The GR-91 is a classic among hiking enthusiasts. This Grande Randonnée (GR) crosses the beautiful Vercors National Park which, lucky for us, is not far from home. The trek is split into two sections. After some research, we chose to do the section from Corrençon-en-Vercors to Châtillon-en-Diois which would take us through the Hauts Plateaux Nature Reserve where we’d traverse high plateaus, forests, and Alpine pastures, and have stunning views of the Massif du Vercors mountain range.

This trek had been on our “list of things to do” for awhile so we finally picked the dates and… did it! We planned for a three-day trek but after Mathieu spent the night on a deflated air mattress on top of rocky ground, we decided to cut the trip short.

Both days of hiking were wonderful but the second day from Jasse du Play to Châtillon-en-Diois was our favorite. This was where we finally had stunning views of Le Grand Veymont, the highest mountain in the Massif du Vercors (2341 m; 7680 ft) and saw the unmistakable mesa top of Mont Aiguille (2,087 m; 6,847 ft). And after climbing up onto the high plateau, we had amazing views of the snow-capped Alps in the distance. It was breathtaking! (Check out the video below.)

While it’s possible to do this trek in two days, I’d recommend doing it in three. If it weren’t for that darn faulty air mattress, we would have spent the second night sleeping under a nearly-full moon on the high plateau looking out over the mountains of the Vercors and the Alps (next time!).

If you’re in the area, add this trek to your “list.” You won’t be disappointed. But don’t take my word for it… see for yourself!

Enjoy!

Useful Info

• WATER: At the time we did this trek (July 2-3, 2023), the springs along the trail were flowing so we had no problem getting water. But I’ve read that they typically dry up during the summer months. You can check the spring status here https://www.parc-du-vercors.fr/info-sources.
• TRANSPORT: In Corrençon-en-Vercors, we parked in this free public lot near the trailhead (https://goo.gl/maps/zUR4HM3uf1aiEQjDA). From Châtillon-en-Diois, we hitched-hiked back to our car. It took five separate rides but was pretty easy, relatively fast and a fun way to meet some interesting people.
