Cayo Largo del Sur is a beach paradise in its purest form: a small coral island in the Canarreos archipelago, south of Cuba, famous for some of the most beautiful beaches in the country and the Caribbean. Here there are no towns or local life beyond tourism: the cay is, essentially, an enclave of nature, dazzling white sand, turquoise waters and all-inclusive resorts, designed for completely disconnecting and devoting yourself to sun, sea and rest.
Its beaches are legendary: the long Playa Sirena, considered by many the best on the cay, with its fine sand and its calm sea; Playa Paraíso, with shallow, transparent waters; and long stretches of pristine coast where sea turtles nest. The waters, of extraordinary clarity, make Cayo Largo a first-rate destination for diving and snorkeling, with reefs, marine life and excellent visibility. You can also visit nearby islets teeming with iguanas and birds.
This guide covers the essentials of Cayo Largo del Sur with a practical eye: its must-see beaches, the sea activities (diving, snorkeling, catamaran rides), the wildlife —turtles, iguanas, birds—, the all-inclusive scheme and how to reach this isolated cay, accessible mainly by plane. It's a destination for those seeking a postcard beach, tranquility and marine nature, far from the bustle of the cities.
📖 History of Cayo Largo del Sur
Cayo Largo del Sur forms part of the Canarreos archipelago, south of Cuba, an area of coral cays with a history tied to navigation, fishing and, in other times, the passage of corsairs and pirates through the Caribbean. For centuries it was a practically uninhabited place, a refuge for wildlife and for sea turtles that come to lay their eggs on its beaches. Unlike most Cuban destinations, Cayo Largo has no urban or colonial past: its development is entirely touristic and recent, the result of Cuba's bet on sun-and-beach tourism in the last decades of the 20th century, which transformed it into an exclusive resort enclave while keeping its natural setting. The full history is on our history page.

1
Playa Sirena and Playa Paraíso
Two of the best beaches in Cuba: dazzling white sand and a turquoise, calm sea.
The beaches are the reason for Cayo Largo's existence, and two stand out above the rest. Playa Sirena, at the western tip of the cay, is often considered the best beach in Cuba: a wide, very long stretch of fine white sand, with calm, shallow waters of a dazzling turquoise, ideal for swimming and spending the day. It usually has services (umbrellas, a restaurant, gear rental) and is reached by transfers from the hotels.
Next to it, Playa Paraíso lives up to its name: shallow, transparent, serene waters that look like a natural pool, perfect for relaxing. Both beaches, adjoining in the west of the cay, form a spectacular ensemble and are the great 'must-do' excursion of the island. It's best to set out early to enjoy them more calmly and to bring sun protection, water and everything you need for the day.
ℹ️ Distance: Western tip of the cay; access with a transfer (boat or vehicle) from the resorts · Best time to go: Dry season (November to April); early for more calm · Entry: Beaches free; boat transfer to Playa Sirena approx. US$ 10–20 round trip; lounger US$ 3–5 (2025; check) · Duration: Full day at the beach
2
Diving and snorkeling on the reefs
Crystal-clear waters and coral reefs that make Cayo Largo a first-rate diving destination.
Cayo Largo del Sur is one of Cuba's great diving destinations. Its waters, of exceptional clarity and visibility, and its nearby coral reefs are home to rich marine life: corals, sponges, colorful fish, moray eels, lobsters, turtles, rays and, at some points, encounters with larger fauna. There are dives for all levels, from intro dives for beginners to spots for experienced divers, with walls, caves and sunken ships.
Snorkeling is also magnificent, accessible on boat outings to reefs and nearby islets. The cay's dive centers organize the activities and gear rental. The combination of warm waters, transparency and biodiversity makes the underwater world one of the island's great attractions. It's best to respect the corals and wildlife, use reef-friendly sunscreen and always follow the guides.
ℹ️ Distance: Reefs off the cay; outings from the marina's dive centers · Best time to go: Dry season, with better visibility and a calm sea · Entry: Two-tank dive approx. US$ 50–70; intro dive US$ 70–90; Open Water course US$ 350–450 (2025; check) · Duration: Half a day to a full day
3
Cayo Iguana and the wildlife islets
A classic excursion to Cayo Iguana, populated by iguanas, and to other islets of birds and pelicans.
