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

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.

The loop from Llandrillo going anticlockwise is very steady and pleasant. But be prepared for substantial bog trotting in the central part of the valley passing the area marked as Gwern Wynodl. Even with newish goretex boots, we came away with wet feet. Good boots and gaiters, or wellies for that section highly recommended. Return section (first section if doing it clockwise) is also pretty boggy in parts. It also seemed like a bit more of a slog doing it clockwise.

Camera does not do the extent of the view justice. It is simply stunning.
