On the boulder E of the topo du Puiselet Paradis. Standing start and exit in Le Mur du Paradis (raccourci).
PS: this problem was known as "Le Mur du Paradis" for many years. It was tried by many but only 'climbed' in 2006 in an unconventional way (with the help of the smaller boulder in the back). Nicolas Januel did the first real ascent in 2022.
