Patraflon is a grassy summit in the Friborg Pre-Alps which dominates the Valsainte Valley. It offers a magnificent view of the Swiss Plateau and the Jura. Its wide and regular slopes make it an ideal destination for running, especially in spring and autumn. You can start from the Pré de l'Essert farm and follow the Essert valley, then climb to the summit of Patraflon via a wooded ridge. You can also extend your route by traversing to the nearby summit of Gros Brun, which requires some climbing on the northwest ridge. Enjoy the landscape and tranquility of this little-known region.
