Ten limestone walls and buttresses consisting of mainly sport climbing, the best of which are at Compact Wall and the steep side of the large main quarry. There are some lower grade trad routes on Railway Buttress. All routes at the Trevor area are single pitch up to 17 metres.
Follow the Eglwyseg Valley road from Llangollen until a turning, signposted 'Panorama' appears on the right. Follow this for a mile, ignoring a sire road dropping off to the right. Continue until a large layby is reached on the left. For Trevor Quarry, approach is made via the steep scree slope above the layby. For Compact Wall and Railway Buttress approach is made along the obvious incline for about 400m leading back up the valley and along a path at the foot of the quarries.
Note: further up the road from the layby there is a hairpin bend with a track leading to Trevor Quarry. Do not take vehicles up this route, since the farmer uses this area for sheep grazing.
Due to the site's designation as both an SSSI and an Eurpoean Special Area of Conservation the landowner has been informed by Natural Resources for Wales that he cannot allow vegetation clearance, rock clearing or drilling on these rockfaces. Therefore until please refrain from further new routing in this area.
Dates: 15 February to 15 July
Reason: Nesting Birds
Peregrines historically nested on the far left hand side of the crag. Signs will be in place on the apparoach path if this is the case but the birds have not nested here for over 10 years.
There are no seasonal restrictions currently in place for 2021 on any of Trevor rocks sections.
