Cerrig Llwyddion is really two lakes for the price of one ticket — an upper pool that holds a sparse scattering of small wild browns, more a curiosity than a destination, and a lower lake with rather better sport, brown trout running up to a pound for anyone patient enough to work it properly. Both come under the same Claerwen-inclusive permit as the rest of the Rhayader club's upland water. The sensible plan is to treat the upper as a look-and-learn stop on the walk in and spend your actual fishing time on the lower. Remote, quiet, and entirely without pretension — which describes most of this stretch of moor rather well.
