Group Advice
Located in a private forest area, the crag is frequently used by groups. However in 20017 the woods appear to be managed by a private agency for the absentee owners. In additon the woodland managers do not wish groups to be in the woods when felling/contractor operations are underway (usually mid-week only).

Permission to wild camp
Wild camping is not permitted anywhere in Eryri without prior permission from the landowner or farmer. Camping in car parks or on roadside verges is not allowed at any time.
The National Park owns little land; therefore, we cannot give consent for this activity on other people’s land including agricultural land, sate or private forest, National Trust property, riverside or coastal areas or land designated under the Countryside & Rights of Way Act as ‘open country’.
[…]
The law and further information
In unfenced isolated upland areas, the access land provisions of the Countryside & Rights Of Way Act (CROW) specifically state (under the list of restrictions in Schedule 2{1} s) that wild camping is not a permitted activity unless granted by permission.
