Beautiful views of Freÿr Castle and the river from the Freÿr cliff on the Meuse. A good level of surefootedness is required for the ascent and descent to this vantage point.

Beautiful cliffs on the Meuse River opposite Freÿr Castle. The walk along the narrow paved path along the banks of the Meuse River below the overhanging cliff is quite adventurous. There's a beautiful vantage point on the cliff with a beautiful view of the Meuse and Freÿr Castle.
