October 10, 2025, Aran Fawddwy Summit

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 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.

Waterfall on the river Gain, known as "Pistyll Gain". Very beautiful to see, even from a distance. The River Gain is a major tributary of the River Mawddach.

September 6, 2023, Aran Fawddwy Summit

The rocky and remote summit of Aran Fawddwy stands at 905 m. It's the only peak in Wales outside the northern Snowdonia range over 900 m. It's a tough run to the summit where ever you start from but the views are great and the descent via Hengwm is awesome!
