LE TRAIL DES ARPENTS 2026

Trail enthusiasts are invited to explore the scenic landscapes of Yvelines with the Trail des Arpents 2026, offering runners two distinct routes that cater to both newcomers and seasoned trail runners.
The first option is the shorter but no less captivating Arpent Loop, a 23-kilometer course featuring an elevation gain of 450 meters. This loop starts from Perray-en-Yvelines and takes you through charming villages like Auffargis before venturing into the heart of nature at Bois des 500 Arpents, with its lush forests and serene trails. The route then leads runners to the historic Domaine de l’Abbaye des Vaux-De-Cernay, where ancient walls and tranquil gardens await exploration. Completing this loop brings you back to Perray-en-Yvelines via Auffargis once more.
For those seeking a longer adventure, the Layes Loop offers 42 kilometers of challenging terrain with an elevation gain of 800 meters. Starting from the same point as the Arpent Loop, runners will diverge at Auffargis and continue on to explore lesser-known hamlets such as Les Essarts-Le-Roi. The trail then leads through Dampierre-en-Yvelines before reaching the dramatic cascades of Cernay-la-Ville. This loop showcases a variety of landscapes, from dense forests to picturesque villages, culminating in the serene beauty of the Domaine de l’Abbaye des Vaux-De-Cernay.
Both loops provide an immersive experience through Yvelines' rich history and natural splendor, ensuring that participants are treated to breathtaking scenery at every turn. Whether you're a casual trail runner or someone looking for a more substantial challenge, the Trail des Arpents 2026 offers routes tailored just right for your adventure.
