Cayo Largo del Sur, or simplyCayo Largo ("Long Key”), is a small resort island inCuba, off the south coast of the northwestern part of the main island in theCaribbean Sea. Thecay is about 25 kilometers (16 mi) long and 3 kilometers (1.9 mi) wide and is the second largest island in theCanarreos Archipelago. Cayo Largo is part of the special municipality ofIsla de la Juventud.
Christopher Columbus is said to have visited the island on his second expedition in 1494, and SirFrancis Drake may have also stopped on the island during his circumnavigation of the globe.[citation needed]Pirates also likely used the island as a base.[citation needed] Today, pristinebeach,scuba diving, and wildlife draw tourists to the island, but no people live there permanently; locals who work in the hotels stay for about 20 days, then return to their families on nearby islands. There are five all-inclusive resort hotels on the island. Flights fromArgentina[citation needed],Italy, andCanada serve the island.
Flights fromMiami were halted in December 2019 due to an October U.S. Transportation Department ruling that suspended flights from the U.S. to nine airports in Cuba. The policy stopped air service to all Cuban airports except Havana.[1]
On February 20, 2020, damage to the only airport runway forced tourist passengers return to the mainland via boat.[2]
In November 2024, the island was evacuated prior to the arrival ofHurricane Rafael.

Typically, the fine white sand is packed hard on the surf's edge and allows easy walking.
A major tourist attraction of Cayo Largos are the west beaches, Playa Sirena, and Playo Paraiso. These beaches are a kilometre apart, and one may easily walk between them when the tide is not full. Sirena offers full service facilities for tourists. A shuttle "train" service that used to take tourists from the resorts to these beaches stopped operating for some time but was restarted in 2022.[3] (taxis are still available for this purpose). Paraiso offers one of the finest undeveloped beaches in the world.[citation needed] Activities on the beach may be curtailed during turtle egg laying season. The beach has water sports related to the hotels, a restaurant, dolphin attraction, docks for catamaran trips. The lee side of the beach features tidal flats where many very large starfish congregate and other tropical fish are easily viewed.
Travellers to Cayo Largo should be aware that nudism is tolerated in Cayo Largo and is practiced on the periphery of the resorts in designated areas, and on the many desolate stretches of beaches (20 km) on this island.

Cayo Largo is alimestone island, formed over millions of years from the remains of marine organisms, such as the ones that buildcoral reefs. Living coral reefs form one more attraction for tourists on this island, althoughcoral bleaching has stressed some reef communities in theCaribbean. The northern coast of Cayo Largo consists largely ofmangroves andsalt pans. While the water south of the island appears clear enough to reveal the underlying ocean floor, the water on the north side of the island is cloudy. This cloudy water indicates that sediment is washing off the land surface and into the water or is being stirred up from the shallow sea floor.
In November 2001, the entire island was covered by storm surge inHurricane Michelle.
Vilo Acuña Airport (IATA: CYO;ICAO: MUCL) is an international airport on the island.
A large catamaran style ferry provides surface transportation.
Cayo Largo is also recognized as a noteworthy tourist destination, with its extensive white sand beaches such as Playa Sirena and Playa Paraíso attracting visitors for sunbathing, swimming, snorkeling, and other leisure activities.[4] The island’s clear waters and surrounding coral reefs are popular with scuba divers, and a range of resorts and accommodation options support year-round tourism.
