Navigation Quarry is a pleasant climbing venue located on moorland high above the valley. This is one of the older cragging spots developed on the sandstone and consequently some of the routes are not full clip-up sport routes. Bolts have been kept off of the established trad lines, but there are still plenty of excellent fully bolted sport climbs for those up to them. Not all of the established traditional lines are included here and only fully bolted sport pitches are given sport grades.
