This greenway, part of the EuroVelo 3 Scandibérique route (Trondeheim - Paris - Santiago de Compostela), is located in the heart of the rolling landscapes of Lot-et-Garonne, bordering the Gers department, and continues towards the Landes region and the spa town of Barbotan. It is currently being developed on the old railway line between Mezin and Sos and follows the course of the Gélise River. A very pleasant route for friends or family, perfect for enjoying slow tourism while staying in the area's beautiful rural accommodations or as a stopover on a longer journey.
