The GTJ runs through the Jura Mountains from Mandeure (Doubs) to Culoz (Ain), crossing the Haut-Jura Regional Nature Park and offering a detour into Switzerland. The route suggested here covers the second half of the itinerary. Opened in 2004, the GTJ follows the GR®5, GR®9 and GR® de Pays trails for 400 km. Winding along ridges, skirting lakes and emerging from forests, this is a route accessible to most people, with no particular difficulty. It can be tackled as a 2–3-day trip for families, or as the full 15–20-day route. The route winds through the heart of the Haut-Jura Regional Nature Park and the Haute Chaîne du Jura National Nature Reserve: a protected area to be explored with respect.

Open from 1 April to 30 November – subject to snow conditions. The section from the Chalet d’Arvière to Pont de La Loi is the sixth stage of the six-day walking tour “La GTJ from Mijoux”. The GR®9 enters the Ain department via Mijoux, before following the spectacular ridges of the Monts-Jura, passing through the Crêt de la Neige, the highest point of the massif. It then descends towards Bellegarde-sur-Valserine, crosses the Retord plateau and then crosses the Grand Colombier. The trail continues its route to Culoz and the Rhône Valley, before leaving the Ain to reach Savoie and continuing southwards.
