Circular in the Étangs de Mepieu Regional Nature Reserve

A lovely, relatively easy walk along roads and paths, offering the chance to discover the flora, fauna and habitats of this regional nature reserve. No major difficulties apart from a steep climb halfway along the route.

A review dated 17/04/23 indicates that a section from (6) onwards is now private, but it is possible that the signposted path has been diverted or that the walker could not find the way due to roadworks. Please could anyone passing through this area confirm whether this is the case or not.

Description of the walk

Message from a hiker ==> Since 17/04/23, the path is closed beyond (6) (the path on the left) and (7): a quarry has just been opened by VICAT, so there are lorries, diggers, etc. There is therefore a barrier with ‘No Entry’ signs!

Park in the car park by the oven and washhouse in the hamlet of Faverges.

(Start/Finish) Walk up the street heading south-east. At the end of Rue de Penelon, you’ll reach a T-junction with two tarmac roads; turn left and walk for about a hundred metres alongside the houses. At the last house, near the waste collection point, you’ll reach the junction where the road meets the track.

(1) Turn left and follow the lovely, carriageable track under the canopy of trees, continuing straight on towards Chogne. Pass close to the D14a, cross a road and reach another junction near a tiny pond.

(2) Set off straight ahead onto the path marked with a Yellow Rectangle, leaving the pond on your right. At the Y-junction about 200 metres on, turn right onto the tarmac road. Pass houses below on your right whilst staying on the road, and head about 200 metres into a woodland.

(3) As you emerge from the woodland, less than 100 metres on, turn left onto the ViaRhona (shared cycle path). At the next junction between the ViaRhona and a path joining from the left, stay on the ViaRhona and turn right until you reach the junction with a local road.

(4) Turn left to stay on the ViaRhona, which is now shared with motor vehicles (very little traffic). You’ll reach another junction.

(5) Continue to the right – this is still the ViaRhona – and stay on the tarmac road. At the T-junction between two tarmac roads, turn right, staying on the ViaRhona throughout, and you’ll reach an industrial site (with an overhead crane from the nearby quarry); pass under the overhead crane.

(6) After the overhead crane, take the path straight ahead that climbs uphill, leaving the quarry on your left, until you reach the end of the fence. At the junction at the corner of the fence, turn 90° to the left (leaving the wire fence on your left) and continue uphill. Stay on the path to reach the Étang de Barral.

(7) Here, there is an option: you can take a path on the left to go to the Étang de la Fulye, then retrace your steps. Return to the path on the left; you will soon reach the junction with the tarmac road; turn left here to enter Mépieu.

(8) Turn left onto the D16, carry on straight ahead, follow the Grand Étang, and arrive beneath the high-voltage power line.

(9) Follow the nature trail to the junction with the Route de Faverges, near a fountain and a bread oven.

(10) Turn right and, after about 300 metres, you’ll reach the starting point (S/E).

Notes

Make sure you wear a good pair of shoes, even low-cut ones, for the stony paths. There is a fountain at the start and finish, and benches along the route.
A drinking fountain in Mepieu: turn right at (8) and walk for about a hundred metres. No unpaved sections; the route is accessible all year round. Don’t forget your camera and a good pair of binoculars.
Easily accessible with a dog, though keep it on a lead as there is still some traffic on the roads used.

Worth a visit

Faverges, Mépieu and Chogne are hamlets straight out of an interior design magazine. The stone houses and ovens are characteristic of northern Isère (Balcons du Dauphiné) in eastern Bugey. The agricultural landscapes are typical, with their hedgerows.
The ponds in the regional nature reserve offer the chance to spot wildlife (great egrets, grey and purple herons, red-crested pochards, red-billed ducks, great crested grebes, roe deer…) and remarkable flora, particularly in spring and autumn.
Stag beetles fly in droves in the early summer evenings. Special mention must be made of the Étang de Baral, which is magnificent in its lush green setting.

Hi,
There is quite a bit of information missing, given that there are several wash houses and bread ovens in Faverges.
There is not enough information when it says right or left; a little more detail is needed, given that the yellow markings are very random. It's a shame.

For this hike, we recommend parking at the FAVERGES town hall car park (more spaces available)
Easy hike with many paved areas (cycle and footpaths)
At point 6, the path is blocked due to the extension of the quarry, but a detour has been set up
This path has been rebuilt (bulldozer passage) with a sign at each end

A pleasant hike in good weather. It's true that much of the route is paved, but that wasn't a problem. I can confirm that after checkpoint 6, Vicat built a bypass road. Not knowing where it led, we went around the hill (through the woods, where paths had been cleared) and found our way back to the original route. Thank you

We went hiking on a grey day, but without rain... We parked at the Faverges village hall car park, which was a good decision as there were about ten of us and there wouldn't have been enough space at the planned starting point for the hike.
There was practically no climbing, and a detour was planned around the clearing, adding an extra 45 minutes to the hike. We had lunch in the forest on logs. It was perfect. On the way back, we stopped at the medieval festival in Creys Mépieu, which was perfect. Thank you!

hike to do with the IGN map. No markings, so we got lost several times, which was a shame.

In fact, I had already done a route of the Creys Mépieu reserve with a friend who had a guidebook (same name as the hike).
This route is north of the one I did (the only common points are from 6 to 8).
It was an uninteresting walk because there were a lot of roads and very few water sources.
starting from Mépieu (point 8), then heading towards (point 6), follow the southern edge of the Praille pond and then the Serre pond to the D1075 (Lancin side).
Go up the Serre pond on the other side (Mépieu side) to the Serre pond observation point, then return to Mépieu.
This route (south) has very few roads and more contact with the ponds.
Note: at point 6 of the route, the path is blocked due to the expansion of the quarry (a detour is planned).

WARNING! As of today (17/04/23), the path is closed after numbers 6 (path on the left) and 7: VICAT has just opened a quarry, so there are lorries, diggers, etc. There is a barrier with signs! You may be able to pass through on Sundays at your own risk...

A beautiful hike on this sunny early March day. The paved paths are not busy. Indeed, beautiful colours!
A wonderful discovery of the Mépieu ponds with some large birds.
We decided to briefly leave the trail before point 7 to reach the large pond via a small, well-marked path around the site marked 'Potet' on the map. At this time of year, there is a lovely view when you arrive at the pond and lots of flowers in the undergrowth.
Thank you for this pleasant walk.

Departure with a view of the Bugey Mountains, crossing vast expanses of untouched or ploughed fields, meeting the ViaRhona, numerous ponds that are quiet at this time of year, and a wooded area where primroses and violets are beginning to appear.
Beautiful stone houses, ovens and typical fountains in the hamlets.
Thanks to the author for this discovery

The route is fairly well signposted, but 80% of it is tarmac. Apart from the ponds at the end of the route, it is not particularly interesting.
