In reply to Zgemba: it is a little tricky there. Because its within the bounds of a Unesco world heritage site and the national park, strictly speaking permanent installations are strictly prohibited, including the bolts that are already there. They have been placed by individuals. If I was going to replace anything, I won't be broadcasting it here! And yes, its stupid, but knowing how local politics works, I won't be trying to push anything through legal channels as it will just be flatly refused. Unfortunately they don't understand or I get the impression want to understand climbers. But you never know... Things might change. There is certainly budget for improvements to the amenities of the gorge funded by local government, but this is mainly allocated to "standard" tourist projects. For example there is talk of a gravity bike park in the valley. We'll see...
