Trail of the Giants’ Causeway in Thueyts

Unmissable event in Ardèche, the Trail of the Giants’ Causeway is a sports event held every year in the picturesque village of Thueyts, on the first weekend of June, with permanent routes. Curious to know more? We’ll provide more details about these routes, suitable for both hiking and running/trail.

At a running pace

Initiated over 10 years ago, the Trail of the Giants’ Causeway was created by a local association of 9 trail enthusiasts (and Ardèche lovers!). As a friendly sports competition, the trail attracts thousands of participants every year, both beginners and experienced, to test the 3 routes offered during the event. Accessible to all, it offers three routes: La Gravenne (10km), le Ranc Qualiou (20km), and les 3 vallées (51km), which can be done either as a hike or a run (for the most courageous among us). The different routes are permanent, allowing both newcomers and experienced hikers to explore the incredible natural panoramas of the Monts d’Ardèche, the surroundings of the Devil’s Bridge, the Abraham Valley, and the heights of the picturesque village of Jaujac and the banks of the Lignon River.

The Ranc Qualiou route, marked in blue, starting from Rue Pouget in the village of Thueyts as well, takes you on trails of pozzolan (volcanic rock) on the slopes of the Gravenne volcano and towards the cross of Briges and various hamlets. After crossing Combegleyze, les Girauds, la Vernède, and the former hamlet of Fargebelle, these beautiful mountain trails will bring you back to the banks of the Ardèche River and its famous natural site, the Devil’s Bridge.

The 3 Vallées route is the challenge for all endurance adventurers with its 51km (estimated at 10 hours of running for the complete circuit)! It passes through three valleys, hence its name: those of Thueyts, Mayres, and Jaujac. Some more technical passages like the Croix de Chaumienne, Col de Barbejo, or Col d’Abraham will delight elevation enthusiasts above 1200 meters. It’s a true elevator of landscapes that will unfold before you, between the rivers Ardèche, Lignon, and the magnificent volcanic panoramas.
