Overview


The aptly named The Diagonal (Severe) takes an obvious line up a large diagonal crack, which slants up right from the base of The Diamond Wall to the top of The Bastion Face. The route is short but atmospheric, and although it might not be the greatest route on Craig yr Aderyn, it takes place on some of the crag’s cleanest, soundest rock, and is an excellent starting point for anyone climbing there. The 37 metre route is usually climbed in two pitches, however it can be split into three by belaying on a ledge around 10 metres below the usual belay point. This allows the climbers involved to communicate more easily, as since the route was first climbed, a tree has grown around the usual belay point, obscuring the climbers' view of one another and muffling their calls.

FA: A. Howard and D. Davies (Alternate Leads), November 22nd 1964.

Most visitors to Craig yr Aderyn will approach the rock from the east, if you have to approach from the west, then you clearly know the area well enough already, and therefore don’t need a section such as this to help you get there. So, if you are coming from the east, you need to turn off the A470 at the Cross Foxes Inn junction (SH 766 167), and drive south along the A487 for some 6km to the junction for the B4405 near the Minffordd Hotel (SH 732 114). For those familiar with the area, this is the same turning as you would take for the car park on the southern side of Cadair Idris where the Minffordd Path starts. Drive along the B4405 as far as Abergynolwyn (SH 677 069). In the centre of the village there is a crossroads, turn right here and drive north up a narrow unclassified road to another set of crossroads marked by a public phone box (SH 662 079). Turn left here and drive west along another unclassified road. After a around a kilometre and a half the road reaches Craig yr Aderyn and passes along the base of its north face, There are various lay-bys along the road where parking is available, the best ones for this route are located just beyond the junction at grid reference SH 643 071. The start is at the bottom of the obvious crack that the route ascends.

Route Description

Pitch 1 (26m): Take a line just below the crack to a small ledge, the first 9m of climbing is poorly protected so take care. There’s a friend jammed in a crack on the left side of the ledge. You can belay here if necessary. Climb more in the crack to an awkward final move and another ledge where you can build a boulder and tree belay. The final moves can be a bit vegetated, particularly in summer.

Pitch 2 (11m): Move easily right over some protruding boulders and a stance on the buttress then climb to the top via a clean cut groove on the left.

Descend via a narrow ramp which can be accessed by walking a little further uphill and slightly to the left.

Essential Gear

A single 50 or 60m rope will be fine (you may want to use a double or twin but its not essential) a moderate rack of nuts, hexes and maybe a few cams. Also be sure to carry a selection of slings and screwgates for constructing belays. The route is best done in rock shoes as boots would be way too cumbersome. Naturally you will also need all the other paraphernalia associated with climbing and hill walking in Wales: full waterproofs, fleece, hat, gloves and of course some lunch.
