COLOMBIA, SOUTH AMERICA--- ..The Parque Nacional Natural de Sierra Nevada del Cocuy, Chita y Güicán (commonly called the Parque Nacional Natural El Cocuy) in Colombia, is a 306,000 hectare (about 1181 square miles) park in Northwestern Colombia. Up until a few years ago, much of the park area was controlled by Colombian guerillas, but is now mostly safe and has become an increasingly popular destination for local and foreign tourists. The park includes 21 peaks over 16, 400 feet with the highest peak, Ritacuba Blanco, at 17483 feet. ..Town of El Cocuy. ..Photos by Dennis Drenner for the New York Times. ..Assignment ID: 30077786A.
