Believe it or not, there is a 5.10b route in the cave. It is called Saugeburt (German for Pig’s Birth). You have to climb through a two-metre long, narrow horizontal hole in the middle of the route – hence the name. You can have a long nap while you are lying in the hole, but the crux is getting turned around and escaping back to the steepness! One of my favourites.
