The highest mountain peaks are in the west where the bedrock is primarily dark Børgefjell granite, which gives the landscape its desolate appearance.

The highest mountain in the park, Kvigtinden, towering 1,699 metres (5,574 ft) above sea level, is found here.

Børgefjell is best known as the home to the rare Arctic fox, although in terms of numbers the wolverine is the most common of the large predators.

Birds of prey are represented by the rough-legged buzzard, which is common in the park, and also the snowy owl and golden eagle.

Sami cultural monuments in the form of settlements and hunting stations can be found both inside the national park and in the border areas around it.

(There might have been some kind of fort here once, possibly to claim tax from the southern Sami people, and also to protect the border from the Swedes.)
