The Jura High Route is 299km long, stretching from Dielsdorf, outside Zurich, to Borex, a small village to the north of Geneva. Along the way, it passes over the highest summits of the Swiss Jura. It traverses meadowland and forest and visits isolated farms, secluded villages locked in a world all their own, historic small towns, ruined castles. There are stretches of riverside walking and belvedere paths that trace the very crest of the ridge with huge views to embrace an ever-varied panorama. Here in the Jura it is possible to take a walk in the sky undisturbed by the crowds. "The Jura and its High Route" offer an unhurried sense of calm, a pedestrian adventure in a world of green. The purpose of the Winter Ski Traverses section is twofold. First to point out the vast possibilities for enjoyable winter walking on skis in the Jura; and second to persuade those walkers and backpackers who have not yet taken to skis that they are missing an unforgettable experience. The author has attempted to give enough information to set you in the right direction and to assess whether you think you will enjoy the nature of the skiing. Much is left to individual initiative. There is no point giving day-by-day descriptions as times, and even routes, will vary enormously with conditions and whether you are backpacking or staying in gites d'etapes.
