Cayo Coco (Coco Key) is an island in central Cuba, known for its all-inclusive resorts. It lies within the Ciego de Ávila Province and is part of a chain of islands called Jardines del Rey ("King's Gardens"). The cay is administered by the Morón municipality, has a surface area of 370 km2, and is named after the white ibis, locally called coco (coconut) birds. The island is known for its long beaches and many resort hotels.
The causeway linking Cayo Coco to the mainland is 27 kilometres (17 miles) long and runs across Perros Bay (Bahia de Perros). It took 16 months to build and required 3 million cubic metres (110 million cubic feet) of stone. The causeway caused concern among environmentalists because it disturbed the tidal flow, thus changing the salinity and temperature of the water. A number of gaps were created in the causeway to restore some water flow. Wild flamingos still live in the shallow waters of the bay and can often be seen from the causeway, albeit less frequently. Two short causeways link Cayo Coco to Cayo Guillermo (to the west) and Cayo Romano (to the east).
Still largely wild with swamps and scrubland populated by wild cattle, the islands boast about a dozen large international hotels currently offering approximately 5000 rooms: the Jardines del Rey project plans to eventually offer 32,000 rooms. Beaches are attractive for tourists and the massive coral reef off the north coast attracts divers from around the world.
