Stretching approximately 800 m, the bisse (one of the region's historic irrigation channels) of Ossona is an important tourist attraction. Strolls along the waterside are very popular and allow tourists to regenerate themselves in a peaceful and relaxing setting. The bisse is also used to irrigate the area, using either spray or flowing irrigation. The bisse was restored respecting its age-old course and construction.
At the entrance to the villages of St-Martin and Suen, follow the signs for Ossona. After approximately 2 km you will reach the Muzet carpark where you can leave your car.
