Hangest-sur-Somme loop

After boarding at the Breilloire lock, go up the canalized Somme and enjoy the descent in one of the most natural spots of the valley... Board upstream of the lock on the right bank and go upstream on the Somme against the current. Disembark on the left bank (on your right), then carry your boat for a few meters to embark downstream of the right bank dam on the old Somme. Take a break in the heart of the Cavins marsh, a natural environment of great ecological and landscape interest. At the confluence, turn right and go upstream to the lock. If you want to continue your route to Long, turn left and refer to the nautical route between Flixecourt and Long. Disembark on the right bank (on your left) downstream of the lock.
