UpToWhereWhat can you see from Snowdon (Yr Wyddfa)?
Edmund Hillary trained on its slopes before the first ascent of Everest.
From Snowdon (Yr Wyddfa), the terrain-limited line of sight reaches up to 232 km. The single farthest piece of visible terrain lies 232 km to the north (bearing 354°), at 843 m elevation. These results account for Earth's curvature and standard atmospheric refraction, computed from 30-meter resolution Copernicus GLO-30 elevation data across 2,076,191 terrain samples.

About Snowdon (Yr Wyddfa)
Snowdon, known in Welsh as Yr Wyddfa, is the highest peak in Wales at 1,085 metres and one of Britain's most climbed mountains, served by six marked paths and a rack-and-pinion railway. That railway opened in 1896 and remains the UK's only public rack railway, despite a derailment that killed a passenger on its opening day. In 1953, John Hunt's Everest team trained on Snowdon's slopes and tested oxygen equipment nearby before Hillary and Norgay's first ascent, and Welsh legend still holds that the summit cairn covers the grave of a giant.
Did you know?
- The Snowdon Mountain Railway's opening day in 1896 ended in disaster when a locomotive derailed and a passenger died jumping clear.
- Crib Goch, a knife-edge ridge scramble on Snowdon's flanks, is considered one of the most exposed and dangerous scrambling routes in Britain, drawing experienced hikers each year.
- The rare Snowdon lily grows only on a few cliff ledges near the summit — the only place in Britain where this Arctic-alpine flower is found.
- On a clear day the view stretches to Ireland, the Isle of Man, and England's Lake District.
- Snowdon's summit visitor centre, Hafod Eryri, sits at the highest point reachable by public transport in Wales.
