The orientation table that previously existed and the wooden terrace have been removed. The trees have grown, making the view non-existent. Before, on a clear day, it was possible to make out the Eiffel Tower.

Mont Pagnotte is the highest point in Valois and one of the highest in the Paris region, with an altitude of 222 meters. It was also an ancient Celtic and Gallo-Roman colony, of which you can still see some ruins along the way. The trail passes through the magnificent Halatte forest, where you can appreciate the diversity of trees and wildlife. From the summit of Mont Pagnotte, you can admire a panoramic view of the forest and the surrounding countryside. It's the perfect place for a run to escape the city.

Beautiful point of view on the treetops. The panorama is not exceptional but it is the highest point of Valois with 222 m of altitude anyway!

At the top of Mont Pagnotte, not much to see except an antenna. The best is to go down a few tens of meters lower and take advantage of the observatory.
