Signposting etc most definitely puts me off. It's one of the things that puts me off the Lake District for example, you see these twee wooden fingerposts everywhere. They're certainly urbanisation in my view.
Been to Aber Falls lately? The restored path to them is now nearly as wide as a road, extra steps prevent legs from having to stretch too far, and just downstream of the falls there's a smart wooden footbridge to help you over the river without any danger of getting your feet wet.
I've walked in most parts of Snowdonia over the years, but I've done Snowdon itself the least. The national park is a big area, and while I don't mind meeting the occasional other walkers, there's no way I want to be in a two-way crocodile of people, as I experienced on the Llanberis Path on a September Wednesday.
On a camp site last year, I came across a small group of twenty-somethings who had travelled from South Wales specifically to go up Snowdon. They didn't know where it was, where to start from or how to get there, and I had to give them a brief summary of the various routes!
