Most of the problems back here are shaded pretty much all day. You will be crawling around through tunnels and passages to get between problems. Several classics and hard testpieces exist back here in the nether regions of the Maze, such as the Funk problems V6-V10, the Egg V9, Glas Roof V9, Flower Power V10/11, Nagual V13 and Couer de Leon V13. Because of the shade this is a great place to climb when it is warm out and it is sheltered from the wind, though pulling down in the warm temps can be difficult. Because you have to be on a tour when back here and because of the tight confines, at times it can feel crowded but all you have to do is slip around a corner and there is nobody there, just don't stray.
Take a tour to the Maze and from the meadow between the Maze and the main spur looking east. Find the German photo route boulder, unmistakable, it looks like a klingon warship, and head in under it to the left side.
