Osian Parry has been busy, adding five new lines to the Cwm Dulyn boulders. Hardest of the bunch is Sanctaidd yw'r Nos (8A), which can be found on the steep boulder right on the lake side, i.e. 20m below Reu. Start left hand on a good low gaston and right on a small crimp. Two crimpy moves lead to the lip.

Tawel Nos (7C) start hands matched on the Sanctaidd yw'r Nos lefthand start hold and climbs up to finish in the same place.

Dagrau'r Glaw (7C) tackles the steep narrow prow 20m behind Reu. Start sitting, left hand on the obvious crimp and right on a slopey pinch. Narrow compression moves lead up the prow.

Goleada'r Gogledd (7B+) surmounts the steep roof 5m above Reu. Start with both hands on the obvious block wedged under the roof. Climb directly through the roof to a big jug. Easy moves lead to the lip and top out round to the right.

And lastly, Dulyna Fi (6C+) scales the left arête of Dulyn Wall, from a sit/crouch on two crimps. Ben Ellis did the first ascent of this striking line, and Osian added a low start which goes a 7A+.
