May 2017 Update - a substantial rockfall has occured on the tower (known as Trango Tower or Y Ceiliog) containing the Plateau Slabs routes. As a result the landowners have cordoned off the whole Plateau/Peppermint Tower area and substantial ground works are being carried oput by contractors.
Access to climb at these venues (Trango Towers/Peppermint Pig areas only) is no longer possible. Access to Rainbow slabs and surrounding areas from the Llanberis side remains unchanged but access from Nant Peris (Pass side) could be restricted when contractors are carrying out work.
This area includes all of the lower part of Dinorwig Slate quarry, including Rainbow slab area, and the levels opposite. 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. 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.
