|Roter Fels 2
This is a very cool adventurous route which will keep you on your toes. Just keep to the left following the ample (though at times a bit run out) protection. It's a little grassy at times, but otherwise still a classic route.
While listed as a 6, I would say that it's a little hard for a 5.9, so I gave it a 5.9+ which actually kind of fits with it's relatively sustained difficulty. You of course get some breaks, including a very nice ledge right up at the top.
Head up the climbers trail and go to the far left. This is the farthest route on the left.
