# Bornes massif

The Bornes massif (French: Massif des Bornes) are a mountainous massif in the north French Prealps in the department of Haute-Savoie. It has 20 peaks higher than 2000 m and is a popular destination for winter sports. The Massif is the source of the celebrated cheese Reblochon.

## Geography
### Location

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. The name "Aravis Massif" is also used to refer to the whole massif, possibly an effect of tourist marketing.
The massif can be accessed though numerous open valleys which separate the massif's peaks:
* From Annecy via the Bluffy col (631 m) or via the recently widened Dingy-Saint-Clair pass, both of which lead to Thônes,
* From Bonneville via the Borne gorge which leads to Saint-Jean-de-Sixt,
* From the east (Megève) via the Aravis col (1486 m, with a view of Mont Blanc) which leads to La Clusaz,
* From Cluses to the north-east via the col de la Colombière, closed in winter, which leads to Le Grand-Bornand,
* From the south (Faverges, Ugine) via the Marais col (843 m) which leads to Thônes.
Two important rivers traverse the massif:
* The Fier from Mont Charvin in the Aravis at Annecy passing by Thônes, the crossroads of the valleys,
* The Borne de la Pointe-Percée at Bonneville which flows into the Arve, passing by le Grand-Bornand and le Petit-Bornand.

As well as its peaks, it has plateaus which are slightly elevated but difficult to access, such as the plateau des Glières tragically famous from the time of the Second World War.

## Geology

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

## Activities
### Tourist station

The massif benefits from exceptional snow considering its moderate altitude. It hosts two stations for the winter sports Alpine skiing and cross-country skiing, with pistes from 900m up to 2000m:
* Le Grand-Bornand (Chinaillon)
* Le Mont-Saxonnex (pronounced "saxxonay")
* Saint-Jean-de-Sixt
Tourist activities are also very popular in summer. The stations are first and foremost mountain villages where there remains significant farming activity.
The Glières Plateau is likewise a well-known site for cross-country skiing.

### Economy

The massif is the source of reblochon, the famous cheese. 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. There is also a notable wood industry.
