Prise D'Alzeau walks

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

A refreshing walk in the Montagne Noire from the small village of Lacombe (11310) to the Ramondens national forest (Tarn) with a picnic stop near the retaining dyke of the St-Denis basin. Return via the right bank of the Alzeau and passage at the Prise d'Alzeau, source of the Canal du Midi, before climbing back up to Lacombe. Walk checked on 18/06/23. A few details have been added by the author

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.
