I see it too, in Strava. I checked komoot too, and ut.no. I see that most trails, and most "heat" in Strava is on the 548250327 path via Knutvikveien. But to double confirm this, I will go up there myself in August and check out the conditions. I will get back to you when I have checked out the area. It might be a "signage" issue as well, at the fork where Vannverksbakken and Knutvikveien splits into two (68.24722292050312, 14.55179197146163). Stay tuned :)
