And it's precisely this waterfall that makes Biberstein Castle such a special place. A wonderful view of the waterfall from the road below the castle. A very beautiful transition from the stream to the waterfall. This impressive scene is best viewed from the lower road.

It's an impressive spot to stand below the castle and observe the small waterfall. It's beautifully integrated into the castle's architectural masterpiece. The small village stream cascades a few meters here. A lovely path around and below completes the idyllic overall picture.

This route is a very nice steady climb on very good asphalted smooth surface with a climb always between 6-10 % with the last part right before the summit creasing to 15 % but only for the length of 100 meters.
