Los Katíos National Natural Park (Spanish: Parque Nacional Natural (PNN) Los Katíos) is a protected area located in northwest Colombia which covers about 720 km2 (280 sq mi). The elevation ranges between 50 and 600 m (160 and 1,970 ft). It is a part of the Darién Gap, a densely forested area shared by Panama and Colombia, and is contiguous with the Darién National Park in Panama. The Pan-American Highway, when completed as proposed, would pass near or through Los Katíos. The park was declared a World Heritage Site in 1994 due to the extraordinary diversity of plant and animal species represented. The park contains over 25% of the bird species reported for Colombia in an area less than 1% of the total Colombian territory.
The topography of the Los Katios National Park is diverse, with low hills, forests and wet plains comprising its total area.The two largest parts of the park are the Serranía del Darién mountains, which lie to the west, and the Atrato River floodplains in the east. The floodplains hold exceptionally fertile soil and consist of alluvial plains of two types. One consists of low-lying terraces that flood often and the other has high terraces that seldom flood. There are also low hills of up to 250 metres (820 ft) in elevation and others that are 600 metres (2,000 ft) high. Swampy marshes spread for nearly half of the park's total area. The wetlands of the Atrato floodplain are unique. Cativo, one of the indigenous species, can grow to a height of 50 metres (160 ft). It lends its name to a formation called 'catival', something that is found nowhere in the world except Colombia, south Central America and Jamaica.
