The gorges of Noailles are closed a bypass is in place in 2022 and 2023.
Leaving the village of Mouthier-Haute-Pierre the Via Francigena continues towards Pontarlier along the GR®145. The route usually passes through the “gorges de Noailles” to reach the “source de la Loue”, but since 2022 there have been rockslides and the path has been closed for clearing work and to secure the route. New rockslides have recently occurred and the route will remain closed in 2023 to continue work to make the site safe. A deviation has therefore been put in place from 2022 and will remain in place until further notice. The signposting of the deviation has been put in place by the Doubs departmental hiking committee and you can thus bypass the dangerous area and still reach the “source de la Loue” before resuming your walk towards Pontarlier.
