About Manod Mawr
Quarrying has shaped Manod Mawr more than any other force. This peak in the eastern Moelwynion of North Wales — a group sometimes grouped together as the Ffestiniog hills — has been worked extensively, and the disused Graig Ddu Quarry occupies the hollow at around the 600 m contour between the main summit and Manod Mawr North Top. At one stage there was concern that continued extraction might eat away the North Top altogether.
The Manod tunnels have an unusual wartime history: during the Second World War they served as a secret store for paintings evacuated from the National Gallery in London. Although the hills sit close to Snowdonia, the summit falls inside the national park's exclusion zone around Blaenau Ffestiniog, and the North Top lies only just outside the park boundary.

Finding the summit
this feature is 50m E of trig point base in shelter.
The recorded summit point is boulder with shelter. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Twelve highest shown, of 15 in the group.
Grouping is by prominence alone: a summit belongs to the nearest higher Marilyn it connects to without a deeper intervening col. Over a large massif that can gather hills no one would walk in a single day, and which few would describe as parts of the same mountain — it is a measure of independence, not a suggested route.
