Quarries are usually depressing holes in the ground, but Millstone is the exception. With smooth walls, soaring grooves and inspiring crack-lines, it is the greatest of all the gritstone quarries. The cracks here span most widths from tips to fist, though luckily there are no dreaded off-widths. Many of the routes were originally done as aid climbs up spidery cracks, the repeated placing of pegs widened them enough to allow thin fingers and pointed toes in and also to provide protection from wires. Fortunately the climbing is not just about cracks, there are also many fine corners and aretes formed by the careful quarrying of the various bays. The section from Green Death to the Keyhole Caves couldn\'t have been better designed if a climber had been in charge of the work.
It is worth pointing out that some of the exits can be dangerous where weathering has left \'chest-of-drawers\' finishes which require care; it is a good idea to place an extra runner or two below the top-out and ensure the second is on-the-ball. Wearing helmets here is a good idea too.
