Right problem on the boulder of The Seneca Effect, 50m above La Route du Milan, in the western part of the sector. Standing start without crash-pad at a green arrow and exit on the slab above.
Park the car on the D301 after La Croix du Grand Veneur, follow the path on the right and then La Route du Rapin. The South face of the boulder in visible on the hill when that one meets La Route de Milan.
