In reply to Chris Mock:
I was there at the end of august last year, was pretty warm in the sun, but loads of shady bouldering in the forest areas, some of the crags get shade, or you can work your way around through the day to stay in the shade.
There is free camping up near Ewige Jagdgrunde, if your looking to keep the out goings down, but its not that big an area, and its first come first served.
Food was pretty cheep, depending where you went
