Pyha-Luosto National Park is a national park in Lapland, Finland. It was established in 2005 when Finland's oldest national park, Pyhätunturi National Park (established in 1938) was joined to Luosto. This makes Pyhä-Luosto Finland's oldest but at the same time newest national park. The new park covers 142 square kilometres (55 sq mi). The most important features are geological specialities, old forests and wetlands.
The park's base is formed by Finland's southernmost, 12-peak tunturi line. The tunturis are remnants of Alp-like mountains of 2 billion years of age. 200-year-old or older pine tree forests grow on the hills. The highest tunturis are Noitatunturi, 540 m (1,772 ft), and Ukko-Luosto, 514 m (1,686 ft).
