Freyr Rocks along the Meuse

Highlight • Climb

One of the largest climbing areas in Belgium with over 600 routes, some with high levels of difficulty. Also very nice for hiking between the rocks - watch out for falling rocks when climbing at the top!

The view is still the most beautiful from the top of the rock heads. You should be a bit free from giddiness and sure-footed here.

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.

The Montaigle rock formations include: • A limestone massif on which the medieval ruins lie. • Prehistoric caves that bear witness to thousands of years of human occupation. • Historically significant finds that have contributed to our understanding of the Aurignacian culture. • Unique cliffs and boulders with unusual shapes, which are currently protected and where climbing is prohibited.
