Moelwyn Mawr, Protected mountain summit in Snowdonia, Wales.
Moelwyn Mawr is a mountain in Gwynedd, Wales, standing 770 meters high with steep slopes and exposed rock faces. The north side features particularly dramatic cliff formations, while grassland and low plants cover much of the surrounding terrain.
The mountain was historically significant for slate extraction, with multiple quarries established on its slopes including Croesor and Rhosydd operations. These quarries shaped the local landscape and economy during the height of the Welsh slate industry.
The mountain forms part of the Moelwynion range, which has become a reference point for Welsh mountaineering and outdoor recreation activities.
You can approach the summit from various directions, but the main routes require mountain gear and good navigation skills due to exposed terrain. Weather changes quickly at this elevation, so waterproof clothing and layers are essential.
The northeastern slope displays distinctive striped ground patterns with low vegetation, a rare geological feature formed by specific soil processes. These formations occur only under particular conditions and create an unusual visual pattern on the mountain face.
