The river Waldnaab has shaped the massive granite rocks between Falkenberg and Windischeschenbach.
It runs between rocky slopes and in its bed there are huge boulders, some with basins and holes.
Uncanny rock formations, 30 to 50 metres high, and sleek rocks are to be found along the river.
Green ferns, diverse flowers, birch and beech trees and the waves and white horses of the water make the valley a picturesque and mystical place.
