Yes, for Samoens we started with the map from the Tourist office plus the blue IGN map which gives you a better idea of terrain, gradient and whether it’s a path, vehicle track or road. We carried both maps as the waymarking is a bit vague in places. The red, blue and black gradings are as much effort as technical difficulty; some of the most enjoyable trails were marked blue while there is plenty of “black” forest roads.
Over the week we rode most of the stuff accessible from the Joux Plan, Samoens1600 and Morillon access roads below about 1500m (the town is about 700m or so). Generally aimed to climb 500-600m then loose a chunk of height, climb a bit more, loose more height so it was more than one big up and down.
Just flicked through my pics and really, really want to go back. Now.
