December 23, 2014: It was -2 degrees of Celsius in Grenoble at 9am., but later in higher altitudes (1400m) a mere T-shirt was quite enough when stopping for lunch (with Mont Blanc in the backdrop), even if the temperature did not climb over +10C.

We had a plan to climb to Le Plateau de Sornin, but missed the bus stop in Engins, so we continued to Lans-en-Vercors, and picked the first trailhead to Fôret de Jay.

Note how the “Cédez le passage” sign has been posted. It does not seem a prank, since the sign is fastened well (we checked!)
