A fine cliff in a quiet and very sunny setting. Many of the routes are hard and steep, though there are a few easier offerings on the slabs to the right and under the central roofs. Seepage is a problem after wet weather and there are a few too many chipped/glued holds on the hard routes for some folks' liking.
The crag isn't a good summer venue as it is just too hot, though the most overhanging routes do get some shade. The central cave gives dry-in-the-rain climbing although there is some seepage. It is a good winter venue as long as you aren't after the tufa routes.
From Tarascon-sur-Ariège, drive to Niaux on the D8 and turn right towards Alliat and Génat. Continue though Alliat and on up a series of hairpins to a left turn, 3.2km after leaving Alliat. Park at the end of this in the quarry - just past the farm (which also has a café and sells great fruit in the season). A good path leads from the far end of the quarry, diagonally up to the cliff.
