  description: Cane Garden Bay is the Caribbean's hidden gem—a picture-perfect point break that only comes alive a few dozen days per year. When due N swells wrap into this protected bay on Tortola's north shore, long, peeling rights spin down the reef with mechanical precision. The setting is paradise: palm-fringed beach, crystal water, and often just a handful of surfers.
