“An awesome, continuous 4.5-mile singletrack descent from the Chörbschhornhütte with many turns, berms, and small jumps
— Lost Justpastnowhere
Take some time at the Chörbschhornhütte to enjoy the view because you'll want to focus all your attention on this trail once you take off. Also, check your brakes if you haven't already and lower your seat if you don't have a dropper post.
The next 4.5 miles is an awesome 1000 m (3400 ft) singletrack descent to the valley floor with lots of turns, berms, and small jumps. In the second mile, you'll drop over 300 m (1000 ft) on an average grade of almost 20%. The path is relatively smooth and although narrow, you won't have large stones, roots, or compulsory jumps to contend with.
Most of the ride is above the tree line, so you can see what's coming. In short, you don't have to be a dedicated freerider or downhiller (or have such a bike) to enjoy this descent even if it is quite steep, and you can leave your armor at home which is probably good because the climb up to Chörbschhornhütte is long and arduous.
