Owned and managed by the BMC for climbers, there are very few issues at Bwlch y Moch. However climbers are asked to observe a few points. On no account should the fence at the top of the crag be crossed - all of the land at the crag top is privately owned, including the cliff top path and an agreement is in place with the neighbouring farmer for a permissve path along the cliff top. There is no descent either behind the crag or to the east. If choosing to abseil ensure that a sling is placed around the tree to prevent damage and that you do not cause inconvenience or a hazard to other climbers -"look before you chuck" is the motto here! None of the abseil slings or fixed belays are maintained or inspected by the BMC -so please ensure that you are satisifed with their safety and suitability before using! Camping is not allowed at the crag and there are no toilets at the site, closest public toilets are in Porthmadog itself.

Warning - August 2022 There are reports of a rockfall affecting the first pitch of the route Hail Babe, on Vector Buttress. There have been rockfalls here in the past, so please excercise caution if climbing this route.

CRoW Information

Will be dedicated as open access under CROW by the BMC.

Group Advice

Suitable - but can be very busy, especially at weekends, and a lack of low grade single pitch routes can make it difficult for novice groups.

Area information

A wide range of cliffs - mainly traditional and multi pitch inc. the popular Llanberis Pass, Idwal Slabs, Clogwyn du'r Arddu and Cwm Silyn cliffs, but also outlying outcrops such as Carreg Alltrem. Many crags are on CROW access land - but not all especially some of the outcrops which lie on private enclosed land. Most of central Snowdonia is both designated an SSSI and also is an European Special Area of Conservation on account of the upland habitat and associated geology and plants found here.

Its worth noting that there is a nest of honey bees at the end of the first picth of Hele Bebe. The bees are not agressive and a belay stancd can be found to the side of the tree out od their way. It might be worth any local bee keepers and also climbers investigating the feasibility of removing the nest.

Path to bottom of Grim Wall Direct area has been changed to slightly higher elevation, due to severe erosion of previous section
Please don't climb on the Oakover slab until the Tawny Owl has finished nesting in the old tree stump half way up the slab. It should be finished by the end of May 2021 because the chicks tend to leave the nest after five weeks. All routes pass too close to the stump and the abseil goes right past the stump too. The adult flew out of the stump on Axeover as we climbed past yesterday (25 April) so we walked off, rather than abseiling. It would be a real shame to scare away the parents and leave the two chicks to starve to death.
