Resse loop

Located at the French-Swiss border, at 1815 meters above sea level, the Col de Vernaz (pronounced "Verne") connects the Valley of Chevenne (perpendicular to the Abondance Valley) and the Au de Taney, above the lake of the same name.lt is one of the possible crossing points for the ascent of the Cornettes de Bise.

This pass located entirely in France near the Vernaz pass allows connections between several valleys.In the North-East, a path climbs slightly then crosses level to the north until the Vernaz pass. In the south, a path comes from the chalets of Resse, which can be reached by two routes coming from the bottom of the valley and joining the clearing of Plan de Resse. On the east side, a more or less level path comes from the nearby Serpentin pass, located at the top of the Arvouin valley, above the lake and homonymous chalets.

The Cornettes de Bise massif is located between the Abondance valley and the Tanay valley, in Switzerland. Located in the town of La Chapelle d'Abondance, it peaks at 2432 m above sea level and is part of the Natura 2000 network.Chamois, mouflons, golden eagles and notably the Alpine ibex, whose (border) population is estimated at around 700 individuals, can be seen on this massif. Certain species, such as the blue thistle, are also abundant on the site, but are nevertheless rare in France or in Europe. The angular relief of the Cornettes de Bise is composed of hard limestone rocks. The slopes are steep, even abrupt, with numerous rocky bars and scree. By decree of 2 August 2013, the Cornettes de Bise is a classified site because of its picturesque character. A classified site is a remarkable natural area whose historical, artistic, scientific, legendary or picturesque character requires, in the name of the general interest, that it be preserved in its current state and that it be protected from any serious damage (destruction, alteration, trivialisation, etc.). Natura 2000 is a network of protected natural sites throughout Europe, identified for the rarity or fragility of their wild species and the natural habitats that shelter them. The aim is to preserve the biodiversity of these areas in the long term without banning all human activities and to enhance the natural heritage of the area. Natura 2000 is not a nature reserve in the strict sense.
