The cliffs of Orque (or Olque, depending on local toponyms) form a real rocky front overlooking the Haut-Languedoc: a limestone wall about 200 meters high, leaning against a plateau perched around 800 meters, north of the Caroux and Espinouse massifs.

A very pleasant climb from Lamalou-les-Bains! The beginning is (very) steep (7-8% average over quite a few kilometers), but it becomes more rolling after that.

Ignore the path on the right, which starts opposite the refuge in a forest path, to continue straight on the track for 100 m. Turn onto the path on the right. It runs along a balcony and leads to the orientation table.

I was thrilled one day when I saw the Pyrenees with their white peaks on the horizon. But the locals were less impressed, because it was an omen. The next morning, a torrential rain started.

The Roquandouire portal seems to be the work of humans. This door of stones, is in fact the result of erosion. This is a characteristic feature of the place and frequent on the Espinouse.
