This Highlight is in a protected area
Please check local regulations for: Parc naturel régional du Vexin Français
Location: Haute-Isle, Pontoise, Ile-de-France, France
Please note, in order to protect endangered wildlife, access to the chalk peaks in the commune of Haute-Isle is prohibited every year from March 1 to June 30 by prefectural decree. The paths to mass in Chantemesle are therefore cut off.
Furthermore, following a collapse the previous summer, the Piton du Colombier is prohibited at all times for obvious safety reasons.
