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.

The Col de la Croix de Mounis is one of those passes where you don't just cross a slope, but a true border between two valleys. Perched at an altitude of about 800 meters, in the heart of Haut-Languedoc, it connects the Mare valley to that of the Dourdou. For a long time, this pass was a strategic crossing point between Lacaune and Saint-Gervais-sur-Mare. Before modern roads, it was already part of a local circulation network, used by muleteers and stagecoaches, where villages, markets, and valleys were connected via routes dictated by the terrain. The current road still retains something of this logic: it doesn't cut through the mountain, it goes around it and "negotiates" it.

One of the 3 magnificent lakes in the South-East of Tarn. Although artificial, it catches the eye with its wild appearance. Worth seeing on sunny days or to escape the heatwave

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.
