La Chaux-de-Fonds towards Lake Neuchatel and back

Sweet two hour ride with a spectacular descent down La Tournee, followed by a traverse across the Val de Ruz. The climb from Chezard St Martin is over 10% and on a quiet forested road. From the top of this climb, the route follows the tranquil high mountain valley of the Grand Combe, where you will barely see a soul (the road surface is a bit rough but is tarmac). After the descent to where the mountain tunnel briefly passes pops out of the mountain, there's a 15% climb before rolling back into La Chaux.
