This short hike loops around the warm hills of Séderon, with views over the upper Méouge basin to the Mévouillon fort.

In the past, Séderon was a small trading town, drawing in the surrounding population via the mountain pass where it nestled. Later, the settlement expanded to the south and east, to take advantage of the sunshine. Its altitude of 800m makes it an ideal place to recharge your batteries. The village is crossed by the Méouge river, which rises just upstream. It is dominated by the Rocher de la Tour, a watchtower and relay station in the Middle Ages, of which a few vestiges remain. The orientation table at the top offers a wide view of the surrounding area. The Tower is dotted with thyme. Hyssop can also be found here.
