Garnedd Ugain, Mountain summit in Snowdonia National Park, United Kingdom
Garnedd Ugain is a mountain summit in Snowdonia, Gwynedd, and the second-highest point in Wales at 1,065 meters (3,494 feet). It sits close to Snowdon and is linked to the surrounding ridges by narrow rocky connections within the same massif.
The Welsh name translates roughly as 'Cairn of the Twenty' and may refer to a Roman legion unit once stationed at the nearby fort of Caernarfon. The exact origin of the name remains uncertain and is still debated.
The peak is part of the Welsh 3000s, a challenge where walkers attempt to climb all Welsh summits above 3,000 feet in a single day. It sits along the route and is often crossed without a long stop, as the goal is the full traverse.
The summit is most often reached via the Snowdon Horseshoe route from Pen-y-Pass, which involves narrow ridges and rocky sections. In winter, ice and snow can make the crossing much harder, so experience on mountain terrain is worth having before attempting it.
On the northeastern side, a steep rocky spur called Clogwyn y Person drops sharply into the rocky bowl of Cwm Glas below. This slope is used by experienced climbers as an alternative line of ascent and is known for being technically demanding.
