Summit of Aran Fawddwy

Highlight • Summit

An often-ignored, almost secret mountain, Aran Fawddwy is the UK’s highest mountain south of Snowdon. Rising high above the shattered crags plummeting into Creiglyn Dyfi tarn, Aran Fawddwy forms a long, sweeping ridgeline with its outliers – and its summit is a fine place to gaze across the artistry of Snowdonia.

Arenig Fawr is one of my favourite mountains in Wales. Grand enough to be impressive and not anywhere close to being as busy as the more famous northern peaks. It has an imposing 854-metre (2,802 ft) summit well known for its ruggedness and remoteness. It has a rather wild feel to it at its trig-pointed top, where there is also a wind shelter. In addition, there is an impressive but sombre war memorial dedicated to the 8-man crew of a US B-17 bomber which crashed and perished on the summit in 1943 during night-flying exercises.

The best way to hike Arenig Fawr is the circular, 10-mile (16.1 km) route from the Arenig Quarry car park on the back road near Llyn Celyn. This walk will give you stunning views of the Snowdon range to the northwest. This hike also passes Llyn Arenig Fawr, where there is a small bothy, and gives you a great ridge walk to the summit.

Aran Benllyn

Highlight • Natural Monument

Aran Benllyn may be lower than its neighbour, Aran Fawddwy, but it is easily as characterful and features wide-ranging views across Northern Snowdonia.

It is often ascended along with its parent peak and the nature of its long linnear ridgeline makes circular routes difficult to create. This might have something to do with why the Arans are so much quieter than their height and scenic majesty would have you believe.

Rhinog Fawr Summit Cairn

Highlight • Natural Monument

This is the rough part of Snowdonia. Not ‘trolleys in the canal’ rough, but a craggy, vegetated, wild kind of rugged. Stick to the paths, such as the Roman Steps (actually a medieval packhorse route) for the easiest going, or head off the beaten track to tackle the heather and rocks for full-on adventure.

December 1, 2025, Arenig Fawr Summit & Flying Fortress Memorial

The memorial is right next to the summit cairn, and is suitably low key for such a location and what it commemorates.

A very fine mountain that benefits from being a bit off the beaten track, so you are unlikley to see many other people up here. The cliffs on the easten side areabout a thousand feet high.

October 10, 2025, Aran Benllyn

The northern end of the main Arans' ridge and a fine mountain in it's own right. It does tend to become an afterthought after it's bigger neighbour, but it is well worth the up and down walk along the ridge.

As the Arenig Fawr is an isolated peak the views in all directions are very good - including to the nearby Rhinogs.

A fine summit atop an isolated peak so there are wide views in all direction. Also a very fitting memorial.

Very fitting memorial at the summit of Arenig Fawr.

The Rhinogs are rightly recognised as being the roughest hills in Wales, so any ascent should bear that in mind. The easiest and clearest route is from the East, starting from the small car park at the end of the lane off the A470. This route is easy to follow and relatively easy to walk. The routes from the west include very difficult walking and few paths.

The battered trig point on Aran Fawddwy is built of blocks rather then being a concrete lump, and it's exposed and airy position does mean it is on the receiving end of a lot of weather.
