By train: From Biel/BIenne, change at Delémont and take the S3 towards Porrentruy, exit at St-Ursanne. From Basel the S3 runs directly to St-Ursanne. Once there, follow the small brown Eco-Chalet signs, take the road towards the Viaduct (railway bridge), go down the small path on your right next to the bridge to the cantonal road, cross the pedestrian crossing to the intersection and turn left. The Eco-Chalet is located at the end of Chemin du Bel'Oiseau.
By car: exit around the A16 St-Ursanne motorway. At the first roundabout take the third exit then in front of the chapel turn left on Chemin du Bel'Oiseau street, pass in front of the football field, under the Viaduct and continue until the end and there you are: it’s the last house.
