The Woodland Trust who own the site do not allow access for climbing on this venue due to concerns they have about possible damage from climbing activities to the nationally important flora and the sites' designation as an SSSI.
The Woodland Trust state that :-
“Marl Hall Woods are owned by the Woodland Trust. Whilst their woods are open to the public for quiet enjoyment, it should be noted that Marl Hall Woods form part of Creuddyn SSSI / Creuddyn Peninsula Woods SAC and as such, third parties who wish to undertake work notified as an operation likely to damage the special interest (which would include any vegetation removal or crag ‘development’) would need permission from the owner to deliver works in accordance with written consent from Natural Resources Wales. This consultation process enables an assessment to be made on the likley impacts of proposed works on the rare plant populations, woodland and grassland habitats that occupy the site."
