A historic trail used for trade across the border to Sweden, this route was also used by refugees during the German occupation during World War II. The Germans investigated the fell passes, but deemed this one so demanding, they thought any refugees trying to use it would perish, so it was not well watched. Some 3,000 refugees used the route, guided over the fells by local Sámi. The trail was revived as a trekking route, officially opened in 2007. Boat transport to Sørfjorden (+47 75-77-43-29), call well in advance to allow coordination with other travellers. Another route goes to Sweden from Hellmobotn, which is served by ferry from Drag (at least part of the year). The latter is at Norway's narrowest point, 6 km from the fjord to the border. It was deemed easier and bunkers of German watch posts can be seen en route. Both routes are through remote fell areas.
