Los Katíos National Park (Spanish: Parque Nacional de Los Katíos) is a national park located in northwest Colombia which covers 278 square miles (around 720 km sq, or 72,000 hectares). It is a part of the Darién Gap, shared by Panama and Colombia and is contiguous to Darién National Park in Panama. The Pan-American Highway when completed as proposed will pass near or through Los Katíos National Park. 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.
