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.

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 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.
