The route follows the trail of "Norge på tvers" (Norway across, https://www.norgepatvers.no/), a trail marked by The Norwegian Trekking Association (DNT) which starts at the Swedish border at Sylsjøen and ends near the ocean at Stjørdal. The trail passes six cabins owned by DNT, and is a popular seven-day hiking trip during summer.
