Pfeilerkopfweg

You shouldn't attempt this route without a 70m rope. Begin to the right of Rattenfänger in the crack and climb to the ledge. Cross the ledge (from belayer's perspective, traverse left across the ledge) and climb over into the crack system of "Gerade R 4" and follow it to the anchor.

Just right of Rattenfänger.

You'll need at least 10 quickdraws plus you have the option of taking some stoppers and slings with you, though it's not necessary.
