It’s a great rock for climbing on: lots of positive, incut holds; many jugs; resistant to polish; and surprisingly solid despite some appearances to the contrary (and despite the experiences you might have had on Red Wall!), and there’s a broad swathe of the stuff spanning the Durance Valley around the village of Prelles. This is a great complement to the predominant limestone (not to mention the conglomerate on Mont Dauphin and the granite of Ailefroid that make the area such a great spot!).
We spent a few days enjoying the routes at Rocher Baron and Casse de Prelles, both of which have featured before on the blog, (use the “Search” box to find more) so here are some photos and highlights.
