Sierra Nevada de Santa Marta
The Sierra Nevada de Santa Marta mountain range is located on the Caribbean Sea and is shared with the departments of Magdalena and Cesar. Most of the hydrographic reserves in the Department of La Guajira originate in this mountain range, including the Ranchería River which flows through most of the department from south to north. The Sierra Nevada de Santa Marta was declared by UNESCO as a Biosphere Reserve.
