Crag features

The new Snowdonia South Bouldering guide is in preparation and should be ready Spring 2021. Cae Du is of course included with 100 boulder problems named and graded Font style with excellent photo topos and action shots . The guide details many new areas in south Snowdonia including the LLwyngwril bouldering zones and the hillside above Llwyngwril where Llwyngwril locals have been busy .Any one who would like to see their action shots in the guide please mail to

Cae Du is an excellent sundrenched sea cliff bouldering venue tucked away in south Meirionnydd about 90 minutes drive from Llanberis. It is located below the farm and camping site of Cae Du on the A493. It's a very quiet area that is only occasionally used by local outdoor groups.

This is a great place to hone your technique and develop power as slopey rock and directional holds abound. If you are just starting out or looking for a chilled day, don't let this put you off since the area excels in the friendly range of V0- to V3. Also, the beach setting creates a relaxed and fun atmosphere.

The crags are tidal and the rock is washed clean daily however, the pebbles under the problems are sifted and rearranged by the tides to create new challenges or occasionally make some problems easier. The grades given therefore are only approximate.

Approach notes

A few miles north of Tywyn in the village of Rhoslefain turn off at the Cae Du farm corner . Coming from the north it is just south of Llwyngwril village and is clearly visible from the road as you apprach Cae Du corner .From Aberystwyth allow 1 hour in a car ,from Dolgellau allow 25 minutes.

The campsite was shut when we went, and there was a sign saying no day parking. Suggest call the site first to clarify access.

Accessible 5 hours either side of low tide.
Pay £4 at the farm to park, shut the gate behind you and leave your car beyond the bridge. The North end of the crag (Area 1) can be reached by walking down the beach or walk on top of the crag for about 400m to an old quarry path and follow it down to area 4.

To save the cost of parking you can park at Tonfannau train station ( or if on the train pleae note this is a request stop only ) , walk down to the shore and stroll along the 1 km to the boulders for free ! And its a lovely walk .

Parking is now 2

there are several places called cae du but once you add the word "tywyn " or "bouldering " to your search in Google it brings you to the correct place

Are you sure the location for this crag is correct? because when you google "Cae Du", it finds a place in north wales nowhere near where this is marked?
