Arenig Fawr rises to 654 metres (2,802 feet) At the summit of the mountain stands a trig point and a memorial to the American air crew of Flying Fortress bomber which in 1943 crashed on Arenig Fawr, the crew of eight all lost their lives.

The Arenigs consist of three main summits Arenig Fawr, Arenig Fach (689 metres) and Moel Lyfnant (751 metres). The views from the summit of Arenig Fawr are spectacular and include most mountain summits in Snowdonia.
