Guanahacabibes Peninsula is the westernmost point on the island of Cuba. It is located in Pinar del Río Province, in the municipality of Sandino and is sparsely populated. The waters surrounding the peninsula are important spiny lobster and red snapper fishing grounds. It also boasts the category of Biosphere Reserve, listed by UNESCO in 1987. Its western extremity, Cape San Antonio, is the westernmost point of Cuba.OverviewIts location in the open waters of the Gulf of Mexico makes it vulnerable to hurricanes. The area was severely affected by Hurricane Ivan in 2004 and Hurricane Wilma in 2005.Guanahacabibes was the site of Cuba's first forced labor camp, started at the end of 1960.ConservationThe Guanahacabibes National Park on the peninsula is one of the country's largest natural reserves and is separated from the rest of the island by white-sand plains where one of Cuba's largest lakeside areas lies. A relatively small area holds some 100 lakes, as well as the largest and purest fields of silica sand, which is 99.8% pure. Nature tourism is a major attraction in the National Park. The area is inhabited by 172 species of birds belonging to 42 families, 11 of which are endemic and 84 are migratory. Experts also believe that 4 of the 7 species of marine turtles living on the planet have survived in the Guanahacabibes Peninsula. The coastline also contains preserved coral reefs, with the northern coast being lined by the cays and isles of the western Colorados Archipelago.