A classic Cayo Largo excursion is the visit to nearby islets, especially Cayo Iguana (Cayo Iguanas), populated by numerous iguanas that approach visitors in an almost prehistoric setting. The trip usually continues to other cays teeming with pelicans, gulls and various seabirds, and to sandbanks in the middle of the sea where the water barely reaches your waist.
The catamaran or launch rides combine sailing over turquoise waters, swimming at sandbanks, one or several snorkeling stops over reefs and the visit to these islets, often with a seafood lunch on board or on a cay. It's one of the most memorable days of the stay. It's best not to feed or disturb the wildlife, keep your distance and follow the guides' instructions.
ℹ️ Distance: Islets near the cay; reached by catamaran or launch from the marina · Best time to go: Dry season, with a calm sea · Entry: Catamaran excursion to the islets approx. US$ 60–95 per person, usually includes snorkeling and lunch (2025; check) · Duration: Full day
4
Turtle farm and the nesting beaches
The cay's sea turtle hatchery and the pristine beaches where these threatened species nest.
The pristine beaches of Cayo Largo are nesting areas for sea turtles, and the cay has a turtle farm or center (hatchery) where you can see specimens of different species and learn about the protection and breeding work for these threatened animals. It's a short, accessible and educational visit, especially appreciated by families.
During the nesting season (which varies by species, generally between spring and summer), with luck and respect you can witness part of the turtles' cycle: the arrival of the females to lay eggs or the hatching of the young. The cay takes part in conservation programs, since these beaches are among the most important for turtles in Cuba. It's best to visit the farm with a guide and always respect the wildlife protection rules.
ℹ️ Distance: Turtle farm on the cay; nesting beaches along the coast · Best time to go: Nesting season (spring-summer depending on species) to see the cycle · Entry: Visit to the turtle farm approx. US$ 3–8 per person (2025; check) · Duration: 1 to 2 hours
5
Sport fishing and water sports
Deep-sea and fly-fishing in rich waters, plus water sports from the cay's marina.
The waters surrounding Cayo Largo, rich and little-exploited, are a good setting for sport fishing: deep-sea fishing (marlin, mahi-mahi, tuna) in the deep waters of the south, and fly-fishing for bonefish, permit and tarpon in the shallows and mangroves of the Canarreos, in catch-and-release mode. The cay's marina organizes outings with guides and boats.
Beyond fishing, the resorts and the marina offer water sports: kayak, paddle, sailing catamaran, windsurfing and, in some cases, jet-ski, many included in the all-inclusive plan. It's an active way to enjoy the cay's turquoise sea. It's best to book the fishing outings in advance and check the season for each species.
ℹ️ Distance: Outings from the cay's marina · Best time to go: Dry season; season depending on the fishing species · Entry: Deep-sea fishing outing approx. US$ 300–500 per boat (half day); non-motorized water sports usually included at the resort (2025; check) · Duration: Half a day to a full day
6
The service village and sunset on the cay
The cay's small service hub (marina and airport) and the sunsets over the Caribbean.
Although Cayo Largo has no towns or urban life, it does have a small service hub around the marina and Vilo Acuña airport: bars, a shop or two, the excursion pier and the base of the water-sports centers. It's the logistical heart of the cay, from where the boat rides to the western beaches and the islets depart, and a pleasant spot to have a drink by the sea.
One of the great pleasures of the cay, free and within everyone's reach, are its sunsets: the sun falls over the Caribbean horizon in a spectacle of colors that closes each beach day. Walking along the shore at dusk, with the warm sand and the glowing sky, is one of those simple experiences that sum up Cayo Largo's charm. It's best to book the excursions from the marina a day in advance.
ℹ️ Distance: Marina and airport area; shore just steps from the resorts · Best time to go: Sunset; any time of year · Entry: Strolling and watching the sunset is free; drinks at the bars separate · Duration: 1 to 2 hours
