(a) From Lliwbran.—The rocks rising from Lliwbran are columnar in structure, and by the time a generation of climbers have torn away the grass from the holds they will show up plenty of neat little problems from 50 to 100 ft. high.

Looking up from the lake the crag, which is a high dependence of Aran Benllyn, shows on the right an almost unrelieved slabbiness at an easy angle, which gives good practice in small footholds. Up to the centre of the crag is a steep grass gully, in a line with a large boulder down near the lake, with an overhanging wall that blocks the direct ascent of the gully, and with a fine clean-cut buttress on the left. We may creep up the corner of the wall on the left, or circumvent it by traversing round to the right.

The route to the ridge from the big boulder is easiest up an oblique gully just invisible from it. Between our crag and the summit of the Benllyn is an easy walk due east down to the green shoulder south of Lliwbran, that takes us quickly by Nant y Barcud and Cwm Croes to the Twrch valley and the main road. This descent to Llannwchllyn, though not direct, recommends itself in wet or misty weather, and is in any case worth taking as a variant. Aran Benllyn itself offers nothing on its broken escarpments; though the face shows up rather well in profile from a distance, the climber need scarcely use his hands in zigzagging up the face to the cairn. The view from the summit justifies our traversing the peak on the way to Aran Fawddwy. It includes the length of Bala lake and a goodly extent of Llyn Fyrnwy, and the outline of Aran Fawddwy shows up magnificently.

Passing along the ridge to the south of Benllyn we keep up at a high level for the whole distance of 1½ mile to Aran Fawddwy, the greatest depression being less than 250 ft. below Benllyn. If we bear to the left, just dipping below the ridge, we pass along the foot of an overhanging mass of rock of considerable length that is undercut in a remarkable fashion. There are many places along it where one may shelter comfortably in bad weather. It is difficult to climb up the rock direct, but towards its south extremity we may work up into a small cave and climb out by the left on to the ridge again.

Five minutes then bring us to a fine cairn that marks an easy descent to Craiglyn Dyfi, the source of the Dyfi river, with a good view of the best rocks on Aran Fawddwy. The final ascent of this peak begins after a few feet of descent to a wall that crosses the ridge at its lowest.

(b) On Craiglyn Dyfi.—A small terrace at about the level of the wall just referred to leads round the rocks to the left into a large scree gully, which offers good sport in snowy weather. Half-way along this terrace is a 'problem' of unusual severity—a narrow crack in an overhanging face, with very scanty hand-holds where the crack closes, some 20 ft. up the face. The pleasantest bit of scrambling is on to the summit of Aran Fawddwy from the lake, by the arête that is seen in outline from the large cairn on the ridge, from which point the two vertical portions of the arête are well marked. It can be reached easily from the lake, or we may descend from the cairn for some 600 ft., and then traverse across to the south till a small gully is passed that shows a cave pitch at its lower extremity. The rock arête forms the south side of this gully and runs up for 400 ft. It reminds us of the easy climb up Tryfaen from the Glyder side, though in one or two places we have difficulties here, whereas there are none on the Tryfaen scramble.

It begins below the level of the cave, and after passing over rough rocks at an easy angle we come to a fine wall with a wide crack up it on the left. A huge splintered block is fixed in the lower part of the crack, and we may surmount the block and just squeeze in, passing out on to the roof. There are one or two variations possible here. In fact, instead of starting on the arête we might pass up the gully to the cave. It has mossy walls and a dripping interior. It is marked by a small pile of stones on the right and a well-bleached sheep's skeleton in the gully just above. The pitch may be taken on the left by steep wet grass, which is unpleasant, or we can attack it direct. We go well inside, and with back to the right we find good holds on the left, thus working up until the roof itself offers hold for both hands. From here it is best to pass on to the arête a few feet below the crack above described.

The way is then easy, but interesting, and leads to a straight-up crack in a wall in front of us that has to be negotiated. It looks severe, but the surface of the rock is so rough that no real trouble is experienced with it. The crack is much more formidable to descend. Shortly after this we find ourselves out on the open face again, the gully on the left having disappeared, and only a few crags above us marking the summit of the mountain. Striking directly upwards we reach the top in a quarter of an hour, the last 25 ft. being, if we choose, by way of a chimney, that begins with some difficulty and lands us just to the left of the large cairn that marks the highest point.

(c) By Llaithnant.—Passing due south of the Aran Fawddwy cairn, along the route to Dinas, we see a fine rock in front between us and the near end of the Dyrysgol ridge, forming the head of Llaithnant. It is marked by an overhanging rock half-way down the left-hand ridge. A steep and wet scree gully leads down to the valley, and we may go part of the way down until we are about 100 ft. below the overhanging block.

Here we can strike across to the arête, and keeping close to the gully on our right have 250 ft. of fairly good scrambling. We skirt close under the big boulder, and passing to the right of it (a traverse can also be managed on the left, lower down) clamber over rather loose rock to the grass terrace above the pitch. Then good rock follows, and bearing towards the right we come in sight of a square-walled chimney overlooking the main gully, marked by small cairns at top and bottom. Its holds are all on the left, so we back up on the right and find ourselves close to the main ridge again. Another chimney still further to the right might be taken, but it is always very wet; the two pitches in it are both very small, and it is only interesting when ice is about.
