Aydat Lake is located at an altitude of 850 meters. It is the largest natural lake in Auvergne. It was born from the lava flow from two wells. Today, it is a place where several nautical activities can be practiced. I highly recommend a quick stop at the terrace of the La Cocotte Bleue restaurant. The view and the welcome are simply perfect!

A creation of the Count of Montlosier, L'Étang de Montlosier is more of a landscape creation. It is artificially created by diversion of the Randanne which then bumps against the lava flow of the Puys de la Vache and Lassolas. The pond covers an area of nearly 1.5 hectares and has no apparent water outlet. This disappears, in fact, in the volcanic strata at the foot of the puys of Lassolas, La Vache, and Mercœur. After a political career spent abroad, François Dominique de Reynaud, Count of Montlosier, tired of political intrigues, retired to his land in Montlosier in 1816. It is a very poor land where agriculture is impossible. The count undertakes to make it possible by transforming the landscape, a work that will take him 22 years. Living with his son in a cottage, he first took care of housing the cattle. The castle will be built later, in 1820. Then, he takes care of clearing, restoring the soil, making hydraulic arrangements and finally cultivating. It goes without saying that the landscape is profoundly modified.
