Officially there is no access permitted away from the PROW or bridleways.
Access to climb Trango Towers/Peppermint Pig areas is sensitive as it lies within the inner perimeter of the power station - climbers are occassionally asked to leave this area by security staff. Access to Rainbow slabs and surrounding areas is only possible from the Llanberis side but access from Nant Peris (Pass side) is striclty not allowed.
This area includes all of the lower part of Dinorwig Slate quarry, including Rainbow slab area, and the levels opposite (Rainbow Walls). The Lower Dinorwic quarries are all on land owned by First Hydro Company (FHC). FHC have to comply with the Mines and Quarries Act. This means providing a properly maintained barrier to prevent members of the public from falling into the quarries. The company are repairing fencing in the area and employing additional signage to emphasise the dangerous nature of the quarries. There is no formal permission to climb or walk in the quarries away from the public footpaths and if the secutiry staff carrying out routine patrols, see any members of the public (including climbers) away from the public rights of way they will be asked to leave. Please follow their instructions and do not create conflict if this is the case. Please respect the environment of the quarries, do not damage any fences, keep dogs under control and take all litter home with you. In order to protect the current sensitive access, climbers have agreed not to climb on any of the levels below the Rainbow level or on the large tower overlooking the power station buildings.
