Worth a visit

- The Signal de St André: The geographer César-François Cassini (1714-1784), who drew up the map of the Kingdom of France in 1744, had a boundary stone erected at the summit for the purpose of his work. It still stands today and has given this place the name "signal".
- Between the points and (12), the route follows the old railway line that linked Messimy to St-Symphorien-sur-Coise from 1914 to 1933.
- The Rontalon botanical trail, approximately 5.5 km long, offers a fun way to discover the local vegetation and wildlife.
- The Paul-Buyer Museum in Rontalon traces the history of agricultural machinery.

A lovely walk in the Monts du Lyonnais,
with impressive panoramic views and the Signal signposts
Most of the elevation gain is in the first section, which is very pleasant

A beautiful hike above the mist that veiled the Alps.
The return journey from Le Signal is a little less pleasant.

We did this hike with our two dogs. It was very cold, but at least it wasn't muddy. It offers some very pretty views from the top, and the descent through the fields is very pleasant.

On a beautiful sunny winter's day, with some sections still muddy, we enjoyed the scenery.
At Le Signal, there were a few hikers and cyclists, but above all, there was a breathtaking view of the Alps emerging from the mist.
The descent wasn't particularly interesting, but overall it was a good hike, completed in 5 hours plus a break.

A beautiful hike in ideal weather, varied, more or less open with beautiful views of Lyon and the Alps, and pleasant passages through the woods. We extended the hike a little by going around Le Châtel towards St André la Côte between 5 and 6.
18.2 km and approximately 600 m of elevation gain.
Thank you for this beautiful route

The distance recorded by our GPS (Garmin) is 17.5 km and the elevation gain is over 650 m
The view from the platform overlooking the Mornant countryside at the top of Le Signal (where there is an orientation table) is remarkable: it opens up widely onto the Pilat Massif, the Monts du Lyonnais and, on the horizon, the entire chain of the Alps from north to south, with Mont Blanc in all its majesty. Of course, it's better when the weather is clear. Nevertheless, depending on the season, the landscape offers an infinite variety of shades: the soft green of spring, the dazzling white of the snow-covered countryside, the cottony white of a sea of clouds from which the Alps rise on the horizon, and in autumn the warm colours of the forest. In a word: pure bliss!
Note the "Land Art Trail" which begins a few steps after climbing the old railway line (points 11 to 12). The forest section gives pride of place to works of art made from natural materials. There are friendly hairy monsters and a fantastic dragon on whose back you can run and throw yourself into its wide-open mouth. A treat for children's imaginations.
But there are also contemporary works whose symbolism always evokes nature and its vital force.
This beautiful hike ends on a high note with a botanical trail, which is unfortunately closed during the winter season but seems well maintained, judging by the small information panels that line it

A beautiful route that was unanimously appreciated by the groups of hikers (up to 25 people) that I have taken there on several occasions.
Of particular note are the artistic and highly original works of art along the "land art" route that follows the old railway line.
Thank you to those who mapped out this route.

Two noteworthy points of interest are the "landArt" route in the Croit Forest and the Rontalon botanical trail. The group I accompanied on this route really enjoyed the hike.

We really enjoyed this hike, with its pretty trails through the woods and few roads. All the elevation gain is up to point 7. Along the old railway line, there are some sculptures made of wood and other materials to admire. There are tables at the St André sign for picnics. No view of the Alps as it was too foggy that day. The botanical trail is very interesting. Worth doing again. Thanks to the author

I usually walk around this area starting from Thurins or Soucieu, which makes the walks considerably longer.

The hike is not difficult, you just need to enjoy climbing. The view from Le Signal is obviously magnificent on a clear day.

My favourite parts are the sections along the botanical trail and through the orchards. Best done in summer or autumn to appreciate the diversity of the landscapes.

The view was a bit obscured by clouds at the St André signal, but it was still superb

A beautiful, fairly sunny autumn hike, with sufficient altitude to rise above the mist and clouds.
