Hardangervidda - 4 / 5 day loop around the Hardangerjøkulen glacier
Liseth / Vøringsfoss is the starting point of the tour. You can go either way, I did clockwise. You could also start in Finse...
You head towards Rembesdalseter, then Finse (which is mountain railway stop) and then back via (almost) Kjeldebu.
Only do this in dry conditions. 30% of the trail is swamp / mud, 30% is rock (mossy / slippery when wet) and 40% is normal trail. The part just past Rembesdalseter is going up a plain rock face, not doable when wet. Finse can get quite foggy.
On that note, the markers can be hard to spot, very hard in places.
Lastly, there are a view snow fields / glaciers to cross, crevasses included.
