Restricted Access

There have been serious problems here in the past but access appears less problematic providing climbers keep a low profile. The quarries are owned by Gwynedd Council who make it clear that there is no offical access due to public safety reasons - there are high fences and signs prohibiting access, but there have not been any reports of practical access problems for many years.

In early 2017 planning permisson was granted for a new hydro-electric power station on the site. When works starts on this (unkknow time-scale) its likley that access to some of the quarries will be permenently lost, especially to Mancer and Film Set Quarries as these will become flooded to produce a holding reservoir.  

Seasonal Restrictions

Dates: 1 March to 30 June

Reason: Nesting Birds

- Due to nesting Peregrines and Choughs (both species have legal protection under the Wildlife & Countryside Act),  some climbing in the Gideon Quarry (all routes on Gideon Terrace and Cracking up areas) is restricted from March 1st until the end of June.


2 pitches.

2) 6b, 33m. Climb The Bone People to the second bolt, then swing onto the exposed right wall. Pass two bolts to a sloping foothold and continue up a small groove to the roof. The crux is gaining the right arete at the roof. © Rockfax
