Access by car.
The village of Prélenfrey is about 30 kilometres south of Grenoble. After the village, take the Bordeaux forest road and follow it to its terminus, where you will find a car park.
(S/E) From the car park, continue along the forest road, which turns into a marked hiking trail, and follow the signs for "Pas de l'Œille".
(1) Shelter known as "Baraque de Clos". The path rises above the forest and follows the slopes of the Vercors, where ibex roam.
The final climb to the pass is more difficult and you may need to use your hands, so be very careful.
(2) After a 2-hour climb, you will arrive at Pas de L'Œille and discover a magnificent panorama of the Trièves.
Allow 1½ hours to descend via the same path to return to the car park (S/E).
