Don't do this when it's muddy and when you have luggage! It took us 60 minutes to carry our mountainbikes with 20k luggage up the switch backs...

The Faux d'Enson observation tower is a 9 meter high concrete tower with metal stairs, built in 1989 by the Jura section of the Swiss Alpine Club. It is located at an altitude of 927 meters, at the summit of the Faux d'Enson mountain, which is part of the Mont-Terri range. From the tower, you enjoy a breathtaking view of the whole of Ajoie, as well as the border between France and Switzerland, marked by stone pillars. On a clear day, you can also see the Pays de Montbéliard, the Bernese Alps, the Vosges and the Black Forest. At the top of the tower, an orientation table allows you to identify landmarks on the horizon.
