How to reach : From "Le Rozier" (main street) drive east on road D996 into Jonte Canyon to La Caze for 7km and turn left on road D63. Drive up this road 10.7km and turn right (south) toward La Retournade. Drive this little road 2.8km and turn left toward Les Herans. Drive to this hamlet at the end of the paved road and proceed 1km by dirt road (passable for all cars) to the abandoned hamlet of "Les Horts".At this point you will make a very sharp left turn at the yellow sign indicating La Jonte-Meyrueis. However, it is best first to procced on the main dirt road for another kilometer and then scout the area south with binocular below and to the left until you spot the arch. This way you can scout the route. Back to the aforementioned turn, drive or hike down this 4WD road (passable with passenger car going slowly) for 1km to a spot where you can turn around and park at a point where a rough old road goes very sharply down to the right. Then continue on the main road by foot (south) for about 350 meters to the obvious curve to the left. From there look down the slope to the southwest along a very blunt ridge to a clearing on a promontory. Bushwhack down the slope to the small meadow (about 200 meters). Once you are here, find your way south through rock masses and a grove across the promontory, descending three level terraces to the splendid arch sitting on the side of the cliff.
