Fascinating, bizarre and wild, and particularly pleasant in the summer months since the climate is humid cool and promotes biodiversity. The gorge winds into the valley, it starts innocuously at the bridge that leads over the Valsura river in Oberlana. The foot path is secured with hand rails and surrounded on both sides by rocks of quartz porphyry, gneiss and granite that are competing in height with spruce, maple, ash and beech trees. We encounter hazel bushes and various species of meadow, fern, grass, moss and flowers on our walk. Tunnels, rope bridges and a waterfall at the end of the gorge: once you are immersed in these trees and bushes you don't cease to be amazed!
