The frogs reign. There are many surprises in a mountain hike: after an ascent suddenly a valley, a waterfall and a stream occur, crossed by a wooden bridge, larch trees, votive chapels, steep ravines, small lakes among pasture and roche moutonnée, aerial panorama, showy blooming.. but be careful: the frog life need to be respected: do not collect tadpoles!
If you want, it's possible to climb up more over the Bardoney valley and reach the Loie lake to then go down to Lillaz on a route, sometimes steep, but definitely panoramic.
