Parking is available next to the town hall in Bolozon, or there is a large car park for hikers (in case of high traffic) a little further down, which is signposted.
(S/E) From the town hall, go down the road that leads to the river. At the second hairpin bend, leave the road to go up the other side and immediately take the path on the right.
(1) Leave this path 100 m further on and climb up into the field on the left, following a more or less visible track. A little further up, you will find a path.
(2) Follow the path which continues along the hillside and a little higher up in hairpin bends to Balvay.
(3) Just after the fence, take the gently sloping path on the right to reach Mont Balvay, which offers a beautiful view of the Ain Gorges.
(4) Take the same path back to the hamlet of Balvay.
(3) Cross it and then turn left to climb the opposite slope via a path that leads to Solomiat. Pass the Sainte-Marie-Madeleine Chapel and the cemetery to reach the centre of the hamlet.
(5) Turn left onto a wide path that crosses the Champ Baudin meadows.
(6) Shortly before reaching the forest, leave this path and follow a track on the right through the field, which leads to the path towards the village of Vers. Signposts mark the route. The climb through the woods is well marked, and the path is narrow but pleasant.
When you leave the woods, turn right into a large, steeply sloping field to reach the village of Vers. At the top of the field, when you reach the farm track, you can take a look to the right at the viewpoint. However, it lacks a bit of perspective.
To reach Vers, turn left at the top of the field. Further on, veer left to go around a poorly maintained farm and reach the main street.
(7) Turn left, then keep left at the three-way junction and follow the road, which turns into a farm track. Walk a long way across fields before reaching a wooded area. This route offers a view of the landscape around the Ain Gorges.
(8) Leave the farm track and turn left onto a path that leads through the woods to Napt. This slightly downhill path is narrow but well marked.
(9) Pass the picnic tables on the right and then a little further on at the crossroads on the left. Cross the village, passing in front of the church. A little further on, at the war memorial, turn left down the hill towards Bolozon. Negotiate a left-hand bend and start a long straight stretch.
(10) Before the power lines, leave the road and follow a path on the right that shortens the route by avoiding a bend. Once you return to the road at a bend, climb a few metres to find the path again on the right. Pass under the railway line and join a tarmac road at a bend.
(11) Continue straight ahead into the Ravin de la Serra.
(12) At the fork just before Bolozon, take the path on the right to cross the charming village and return to the car park at the town hall (S/E).
