Description of the walk

Car park at the church in Haut Biol.

(S/E) Leave the church square and take the D51H south (the valley is on your left and the hill is on your right).

Leave a road on your left and take the first right. It climbs towards the hill (signposted "table d'orientation-Le Bois"). Take the first right again between two buildings (ignore the yellow cross). Leave a small path and a small road on your left to join a second road.

(1) Turn left onto Chemin de l'Arête. When you reach the hamlet of L'Arête, the road becomes a dirt track. After the yellow gate to a field, turn right, then ignore another track coming from the left at the corner of a house and continue straight ahead. When you reach a fork, turn left (the right-hand track appears to be a dead end).

(2) When you come out of the woods, during grazing season, you may have to open two gates (it is very important to close them behind you). Your path descends to the right.
When you reach some buildings, immediately take the path on the left. At a stream, continue slightly to the right.

(3) You will arrive at a crossroads with a discreet sign for "Chatinet-559m". Turn left. Leave the path coming from the right and very quickly take a very discreet grassy path that branches off to the left towards the woods. Once in the woods, the path narrows considerably, but this will not last.
When you come out of the woods, you will come to a wide gravel path. Take this path on the left.
At the fork, turn right towards an isolated house. Leave a path that branches off to the right and continue towards the house.

(4) Pass the "Maison Chavrot" and enter the woods again. Follow this wide path. When it meets another path, take the one on the left. Leave another path that comes from your left to reach a clearing.

(5) You will see a sign for "Les Trois Coches - alt. 653m". Take the path on the left towards Biol le Haut (yellow signpost). Leave another path on your left.

(6) At the edge of the woods, at a fork (signposted "Aux Bois - alt. 568m"), take the right-hand path towards Biol Le Haut. You are now on the Montée du Belvédère, which descends (yes, it does!) to the church of Biol le Haut, which you will see very quickly.

(7) Take the time to walk back to the orientation table. It is basic, but will confirm the names of the various peaks. It is unfortunate that a power line has been placed in the foreground...
Back on the path, continue to the right, pass the place called Ribaillère and follow the same route as on the way there until you reach the church car park (S/E).

A beautiful hike with stunning views of the Chartreuse mountains and, of course, the tip of Mont Blanc.

Be careful with the map and the trails you come across, as many of them are not marked on the map (trap).

The tour was completed in slightly overcast and windy conditions, which were not ideal for enjoying the various viewpoints. However, it was still very pleasant and easy. Thank you to the author!

Very pretty hike with magnificent views. Apart from the beginning and end, where you are on a small road in the sun, the rest is very pleasant in the woods and fields.

Done in early May. It started well. But at point 2, I had a big problem with the fence. I was on my own, I weigh barely 50 kg, it took me 10 minutes to put it back in place and I scraped my arm on the barbed wire. I was really tempted to leave without closing it. After that, I was out of breath and in pain everywhere, not in a position to enjoy anything. What a shame!

Pleasant route. At point 5, you can extend the route by approximately 500 metres by continuing straight ahead, passing a few houses and taking the road immediately on the left, which brings you back slightly after point 6, then rejoin the original trail.

A varied route, currently covered in poppies, broom and other flowers, winding its way through fields of crops and pleasant woodland, ideal for hot weather, with farms and livestock.
The exit from the woods is easy, with just one barrier that is easy to close.
Despite the cloudy sky, you can see the Alps in the distance, with an orientation table indicating the names of the peaks and the surrounding area.
Thanks to the author for this peaceful and well-maintained country walk.
