The Clock Tower and Saint Hugon Chapel

This walk presents no major difficulties apart from the distance. The first part takes place mainly in the woods, the second in the Dauphiné bocage. It will take you past several ponds, up to the Clock Tower, and to the amazing Saint-Hugon Chapel.

Description of the walk

(S/E) Leave the car park heading north-east towards the hill (sign: Châtonnay). Turn left at the church, pass the cemetery and continue to a stop sign. Continue straight ahead. Follow the small road until you pass a memorial to a plane crash on your right, then a pond (Étang Egron) on your left.

(1) Once you have passed the pond, take the first forest path on the right. Very soon, at a fork, take the left-hand branch. Continue heading east, passing several ponds. At the last one, you will come out of the woods.

(2) A little further on, at a crossroads, turn left. You will come to another pond on your right. Once you have passed this pond, before the picnic table on the left, take the path on the right, which is not very visible at first, that runs alongside the pond. At the end of the pond, ignore the path that branches off to the right.

(3) Almost immediately, you will come to a complex crossroads. Ignore the path that climbs diagonally to the left and take the slightly hidden path opposite that continues into the valley. You will see yellow markings. Continue along this path. After crossing the mill stream, it will lead you to the village of Saint-Christophe. At a fork, leave the yellow markings and take the no-entry road opposite (Rue de la Montagne) to reach the D502.

(4) Turn left and then right at the crossroads (towards Châtonnay Centre and Tramolé). Pass the cemetery and then take the first street on the right (towards Tramolé/Culin). At the stop sign, continue straight ahead towards "La Tour du Calvaire". At the fork, turn left (sign: Père Berthier - 475m) and then left again onto the dead-end road (except for pedestrians).

(5) Climb the stairs to the clock tower. Enjoy the view, especially of the Grande Sure. Leave the tower by taking the steep path to the left of the cross. Return to the original path and turn right, following a pebble wall. Be careful not to go past the very steep path on the left, which is made up of wooden steps. This will take you directly to the centre of Châtonnay. When you reach Rue des Tisserands, turn right to join the D502. Turn left and continue for a few dozen metres.

(6) Take the first street on the right, Rue Ferrachet. When it turns right, take the narrow pedestrian passage opposite. When you reach Impasse du Moulin, turn left towards the mill (de la Niverdière). Follow the path that climbs up to the right.

Your path, which climbs quite steeply, leads to a small road. Turn right, then pass a small road on the right that leads to a dog kennel.

(7) You will see the sign for "Nivernière - 520m". Follow the path on the right which descends into a charming little valley and continue to the end. You will pass some ponds on your left. At the third pond, when the road turns to the right, continue straight ahead.

(8) You are at the sign for "Basses Combes - 430m". Take the small road on the left, which climbs steeply. When the slope levels out, you will come to a fork; take the left branch (yellow markings) and you will arrive at a group of houses, the hamlet of Hautes Combes.

(9) Follow the yellow markings to the right (if you are as lucky as I was, you will see rabbits running in all directions...). Follow this small road for a good while, always following the yellow markings.

(10) You will arrive at the sign for "Aquermone Nord - 505m". Turn right towards the Chapelle Saint-Hugon. Your path crosses a farmyard. As you pass, admire the hundred-year-old oak tree of Saint-Hugon. When your small road turns to the right, turn left. You will pass a small pond before reaching the chapel and the spring of Saint-Hugon.

(11) Take the time to read the sign summarising the history of this very modern chapel. Leave the chapel and continue on your way. Pass two paths on your left before reaching a complex crossroads.

(12) At the crossroads of dirt tracks, take the second track on your left (it branches off at about 90°). Quite soon, your path is blocked by a metal barrier. Take the path that branches off to the right. It is narrow and sometimes muddy... It leads to a small road, which you take on the right.

(13) At the sign for "Maison Cazeneuve - 480m", continue straight ahead and pass between two ponds (the one on the right is adorned with a magnificent weeping willow). Continue along this small road, which will take you back to your starting point (S/E).

