Public Transport Timetable

A low-altitude bisse, you can enjoy it’s trail throughout the year. The trail is easy and suitable for push-chairs. If you wish, rather than retracing your steps back to your starting point, it is possible to find your way back along the Lozentse river (although this option is not possible with a push-chair). Take care not to miss the fork in the path taking you back to Grugnay and your starting point!
