Cayo Largo del Sur is a coral island located in the Canarreos Archipelago, south of Cuba's main landmass. Covering an area of approximately 37.5 square kilometers, the island is renowned for its pristine white sand beaches and crystal-clear turquoise waters. Situated in the Caribbean Sea, it provides exceptional opportunities for diving and snorkeling due to the extensive coral reef systems nearby. The island has no permanent resident population; almost all inhabitants are workers employed by the local hotels on a seasonal basis. Cayo Largo serves as a crucial nesting ground for several species of sea turtles, including the Green Sea Turtle and the Hawksbill Turtle. A local turtle sanctuary is dedicated to the conservation of these marine reptiles, allowing visitors to participate in educational programs. Despite its popularity as a tourist destination, much of the island remains undeveloped and is protected as a natural reserve.

Getting there
The island lacks a land connection to the mainland; access is almost exclusively by domestic flights arriving at its small international airport, or occasionally via private boat charters.

Parking
Motorized transport is minimal on the island itself; visitors mostly rely on walking, rented bicycles, golf carts, or shuttle services provided directly by the resort hotels.
Safety
The tourist zones are heavily secured and extremely safe. However, always respect the fragile coral reef ecosystems by maintaining buoyancy and never touching the marine structures.
