Small pass, but no way to drive into the valley on the D39. Road closed. I didn't even try.

Second pass for today. Pass elevation 1144 m above sea level. Long climb, basically from Saint Germain to here. A total of about 700 m elevation gain and 12 km. The gradient is only 4-6%, but with 20 kg of luggage, everything is difficult ;) Here, too, the weather was still quite cool in very early April. Partly rain, partly windy.
