Caseg Fraith


A top quality grade 6 circuit with a diverse range of problems, including the brilliant Caseg Fraith Arete and some fine slab lines. There are also a few harder steep problems and an impressive, futuristic project. The landings are generally good, and the rock is a superb fine grained tuff reminiscent of good quality sandstone.
The adjacent Gallt yr Ogof boulders has several fierce test pieces; there is also a recently developed highball wall with an impressive 7B+.


The landings are good, although after heavy rain the area below the steeper right hand boulder becomes waterlogged. There are no major seepage issues, save on the odd problem, such as Suck my Slab. The open aspect and clean rock ensure that the problems dry quickly after rain. In summer the bracken can obscure the vague path leading to the upper problems.


To reach the boulders from the Gwern Gof Isaf campsite walk up and over the ‘A’ frame stile on the left, and head back rightwards to the slightly hidden micro crag immediately behind the Caseg Fraith university club hut. Further interesting problems can be found by wandering up the right side of the Braich y Ddeugwm ridge.
To reach the Gallt yr Ogof boulders walk down the old road (towards Capel Curig) for a few hundred metres until you spot a prominent boulder on the right, 150m from the road.
