Starting from La Robine sur Galabre, we go up the gorges by road before turning off at Ainac on a gravel track. This track has some passages at almost 20% which will probably require a good development or pushing the bike a little. The track then allows you to reach the Col de Fontbelle by a nice, smooth descent. This climb is beautiful but physically demanding.

From Sisteron, the Col de Fontbelle is 26.3 kilometers of climbs with segments at 6 or 7%, and others between 1.5 and 5%. In your ascent, passing the intermediate Mézien pass after the 6th kilometer tells you that you have made the first part complicated and that you are starting the second part, long but less steep. On the open parts of the pass, you can see the mountain of Gueruen and the mountain of Mélan and its Grande Aiguille.

The Col de Fontbelle culminates at 1304m. From the village of Thoard it is a climb of almost 13km which comes in two parts. The first is the most difficult with sustained percentages over almost 9 km including 3 at more than 8% on average which will take you to the hamlet of Mélan then the intermediate pass of Hyssop (1236m) where moreover an exceptional panorama will offer to you (we don't make an effort for nothing anyway). The second part is relatively simple with lower percentages, barely 2.5 km at 3% average which joins the col de Fontbelle located in the forest in a VERY isolated way
