GR1 Stage 8: L’Isle-Adam to Viarmes (24 km)

Hello everyone!
GR1: Stage 8 L’Isle-Adam - Viarmes

We will start the hike in L’Isle-Adam, quickly leaving the town to enter the Oise-Pays de France Regional Natural Park. The terrain features a fair amount of elevation gain as we climb through the dense forests of L’Isle-Adam and Carnelle, alternating between shaded woodland trails and open agricultural plateaus. Along the way, we’ll pass local landmarks like the Étang Bleu and the Pierre Turquaise before heading down toward the end of the stage in Viarmes.

!!! If it rains, we will have some muddy parts in the forest (white shoes are still accepted).

The GR1 Project is an opportunity to explore the natural beauty of the Île-de-France region, all within easy reach of Paris. Spanning a total of 550 km, this circular trail takes you around the city in a clockwise direction, offering a unique way to discover the peaceful landscapes, charming forests, and picturesque villages surrounding Paris.
