There is a lending library near by, and you can find a Camino De Santiago stamp hidden in a niche. You also have two or three fountains to get fresh water.

Starting from Morez, the climb is steep in parts but easier than the slog from Nyon. The scenery? Stunning all the way, especially crossing from France into Switzerland at La Cure. In March, the top (1232m) was deep in snow and freezing, so be prepared. Then it’s all downhill.. literally, through Saint-Cergue and into a twisty, brake-testing descent to Nyon, where it was warm enough for a T-shirt. One ride, two countries, skipping through seasons.
