Board a small boat, catch the St. Thomas sunset, then slip beneath the surface to watch reefs wake at night. This certified-night dive offers close encounters with lobsters, squid and the eerie calm of nocturnal coral life.
More ways to explore the area's outdoor wonders
You slide off the boat just after dusk, the last light cutting across glassy water while the captain radios one last check. A soft beam from your flashlight parts the dark; coral ridges shift from muted shapes into a fluttering metropolis. Lobsters and squid begin their rounds, and the reef's nocturnal chorus pushes you forward.
