Ludnica,
Because of these two signs I went to learn Italian and now I've been diligently learning it for 9 years and read and understand all Italian signs and plaques in the western Julian Alps without problems. My colleague translated that inscription back then as if there was an improvised bridge over the river, ha,ha,,,.. At Norina you need to watch the precipitation at the time you're heading out. If the stream level is too high, you can't cross it, otherwise water just over the ankles. Towel mandatory with you. There was a sandy landslide 10min from the car downhill before the stream, which was extremely annoying and in 2017 had one rope fixed, more for calming the nerves than anything else. Had to step wide and boldly into the sandy mush which went about 20 m down to the stream.
