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.

All the treasures of the local heritage: wash houses, bell towers, streams, etc.

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.

Beautiful views of the château, the Grandes Écuries and the Canal Saint-Jean add to the charm of the circuit.
