This crag was said to be used to hang criminals on the top of as an example for all to see. Luckily this isn't done much these days and the top off the crag is now just a popular spot to watch the traffic (jams) on the A55. The routes themselves are on perfect solid rhyolite with plenty of positive holds and amazing pockets.
Re-equipped in 2020, the crag now gives a very good set of mid-grade sport climbs.
Exit the A55 at junction 17 and drive towards Conwy on the A547. Cross the railway bridge and immediately turn sharp right into a cul-de-sac road which leads towards a small industrial estate south of the railway track.
Park about 100m down the road, then walk back and follow the A547 towards Conwy for about 200m until a stile on the right leads onto Conwy Mountain. The steep grassy path leads straight up until a fork left can be taken above the crag to gain the summit cone, adorned with eponymous notice board and various iron stakes. Access the base of the crag by heading down the far side of the summit to a small grassy shoulder, from where a mini path leads horizontally left to a small notch and old fence. A fixed line is in place along the exposed ledge at the base of the cliff - all quite exciting.
An alternative approach for locals is to follow the North Wales Path from Mountain Road up onto Conwy Mountain and head right towards the Notice Board. Parking is limited on Mountain Road.
