This is one of the most beautiful sections of the Drac and Isère greenways around Grenoble. In spring, it smells of hay, I love it.

The Col des 4 Seigneurs connects Tavernolles to Gières. From Tavernolles, it is a 7.2 km climb for a 570 m difference in altitude if you go up to the fort. The climb is fairly regular without any major changes in slope. Access to the fort itself is prohibited and dangerous

A wide open ridge, overlooking the city of Grenoble, leading to Mont Jalla. The ridge offers excellent narrow and easy trails, with plenty of options for steeper and technical descents, as well as phenomenal views of the city. These trails are shared, respect hikers and other users, and don't forget to say hello!
