Approaching the Rastenbach gorge, on your way down from Altenburg/Castelvecchio to Lake Kaltern, it suddenly gets really cool and dark. Your steps become more cautious, as if you’re being careful not to disturb the peace. Silently, you look around and enjoy the wonderfully refreshing ambiance. How reassuring to know that the wooden stairs and bridges are reinforced and properly secured. When you get to the bottom of the trail, you are welcomed by a sunny field and Lake Kaltern.
