Well, the path through the gorge is actually closed, and after ignoring the 'no entry' sign and spending one hour there, I know why. I almost got killed a few times by the falling icicles! The footbridges were slippery in places, but at least I could take photos with a tripod as there were virtually no people around. Actually, I did meet a few other 'trespassers' and they were all foreign tourists! Needless to say, they all loved the place.
