Bwlch Mawr, Mountain summit in Llŷn Peninsula, Wales.
Located at the northeastern edge of the Llŷn Peninsula, Bwlch Mawr rises to an elevation of 510 meters with a prominent trig point at its peak.
The Ordnance Survey established a triangulation station at Bwlch Mawr to measure and map the geographic features of North Wales during the national mapping project.
The Welsh name Bwlch Mawr translates to 'big pass' in English, reflecting the traditional Welsh practice of naming geographical features based on their physical characteristics.
Visitors can access the summit through a public footpath that crosses the southern slopes, while a bridleway extends southward from the village of Clynnog-fawr.
The summit contains an igneous intrusion dating back to the Palaeozoic era, forming part of a distinct geological formation across the Llŷn region.
