This magnificent walk crosses an extremely beautiful region, one of which is the spectacular lapies formation between Pierre du Moëllé and Tour de Famelon. The lapies were formed by dripping rain drops over centuries and confer a lunar look to the region.
The rocks of Tour de Famelon, whose singular relief earned it the name «Alpine Sphinx», are sea and lake sediments which, on solidification, have acquired a distinctive grey-red hue found nowhere else in the vicinity.
