The border continues along Anarjohkas tributary Skiehččanjohka, while the upper part of the river lies within the eponymous Anárjohka national park in Norway.

[2] The river has its sources at Lulit Bissovárri, at an elevation of 549 metres (1,801 ft) in Kautokeino Municipality in Finnmark county, Norway, in the far south of the Finnmarksvidda plateau, in the southwestern parts of Anárjohka National Park.

After Basevuovdi the river turns north, and its largest tributary, the Goššjohka, joins it from the west.

On the Norwegian side, between the border bridge and north to the confluence with Karasjohka, lie the villages of Dorvonjárga and Gámehisnjárga.

Angeli, which lies opposite Basevouvdi on the Norwegian side, is the largest settlement along the river south of Karigasniemi.
