The Camel

Highlight • Summit

One of the still visible elements of the Roman aqueduct of Gier, where nature and time have played with the stones to give them this improbable shape reminiscent of a camel (or more surely a dromedary!).

This siphon bridge is part of the Roman Aqueduct of Gier, one of the four aqueducts built to supply Lyon with water. Located on the banks of the Garon, this piece of heritage blends perfectly into the bucolic setting.

March 7, 2025, [Rando] Le chameau 🐫🐫

The natural area of the Vallée en Barret is a remarkable area. Having not reached Chameau a few weeks ago because of a bridge washed away on the Furon, we decided to return by another path, in this case the path of the Gallic rooster 🐓from Brignais .... which turns out to be a fairly busy road .... we are reaching the limits of collaborative map backgrounds !!! Only IGN mentions "route" of the Gallic Rooster and not "path" 🐔 .... After an original start and views of the town of Brignais, there are 3KM not very glamorous ... Once left this roadside ... It's all good! And it's definitely a camel, there's only one hump on the profile of the hike.😄.... Enjoy ...or not, maybe wait until the bridge is redone or until the water level allows the crossing by jumping from one stone to another
