In that limestone country there are a few long clefts in the earth including Deep Dale, Horseshoe Dale and Back Dale. They are somewhat hidden from neighbouring roads. It would be easy to speed past them and not know they were there.
The aptly named Deep Dale appeared to be a haven for wildlife with unusual butterflies dancing above undisturbed beds of nettles, thistles and wild grasses.. I climbed up to a cave and even went inside. I am not sure how natural it is for there is much evidence of historical lead mine working in north Derbyshire. Later I discovered that it is called Thurst House Cave.
It wasn't the longest walk - no more than four miles. I didn't see another rambler and the paths I walked seemed little trodden. Where I parked at Brierlow Bar there is a bookshop and cafe. I had seen it but I had never ventured inside before. Considering how isolated it is - way out in the countryside - it was surprising to see what a wide range of books it sells - including "How To Live Vegan" by Bosh!
