Moelwyn Mawr forms part of the Moelwynion. It has a high reservoir, Llyn Stwlan, which is part of the Ffestiniog Power Station pumped-storage hydroelectric power plant in Tanygrisiau.
In 1990, Moelwyn Mawr was designated a Site of Special Scientific Interest of national scientific importance. The glaciated landscape of the mountain provides fine examples of two specific Pleistocene features. On the north-east flank of the mountain is a terrain of patterned ground, consisting of small-scale vegetated stripes. On the west side, a debris tongue formed by a rock glacier extends into Cwm Croesor.
Moelwyn Mawr overlooks the Vale of Ffestiniog and affords spectacular views in all directions.
