Vadvetjåkka National Park, National park in Kiruna Municipality, Sweden

Vadvetjåkka is a national park in northern Sweden featuring mountainous terrain with a network of cave systems. The landscape includes alpine plants and sits close to the border with Norway.

Vadvetjåkka was made a national park in 1920, Sweden's northernmost, to keep a high-nordic mountain landscape in its natural state. It lies in Talma sameby, Kiruna municipality, Lapland, northwest of Torneträsk on the Norwegian border, and covers 2,630 hectares of birch forest, glacier, mire, water and bare fell.

Sámi communities have deep roots here, practicing reindeer herding across these northern lands as part of their way of life. Visitors walking through the landscape can sense how people have adapted to this remote terrain.

The park has no road access and lacks developed visitor facilities. Anyone planning to explore here needs to bring their own supplies and suitable equipment.

The limestone bands along the ridge hold some of Sweden's largest karst caves, including one 155 metres deep. The bedrock is mainly easily weathered limestone, and the park has no marked trails or cabins.
