National Natural Reserve of the High Jura mountain range

At the far south-east of the Jura massif is the long Jura mountain range. From the Rhône water gap to the south, to the Swiss border to the North, and overlooking the Lake Geneva basin, the high Jura mountain range separates the Pays de Gex from the valley of the Valserine.
Created in 1993, the National Natural Reserve ensures the preservation of mountainous environments that could be altered by development and potentially high tourist numbers. The reserve aims to ensure a balance between farming and forest exploitation and preserving the wealth of natural heritage in this area. The diversity of vegetation groups, in various colours and environments, are part of the originality of these high mountain range landscapes.
