Tips from the Community

Fred Urrutia
October 15, 2025, Forêt d'Ermenonville

Spanning over 3,300 hectares, the Ermenonville forest, along with those of Halatte and Chantilly, forms the vast Trois Forêts massif. Once owned by the monks of Chaalis and other nearby abbeys, it is now renowned for its moors, Scots pines, and sandy soil, home to rare wildlife such as the European nightjar and the praying mantis.

Pine trees, sand, ferns galore. In short, you're transported elsewhere and breathe in the air of the Landes...
