet below the island surface, to caverns lit by still pools that catch the light like small, ancient mirrors.
