Turks & Caicos
The turquoise-water islands
Turquoise water and walk-in reefs — with the dive-versus-snorkel line drawn honestly.
Two easy walk-in reefs a short swim off Providenciales, Grace Bay's famous flat turquoise water, and Grand Turk's shallows as a second island. Two honest lines: the best snorkeling is offshore-shallow rather than dense coral, and much of the headline diving here is wall at dive depth.
