Rougeanne (rivière) walks

This is an easy hike, sheltered from the sun for 90% of the route. The hike can be done in either direction. You will be better sheltered from the sun if you follow the directions given here.

A lovely little walk from the Bassin de Saint-Denis to the Prise Alzeau and back along the stream.

360 years ago, Pierre Paul Riquet had the trial trench for the Canal du Midi dug. The official purpose of this small diversion canal was to prove that large quantities of water could be brought from the Montagne Noire to the Naurouze threshold, where the planned navigation canal would have its "dividing point", its highest watercourse. However, for Riquet, the stakes were much higher: he also wanted to prove that he was fully capable of managing a project as large as the gigantic structure he had planned. To convince Colbert and the commission responsible for examining the feasibility of the project, he offered to finance the test canal himself and only be reimbursed if the objectives were achieved... Theoutcome proved this stubborn man right! This walk takes you on a journey of discovery to find traces of this "Rigole d'Essai" in the Alzeau valley, starting from the village of Lacombe. Parking is available opposite the town hall.
