Cubagua or Isla de Cubagua (Spanish pronunciation: [ˈisla ðe kuˈβaɣwa]) is the smallest and least populated of the three islands constituting the Venezuelan state of Nueva Esparta, after Isla Margarita and Coche. It is located 16 kilometres (10 mi) north of Araya Peninsula, the closest mainland area.
The island is 9.2 by 3.6 km (5.7 by 2.2 mi) in size, an elliptical shape with the longer axis east-west. Its area is 22.438 km2 (9 sq mi). The coast consists of some beaches as well as cliffs from 5 to 7 metres (16 to 23 ft) high in the south and from 20 to 24 metres (66 to 79 ft) high in the north. The highest elevation of the flat-topped island reaches 32 metres (105 ft).
It is dry and lacks surface water bodies (the only freshwater is found in small underground reservoirs). Annual precipitation is 250 millimetres (10 inches), which is the value of a dry desert. Temperatures are close to 25 °C (77 °F) year-round with little fluctuation.
The desert-like (xerophytic) vegetation of the essentially barren island includes a number of cactus species such as Cardón de Dato (Ritterocereus griseus), Buche, Melón de Cerro, Sabana o Monte (Melocactus caesius), Guamacho (Pereskia guamacho), and Opuntia tuna as well as a few legumes (family Fabaceae) such as Mesquite (Prosopis juliflora), Divi-divi (Caesalpinia coriaria), Poorman’s Friend (Stylosanthes viscosa), and the Sangre Drago (Croton flavens).
The island has small populations of hares, feral goats and a large population of dogs.
The island of Cubagua has no streets or roads. It is served by ferries and other boats from Punta de Piedras, the capital of the municipality of Tubores located 8 km (5 mi) to the northeast on Isla Margarita. The passage takes less than 2 hours. The boat landing pier is located at the eastern end of Playa Charagato, the main settlement of Cubagua.
