Los Roques Archipelago

Los Roques, Venezuela — a 300-island national park of uninhabited coral cays and lagoons in the Caribbean, with sand as fine and water as clear as anywhere in the region.

Fly into the single settlement of Gran Roque, then hire a boat to reach uninhabited cays like Cayo de Agua or Francisqui for the day — there's no infrastructure beyond the main island, so bring cash and sun protection. Kitesurfing conditions on the eastern cays are considered some of the best in the Caribbean.
