Description of the walk

Parking near the aqueduct in Champonost.

(S/E) When you leave the car park, under the arches of the aqueduct, follow the road on your left. Turn left at the first crossroads (Rue du Docteur Penard) and follow the arches on your left, which gradually disappear. Continue straight ahead on Rue du Docteur Penard and pass the first roundabout.

(1) When you reach the second roundabout (with a central island), take the second street on your right (Rue Claude Dominget) and continue towards La Chavannerie.

(2) At the crossroads in front of the La Chavannerie clinic, turn right (Rue Favre Garin).

(3) You will come to a crossroads with a stone calvary. Turn left (Avenue Paul Doumer). At No. 41, turn left into Rue René Chapard.

(4) With the Saint-Prix church on your right, head towards the Tourist Office and the media library towards Parc du Boulard. Follow the path along the small Merdansson stream. Go around the pond on the left and continue along the path that runs alongside the stream.

(5) Cross the stream and take the path that climbs up in front of you through the woods. This path leads you to orchards on the plateau of Le Vernay. Ignore the first path on your left, then Rue Jean-Eugène Culet on your left, and continue straight ahead.

(6) At the crossroads, turn left onto Rue François Chanvillard, which will take you back to the old village of Chaponost. Take the first street on the left (Rue Antoine Rouillat). Continue along this street as it turns to the right. At the crossroads, follow Rue Jean-Eugène Culet to the right until it ends. Turn right onto Rue Etienne Radix.

(7) Pass by the former convent of the Antonine Maronite brothers. At the end of the street, turn left, then right onto Rue des Framboisiers. At the end of this street, turn right and return to the car park (S/E).

One of the highlights of the visit was Boulard Park; however, the pond is currently being drained and work is underway there

It is a varied route with plenty of points of interest.
It combines urban and more rural areas.
Well worth exploring.

The approach to the Boulard pond is closed and off-limits to the public. It is therefore not possible to cross the stream; even if you turn back and walk along the other bank of the stream, the last section of the route through the orchards does not exist (which was confirmed to us on site).
For me, the section on roads/tarmac was too long for the hike as a whole.
The first part (name of a street on the right) was difficult to find.
On the other hand, the estimated time and elevation gains were accurate.
We trust Visorando to repeat the experience in the future.

Urban hike mainly on tarmac with narrow pavements and locals who drive a little fast. Worth the detour for the aqueduct and the centre of Chaponost. Pond emptied in October 25

Interesting route with beautiful views

At point 5, the stream crossing is muddy when it rains and the climb through the woods is along a poorly maintained sunken path with very high steps

A pleasant walk, partly urban, allowing you to discover beautiful properties and enjoy a pleasant stroll along the Merdanson stream and pond before climbing up to the plateau at Vernay, where you can admire a beautiful panorama, including the snow-capped Monts du Lyonnais, and end your walk at the magnificent arches of the aqueduct, illuminated by the sun.
Thank you to the author for this new discovery.

Hike starting from the Aqueduct site, then winding through the old village and reaching a natural area
with a stream, a pond, a wooded hill on the plateau and views of the Monts du Lyonnais and the Monts d'Or.
A very educational walk.
Thanks to the author.

This is a walk, not a hike. A loop on a route that is too paved and uninteresting for a "nature" hiker. Takes 1.5 hours, not 2 hours. Best if you live in Chaponost for a family outing on Sunday. Otherwise, don't make the trip to discover the area; there's nothing typical about the houses, even if the aqueduct is worth seeing!

Lots of roads and tarmac. We were able to visit Chaponost and see the beautiful properties. We stopped off at the park, which is very well maintained. An easy walk
