The GTJ crosses the entire Haut-Jura Regional Nature Park, with a foray into neighbouring Switzerland. Inaugurated in 2004, the GTJ on foot follows the Grande Randonnée GR® 5 and GR® 9 trails, as well as the GR® de Pays. With the Grande Traversée du Jura on foot, lovers of nature and wide-open spaces will experience intense moments in a gentle mountain environment. Undulating over ridges, spanning cluses, emerging from a forest to skirt a lake, this is a gentle itinerary with no particular difficulties, taking in the most beautiful paths in the Jura Mountains. Accessible to all, it offers a total of 400 km of trails and a multitude of different landscapes and atmospheres. To meet every hiker's needs, the trail can be adapted to suit every taste: from 2 to 3-day hikes well-suited to families, to walks for hikers in search of rejuvenation, to more physically demanding hikes, and why not ... the complete route, to be completed in 15 or 20 days.
Balisage : The marking of the GTJ on foot complies with the national marking charter drawn up by the Fédération Française de Randonnée. As such, the GTJ benefits from the GR® designation - sentier de grande randonnée - with its famous white and red markings.Directional signposts are gradually being installed at the main crossroads. They can bear both the GR® marking and the GTJ pedestrian visual.The maintenance and marking of long-distance footpaths is the responsibility of the Comités Départementaux de Randonnée Pédestre. The latter sign agreements with hiking associations or, in some cases, with the trail maintenance departments of communes, communities of communes or tourist offices.
