My wife and I visited this gorge 2 years ago. Besides the interesting gorge, also a nicely arranged forest educational path with an excellent viewpoint right above the road (hut with panoramic picture of the Karnics) and a nicely renovated water-powered saw at the parking. At that time the left harder variant in the gorge wasn't there yet. On the return, we viewed in the museum in Kötschach also a very extensive and interesting display of WWI battles, which also covers the Soča front.
