Approach
Park where the Ruisseau des Minires crosses the N666. (Take a look at the Chantoir de Secheval if you like.) Drive/walk up the road to the right of the ruisseau, stream upwards. After a turn or two it should start following the ruisseau again, and the rock can be seen to the left after 600-700m. When the water is low it is easy to acces, otherwise good luck jumping.
