Tatra National Park, National park in North Central Slovakia

Tatra National Park covers a mountain region with more than 100 alpine lakes and many waterfalls in the Tatra range. The landscape rises from forested valleys to bare summits above 8500 feet (2600 meters).

Tatra National Park was established on 1 January 1949, making it Slovakia's oldest national park. In 1987 a section of the Western Tatras was added to the protected area. In 1992 it joined the UNESCO Man and the Biosphere Programme together with the adjoining Polish Tatra park, and in 2003 the park and its buffer zone were adjusted. Since 2004 it has belonged to the Natura 2000 network.

The park protects the chamois, which lives on rock faces above the tree line and is often spotted in early summer. Hikers also encounter the marmot, which inhabits alpine meadows and warns of danger with a loud whistle.

The park has 600 km of hiking trails and 16 marked, maintained cycling routes. The administration is based in Svit and Liptovský Mikuláš. The only cave open to the public is Belianska jaskyňa, near the village of Lendak. The most visited tarns are Štrbské pleso and Popradské pleso.

About 300 caves lie within the park, but only the Belianska Cave near the village of Lendak is open to the public. The longest cave system found so far is the Cave of Javorinka, which is not open to visitors.
