On the Friday, I did one of the published MTB riding loops, in the Swiss Jura, starting and ending in Saignelégier, not too far from Neuchatel.
Although it was in the hills, it is pretty much up on a plateau, and reasonably easy ride. Mostly on road, track, and farm fields. Total distance was only about 43km, and a GPS track is on my Endomondo log.
