There is a car park on the right bank of the River Bono, near the old suspension footbridge.
(S/E) Take the path that follows the course of the Bono River towards Saint-Avoye. The path initially follows theGR®34for about 3 km, constantly following the Bono River.
(1) At this crossroads, the path continues along the river.
(2) Leave theGR®34here, which heads towards Sainte-Avoye (this will be the route taken for the return journey), and continue along a yellow-markedPR® trail that follows the river upstream.
(3) After crossing the Rohu dyke, at the entrance to the hamlet of En Ty Nuhuy, take the path on the right which continues up the Bono river towards Anse du Téno. You will discover the estuary of the Sal River and, on the other bank, the old Pont Sal tide mill. The path leaves the Sal estuary and followsAnse du Téno along a pretty, slightly steep and shaded path.
(4) Take the path on the right. It crosses a stream and forms a circular loop in the sensitive natural area of the Téno moor. This is a wetland made accessible by the installation of decking.
(5) Make a return trip to the left towards the observatory, about 150 metres away.
(6) Retrace your steps.
(5) Continue to the left. Then leave the Téno circular. Avoid the path on the left, which has become impassable, and continue straight ahead towards the village of Kerchican.
(7) Alternative route: (see practical information).
Turn left onto the Kerchican road. Leave thePR® here and head for the car park 500 m further on, on the left-hand side of the road.
(8) Alternative route: (see practical information).
Enter the car park and you will see thePR® on your right, indicating the direction of the circular Téno.
(9) Turn left onto a wide dirt road. Further on, turn left at the fork and continue for about 200 m to reach the crossroads you passed on the way there.
(4) Turn right and retrace your steps along the Téno cove and the Sal river to reach the crossroads from the outward journey, just after the hamlet of En Ty Nuhuy and the small Rohu dyke.
(2) Take the path on the right that leads to the village of Saint-Avoye and its chapel.
(10) After passing the chapel, take the path that passes in front of a fountain and goes up a sunken lane that leads to a dirt road.
Take this dead-end road on the left for about 700 metres until you reach the end.
(11) A path descends to the left to reach the Bono River.
(1) To return, retrace your steps to get back to the car park (S/E).
