Tatamá National Natural Park, National park in western Colombia.

Tatamá National Natural Park is a protected area in western Colombia spanning the Western Cordillera mountain range with high-altitude grasslands and steep terrain. The landscape shifts across different elevations, supporting varied mountain vegetation suited to each altitude zone.

The park was established in 1987 to protect important water sources flowing into the San Juan and Cauca rivers. Its creation was part of a larger effort to safeguard mountain regions in western Colombia.

The park's name comes from Cerro Tatamá, the highest peak in the Western Cordillera within the park. At the summit there is a visitor attention centre where guides can be hired for routes through the park. The area is listed as national natural park no. 36 in Colombia's SINAP protected-area register.

Visitors should hike with certified guides who are familiar with the trails and mountain conditions. Planning ahead for reservations and bringing weather-appropriate gear is essential when visiting due to the elevation changes and unpredictable conditions.

Tatamá's páramo lies above 4,200 m and, with Frontino and El Duende, is one of only three páramos in Colombia that have never been altered by humans. Its steep slopes have kept it one of the least accessible páramos in the world, which is why the park is rated a site of high scientific interest.
