Col du Gratteau - Crêt de l'Œillon - Trêve du Loup circular

A short hike in the Pilat Massif with plenty of shade. The route is not too difficult and offers beautiful views of the Rhône Valley, the Vercors and the Alps, weather permitting, as well as the Monts du Lyonnais in some places and the Gier Valley.

Description of the walk

Coming from the Rhône valley, head towards Pélussin. Then head towards the Col de l'Œillon, passing through the small pass of Doizieux, known for its inn and car park for hikers. Continue towards the Col de l'Œillon and, on your left, you will see a car park for hikers and the Parc de Pilat Aventure. Park in this car park.

(S/E) Leave the car park and take the forest road that descends slightly towards the Parc Pilat Aventure, passing close to the Chapelle de la Magdelaine (where masses are held from time to time), and stay on the forest path.

(1) Leave the forest road and take the path that climbs gently to the right. On this route, you also have the option of passing by the Trois Dents, but for this hike, we will pass below them.

(2) Keep to the right, leaving the path on the left, go around the Trois Dents in a wide curve to the right and continue straight ahead until you reach an intersection.

(3) Continue right on the path that climbs up to the Col du Gratteau viewpoint.

(4) Take the opportunity to admire the view and enjoy a short break. Leave the car park and head towards the Col de l'Œillon. Be careful, just as you leave the car park, take the path on your right which climbs through the broom and a few blueberry bushes, a well-marked path on the ground. Follow it, pass higher up at the foot of the tower, admire the view of the Trois Dents and, further on, rejoin the marked Trois Dents trail. Turn left towards Col de l'Œillon and you will come out onto the departmental road.

(5) Cross it with caution. Opposite, there are two trailheads: take the one furthest to the left, which climbs through the fir trees. Stay on this trail, crossing the road, and continue to the Crêt de l'Œillon car park. Head towards the burnt hotel and Crêt de l'Œillon. Pass to the left of the antenna: you can also pass to the right, as both paths lead to the orientation table just behind.

(6) Take the path on the left that descends, cross the unstable scree (be careful), and arrive at the bottom to find a marked path. Turn left, pass the paragliding take-off point, continue on this path and arrive at the burnt hotel. Continue straight ahead on the ridge (view of the Gier valley) and arrive at Trève du Loup.

(7) Turn right towards Chaux de la Madeleine and you will soon reach a forest path. Turn left and stay on this path until you reach a fork.

(8) Take the path that descends to the right until you reach another forest road further down.

(9) Turn right towards Col de l'Œillon, then take the first path on the left which descends, still through the woods, and leads back to the Parc de Pilat Aventure car park (S/E).

Notes

Be sure to bring water with you, as there are no places to quench your thirst along the route unless you stop at the small pass of Doizieux inn if it is open. Wear sturdy shoes in certain places: there are quite a few unstable rocks. Walking sticks can also be helpful on descents and ascents.

Always be careful and plan ahead when hiking. Visorando and the author of this page cannot be held responsible for any accidents or inconveniences that may occur on this route.

Worth a visit

Pélussin: a pretty village to visit, stop for a drink and, if you have a little time, take the opportunity to visit the viaduct, etc.

If you have some free time, there is a tree-top adventure park near the route. There is a lovely view of the Rhône valley; once you reach the Col du Gratteau, you can sit down and admire the landscape. Further along the route, there is an orientation table to the north of the Crêt de l'Œillon relay antenna. And the Crêt de la Perdrix

Very beautiful hike. Great view at the foot of the tower WITHOUT PEOPLE on the Three Peaks and the Alps.
BEWARE: there is a very rocky section (short) after Crêt de l'Oeillon, so walking sticks are recommended if possible.
Thanks to those who mapped it out and to Visiorande for the guidance with the app.

A very beautiful hike with magnificent views and a great variety of terrain. It should be noted that there are some very rocky sections, which are more difficult to navigate, so good footwear is essential.

A very beautiful hike! There are frequent viewpoints along the route. No tarmac (except when crossing roads). Varied terrain: grass, forest paths (more or less stony), small paths through broom, scree (well signposted). Walking shoes highly recommended. For a Sunday, there weren't many people on the route, except at the Crêt de l'Oeillon, where many visitors come to enjoy the view.

Possible variation of this lovely walk with a more aerial route (several exposed sections). Leave the trail on the left just before point 2 towards the Pic de Midi. Climb up the Crête des 3 Dents ridge. Take care in strong winds or gusts. Then rejoin the trail at point 5. Beautiful views of the Rhône valley in a mountain setting.
