The boulder is located on the left part of the stable. A nice start with a large train in the "crack". There, long shimmy to the trowels and then out to grab the ledge ahead. The legs push into the crack and pry out thus ... tada, up to the under-grip scale, done.
From the south on the A7, Nordheim-Nord and the B3 in the direction of Alfeld. Drive just before Alfeld left to Gerzen and up the slope. In the second Entrance to the dirt road, walk up the dirt road a piece, then you see the stable right slope.
