Pyhä-Luosto National Park (Pyhä-Luoston kansallispuisto) is a national park in Lapland, Finland. It was created in 2005 by combining Finland's oldest national park, Pyhätunturi National Park (established in 1938), with Luosto. This makes Pyhä-Luosto one of Finland's oldest and newest national parks. The park covers 142 square kilometers (55 square miles). Its most important features include its geological features, old forests, and wetlands.

The foundation of the park is the southernmost 12-peak tunturi line in Finland. These tunturit are the remains of mountains that are 2 billion years old, similar to the Alps. Pine forests that are 200 years old or older grow on the hills. The tallest tunturit are Noitatunturi, 540 meters (1,772 feet), and Ukko-Luosto, 514 meters (1,686 feet).

In 2015, the park had 115,100 visitors, which was fewer than the 128,000 visitors in 2009. However, since 2015, the park has become more popular. In 2023, it was the fifth most visited national park in Finland, and in 2024, it had nearly 199,000 visitors.

Nature

Pyhä-Luosto National Park's landscape includes the southernmost large mountain range in Finland. The park covers a section of twelve major mountain peaks, part of a 35-kilometer-long ridge made of quartzite rock. This ridge is leftover from one of Earth's oldest mountain ranges, which is nearly two billion years old. A famous natural feature in the park is Isokuru Gorge, Finland's deepest gorge, which drops more than 200 meters (660 feet). The gorge reveals clear wave-like patterns in quartzite rocks, showing how glaciers shaped the area during the Ice Age.

The park supports a diverse northern forest ecosystem. The lower slopes and valleys are covered with old-growth forests of pine and spruce, some trees over 400 years old, among the oldest in Finland. These undisturbed forests are home to rare and endangered polypore fungi that depend on dead wood for survival, as well as common northern plants like lingonberry, cloudberry, and crowberry. The forests also provide an important home for woodpeckers, Siberian jays (the park's emblematic bird), and many other species.
