This is the bolted line on the east wall inside the Troll Hut. Start from a sloping ledge and clip a low first bolt, make a move to the jug and continue up the arete to the right to chain anchors with a locking carabiner. DON'T STEAL THE CARABINER, unless you are a total schmuck-munching copraphagic tool.
From the Troll Wall, follow the trail down to the ledge and through the squeeze between boulders to drop down the hill until you can see the hallway inside the Hut. Continue down the trail to the point where it bends around to enter this hallway. Carefully make your way down into the hall, and the route starts from the far end on the left. Lower or rap from anchors, but DON'T TOPROPE DIRECTLY THROUGH THE ANCHORS, please!
Four bolts, two top anchors with chains.
