There are mines local which we revisit regularly, mainly when we break somebody new in with an easy one. But if we're going to travel 2 to 3 hours to Wales then we like to try and complete the whole mine system then once done, find the next location, especially if its difficult to access like this one. I have the key to the largest slate mine known in europe, which also holds the go-below adventure, we are yet to explore every part due to its size so that will be the next visit if not the next couple!
