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.

This atypical body of water is a volcanic dam lake created by a basaltic lava flow. This is the first of a long series that you will encounter on this GR 30. It is particularly impressive for the many views that we have of the Chaîne des Puys and the Sancy.

Lac Chambon is a lake of volcanic origin. Between its remarkable view of the Monts Dore and its shallow depth (only four meters), swimming becomes very pleasant. As a good walker, you need an hour to hike around the lake. If you prefer water sports, go directly to the leisure base. On the beach, taverns, ice cream parlors and restaurants are also open during the high season.

Chambon Lake owes its origin to a volcanic flow that blocked the Couze Chambon. Beaches are provided on the northern and western parts of the lake, but it is possible to go around them in order to enjoy the calm of nature on the southern banks.
