In reply to ledifer: really? The place for via ferratas is in the dolomites within an historic context. I don't say that from some moral high ground, but simply because the VFs in italy were put there for a reason, and it lends great authenticity and are utterly uncontrived. They are genuinely a great way to see the mountains. At cheddar that simply wouldn't be the case, especially in some mucky quarry, although if they had to do it they should do it in a quarry. There are plenty of ways to see the awesomeness of cheddar without resorting to a vastly intrusive installation which would change the gorges atmosphere to its very core.
