In the Pont Granval reserve, a small stone bridge crosses a quiet river and offers a picturesque passage. This technical path, with climbs and descents around the river, winds through the heart of unspoiled nature. The rustic and charming stone bridge adds character to your mountain bike ride. The trails around the bridge offer varied challenges with rocky passages and shaded areas.
