WARNING for those who ride big/wide bikes (GSs!) as well as those having side-panniers on!!!!!
I was there recently with my 701 with Giant Loop over the luggage frame on the back, so a bit wider than without luggage ...... and at one point, where concrete barriers have been put up across the entire road, one
has to ride over a narrow edge, ledge rather, which is a steep drop-off into a river I think.
This I would NOT try with panniers on my bike, and perhaps not even with a boxer - it is THAT narrow!!!!
Realize this please, and tell others
