As the Covid-19 lockdown eases, access for climbing is opening back up, subject to some measures and restrictions depending on where you are going. Please make sure you have read and understood our current advice before heading out and apply it alongside RAD advice to ensure access issues don’t develop.

Castle Inn Quarry

A south facing limestone sports venue, located above a car park at Llysfaen, near Colwyn Bay. The crag is part of the Mynydd Marian Local Nature Reserve and is an SSSI.

Crag information
Climbing Area: Wales Rock Type: Limestone
Importance: Regional CRoW Land: Yes
Ownership: Local Authority No. of Routes: 52
Within National Park: No Year Developed: 1959
Grid Reference: SH889773

May 2020. Conwy Council have informed us that the car park below the cliff is currently closed and part of the main face is closed for climbing and is cordoned off due to unstable rocks/rockfall issues.

The owners (Conwy Council) have in general no problems with climbers using this site, however developments to the west of the main cliff have involved gardening and rock removal on a site known to be important for a nationally rare butterfly, the Silver Studded Blue. Climbers are asked to minimise gardening and vegetation clearance at this location, which is an SSSI, and avoid damaging the grassland below the rock face. There have also been concerns that trees and other scrubby growth have been cut on the east side of the cliff. It is important that no tree or vegetation clearance takes place without prior approval from the site warden, contactable via the BMC.

The right hand side of the car park has been sold to a private owner, and climbers should not enter the fenced area or land belonging to the old Castle Inn.  However the cliff face is still owned by the council and climbing is allowed.

Climbers need to be aware that the cliffs are very close to and overlook residential areas and any undue noise or unsociabe activity will cause anatgonism and possible access issues. This is particularly true for larger and organsised groups - this is not a a school playground, so instructors and leaders, please manage your groups accordingly! 

At busy times parking can be a problem and complaints have been recieved abourt climbers blocking the lane below the crag - consider going to other sites if this is the case.  It's strongly recomended that groups in minbuses or larger vehicles do not park below the crag but instead use the Mynydd Marian Nature Reserve Car park - and approach the crag by a short 5min walk across the meadow above the crag.  Map ref for car park SH893772.


Parking and Approach

Please park in the Mynnydd Marian Nature Reserve car park and not directly below the cliff.

Group Advice

Suitable for small groups only - all the routes are sports climbs, and top roping directly through the bolts is to be avoided to minimise wear on the bolts.

Instructors and group leaders need to be aware that the cliffs are close to and overlook residential areas and there have been concerns by residents about nosiy and unruly behaviour by climbers. Parking is also limted and there have been issues with minibuses impeding access on the approach lane. 

It 's strongly advised that groups in minibuses park at the main Mynydd Marian Nature Reserve car park at SH 893772.  This is located by following the lane beyond the crag, in an eastward direction, until the lane veers left (north) and after half a kilometer the car park is on the left. It is only a very short 5 mins walk across the meadow to the crag from here.

Closing the entire main face all the way round to Driving the Dumper is totally disproportionate because the rockfall came from the known loose gully between Finale and School Mam. This is an important crag and the BMC needs to make every effort to get the main face re-opened. Conwy Council's own interpretation boards list climbers as key users alongside dog walkers and nature-enthusiasts, so they have no excuse for restricting access beyond that which is strictly necessary.
