Quiet climbing area close to public transit. There's a wide range of climbing from 3 to 9 with varying styles from slab to crack climbing. Limestone is pretty solid but seems quite polished on some easier routes. Wall height is 10-20 meters on the smaller walls, and up to 48 meters on the main wall, providing opportunities for several multipitch climbs.
By car from central Warstein, travel south on B55. Turn left on Am Hillenberg, parking lot is on the left immediately after crossing the river.
By bus 650 or R76, get off at Fliegenpark.
Approach starts from the driveway to the parking lot. Enter the forest and walk along a path until you will find the climbing walls visible from the path. It is a 5 minute walk to the main wall.
