Nice descent, but very steep in places with partly loose and uneven ground.
The descent starts at the refuge, but you shouldn't follow the path I chose there, because that's not one ;-)
The descent of the trail from the Arnsberghütte down to the Kolonnenweg is borderline. Maybe attractive for downhill bikers, but very difficult to master from a technical point of view. The descent is about 200 m long and leads very steeply downhill. The trail leads over loose stones and smooth ground. I can only recommend that every normal MTB rider avoids or bypasses this trail.