Notes

The walk starts from the large car park in Lieudieu, along the departmental road. Lieudieu is located in the department of Isère, between La Côte-Saint-André and Saint-Jean-de-Bournay.

There is a water source at the start in Lieudieu, on the way up to the church, and another at the Saint-Hugon Chapel. There are two other water sources in the two cemeteries you pass.

There are no amenities in Lieudieu (the nearest ones are in La Côte-Saint-André or Saint-Jean-de-Bournay). In Châtonnay, there are a few shops, a chemist's and a doctor (according to the municipal website).

The walk can also start in Châtonnay. In this case, park in the Town Hall car park and head west to Rue Ferrachet (marker (6) on the map and in the description).

Worth a visit

The walk takes you past numerous ponds in the undergrowth, but also outside it.
Things to see along the way: the Calvary Tower in Châtonnay, the oak tree and the Chapel of Saint-Hugon, lost in the countryside: http://www.chatonnay-isere.fr/presentati...

A very beautiful and surprising hike with numerous well-maintained ponds; one does not expect to see so many in this region. Indeed, this hike should not be undertaken after heavy rain, as I expected, with many muddy paths; otherwise, it is good training for endurance.

A very pleasant route, which I completed with two friends, allowing us to explore the Bonnevaux forest and all its ponds.
The estimated duration was accurate. There was even a picnic table at the foot of the tower!
It was amazing. It makes you want to come back during the hot weather.

A very beautiful hike, without any difficulties, taking about 3½ hours in the afternoon without a picnic break.
A little muddy in places (it had rained the day before our walk, which took place in bright sunshine on 16 July).

It should be noted that the descent from the clock tower between the points (5) and (6) was not maintained and was full of brambles.

A pleasant walk through ponds and woods. Some paved sections, but with very little traffic.
Part of the route at the beginning is quite muddy due to major forestry work involving heavy machinery.
Beautiful, well-stocked holly bushes.

Partially completed circuit with variations, starting from Châtonnay and looping back to Lieudieu.
The terrain is sometimes muddy, but that's normal in this type of area.
A bit too much tarmac for my liking, but that's hard to avoid if you want to pass through the places described.
All in all, it was a good ride!

The circuit has been extended on its eastern side towards the Chollières ponds to fill the whole day.
Plenty to see, even though the vegetation is still dormant.
A few muddy sections, but that's to be expected in an area with ponds!

We did this hike in the middle of summer, and the wooded sections and proximity to numerous ponds made it very pleasant. Apart from a slightly tarmac start and a few (moderate) climbs, we had a lovely time. It had rained a few days earlier and we encountered a few puddles, but nothing insurmountable. We enjoyed the beautiful view while having a picnic.

Great hike, we actually saw rabbits...
As it had rained the day before, the trail was slippery with large puddles in places... Remember to bring your walking poles!
With my head in the clouds, I missed a turn... but the GPS helped me find my way back!

Thank you for taking the time and effort to leave a comment.

Visorando is aimed at a very wide audience. What may seem trivial to an experienced mountaineer like you may be a challenge for someone who is older, less energetic or less athletic than you. My primary goal is to avoid putting anyone in difficulty.

What strikes me is the reason you gave for rating the route as "moderate". This is how I proceed:
- i identify possible walks on a 1:25,000 IGN map.
- i do the walk, recording the route on my GPS,
- i then compare the two and make any necessary adjustments.
I don't really see how my route can be "average".

You're right, the walk is very good.

Enjoy your walks in the mountains and elsewhere.

Yannick

Being more accustomed to mountain hiking, the description of "steep slope" made us smile. We made two mistakes. Point No. 10 is poorly placed on the route but well described in the commentary.

Very good route, well described and marked. Lots of beautiful undergrowth (best enjoyed during the summer heat) and a few viewpoints. A great time.
