First belaystation right, after the first 30m. Then 50 m through the snow to the cave. Then about 40m to the niche on the right side. Then the last 20 m to the end of the route. Abseiling from the tree to the cave. That's about 60 m. And then from there to the first belaystation, unless you have a 70 m ropes, that would propably take you all the way down.
