Near the head of Borrowdale at Seatoller, the B5289 road cuts west, snaking up and over the dramatic Honister Pass, en route to Buttermere. At the top lie the unassuming buildings of Honister Slate Mine – an unexpectedly great place for daredevil adventurers with its deep mine tours and mountain activities. Come suitably clothed – it’s either wet or windy up here at the best of times.
