An advisory body to Unesco branded the idea by the owners of Elterwater slate quarry in the Langdale valley ‘adventure tourism’
An international heritage body has condemned plans for an underground zip-wire attraction in the Lake District as a “theme park” which imperils the area’s “tranquil and contemplative” quality.
The owners of Elterwater slate quarry in the Langdale valley want to create an immersive heritage attraction by opening up caverns, some of which are inaccessible or were once mined.
