Bornes Massif

The massif is bounded on the east by the Thônes depression and the Aravis Range, where the highest peaks of the Northern Prealps are to be found, to the south-west by Lake Annecy and the Bauges Massif, and to the north by the valley of Arve and Chablais.

As with all the prealpine massifs, the Aravis chain is primarily formed of limestone and its derivatives.

The stations are first and foremost mountain villages where there remains significant farming activity.

Reblochon was first made in Le Grand-Bornand, and is now produced in large quantities using traditional methods in the massif's valleys.

Two important markets are held weekly at Thônes and at Le Grand-Bornand.
