Saint-Martin-du-Tertre (Val-d'Oise) walks

The Carnelle National Forest is a forest located on a hill 25 km north of Paris. Its summit (altitude 210 m) is one of the highest points in the Val d'Oise. The variety of its landscapes makes it one of the most pleasant sites in the region. This hike follows part of the northern flank of the forest, allowing you to discover some interesting features of the forest and its surroundings.

La randonnée se déroule d'abord à travers la Forêt de Carnelle, avec un passage à la superbe Allée couverte de la Pierre Turquaise, la plus imposante d'Ile-de-France. On continue en forêt puis à travers champs, pas loin de l'Oise, pour une visite à l'ancienne Abbaye de Royaumont. On termine entre bois, prés, champs et zones résidentielles.

The hike starts at Royaumont Abbey and takes you through a mainly rural area, dominated by forests and farms, with numerous horse breeding establishments.

From Nerville-la-Forêt, take a short hike in the Forêt de l'Isles Adam with visits to three villages and three churches. This hike is popular in summer when it is hot thanks to the cool shade of the trees in this forest, and also in winter as the ground is not too muddy.

A very varied walk north-east of Luzarches: peaceful valleys, beautiful trees in the Forest of Coye and the remains of the former Abbey of Hérivaux, where B. Constant lived (after largely destroying it...) The walk mainly follows marked paths (PR® at the start, thenGR®1andGR® 655). Very peaceful despite the proximity of Paris.
