John Henry Quarry - In-di-go (above climbers head) © cmgcmg
Worth a visit if linked with Hobson Moor quarry. Most routes are in the low to middle grades up to 25m high. Slightly vegetated/damp in places, choose a dry spell. The best routes are between VS and E2, all of which are well-protected and sound.
The rock is clean and solid, except for where it isn't, and many routes are climbable after a day of dry weather. Some lines take a ton of seepage, but they should be obvious when you turn up. As the place is a sun trap, it is also a midge trap, and if there has been rain and the day is fairly windless, you'll have a Scottish midge experience.
On the eastern edge of Tintwistle on the A628, the 'old road' branches off leftwards. 100m from the A628, a grassy track runs into the quarry.
