Sierra Nevada de Santa Marta

The Sierra Nevada de Santa Marta is an isolated mountain range separated from the Andes chain that runs through Colombia. Reaching an altitude of 5,700 m (18,700 ft) just 42 km (26 mi) from the Caribbean coast, the Sierra Nevada is the world's highest coastal range. The Sierra Nevada encompasses about 17,000 km2 (6,600 sq mi) and serves as the source of 36 rivers. The range is in the Departments of Magdalena, Cesar and La Guajira.

The highest point of the Sierra Nevada group (and Colombia in general) may be either Pico Cristóbal Colón or Pico Simón Bolívar both in the municipality of Aracataca; it has yet to be determined which is higher. SRTM data and local topographic maps show that their true elevations are approximately 5,700 m (18,700 ft), lower than the 5,775 m (18,947 ft) elevation that is often quoted.

The Sierra Nevada is a compact group, relatively small in area, and completely surrounded by lands with elevations below 200 m (660 ft). The main backbone of the Andes cannot be reached from the Sierra Nevada without dropping below this level. This makes its highest point the world's fifth most prominent summit.

Several peaks in the Sierra Nevada are intervisible with Cerro Paramillo, a 3,730 m (12,240 ft) peak in Antioquia Department. This implies a theoretical direct line of sight of just over 500 km (310 mi), reported to be the longest between any two points on the surface of the Earth.
