Wales's highest mountain is the only British peak outside Scotland with a rack railway to the summit — built in 1896 in the Swiss tradition — and its Welsh name, Yr Wyddfa, marks it as the legendary burial place of a giant slain by King Arthur.
About Snowdon
Snowdon's form was shaped by glaciation, its cwms carved by ice. The 1896 rack railway opened Swiss-style summit access; the mountain's Welsh mythology predates both, linking the summit to Arthurian legend through the giant Rhita Gawr's burial mound.
Overview Snowdon — Yr Wyddfa in Welsh — is the highest mountain in Wales at 1,085 metres and the Wales component of the British Three Peaks. The mountain sits at the center of Eryri (Snowdonia) National Park, a UNESCO-recognized landscape of glaciated valleys, lakes, and rugged peaks in northwest Wales. Snowdon is the most climbed mountain in Britain — approximately 500,000 people ascend annually — and the only British mountain outside Scotland with a rack railway running to the summit, providing access for those who don't walk.

The Story Behind It The mountain's Welsh name — Yr Wyddfa, meaning the tumulus or burial mound — reflects a mythological tradition that places the grave of a giant named Rhita Gawr at the summit, slain by King Arthur. The geological reality is less mythological but equally dramatic: Snowdon's current form was shaped by successive glaciations, most recently the last ice age that carved the cwms — steep-sided glacial cirques — visible on the mountain's north and east faces. The Snowdon Mountain Railway, opened in 1896, was built in the Swiss tradition of rack-and-pinion mountain railways and provides the only powered ascent in Britain to a mountain summit.
What You'll Experience Six established walking routes ascend the mountain from different directions, with varying levels of difficulty. The Pyg Track from Pen y Pass is the most direct and popular; the Watkin Path from the south is longer and less frequented; the Rhyd Ddu path on the west face is the most peaceful. The summit, on clear days, provides views over much of Wales, the Wicklow Mountains in Ireland, the Isle of Man, and the Lake District in England. The summit café — Hafod Eryri — is open when the railway runs and offers the peculiar experience of drinking coffee at 1,085 metres in northwest Wales. The railway runs from Llanberis; a return ticket covers the ascent and descent.
Getting There Llanberis, at the mountain's base, is served by buses from Bangor and Caernarfon. Bangor has mainline train connections to London Euston. The Pen y Pass car park requires advance booking in summer; shuttle buses from Llanberis replace private vehicles as the park manages congestion.

The Experience
Ascend by the Pyg Track from Pen y Pass for the most direct walking route, or take the 1896 rack railway from Llanberis, drink coffee at the summit café Hafod Eryri with views over Wales and Ireland, and choose a different descent route from the ascent for varied landscape.
Why It Matters
The highest mountain in Wales and the most climbed mountain in Britain outside Scotland — the centerpiece of Eryri National Park and the Wales component of the British Three Peaks.
Why Visit
The cwms on Snowdon's north face — steep-sided glacial cirques holding lakes at their base — are among the most dramatic glacial landscapes in Wales. The summit on a clear day is a genuine panorama; the rack railway is a working piece of Victorian mountain engineering.
Insider Tips
- 1
Pen y Pass car park requires advance booking in summer through the Snowdonia National Park website — book before departure.
- 2
The Pyg Track and Miners' Track from Pen y Pass create a natural circular route — ascend one, descend the other.
- 3
The summit can be in cloud while Llanberis is sunny — the railway operationally requires visibility at the summit, which is not guaranteed.
- 4
The Watkin Path from the south is longer but quieter and passes through Victorian slate quarry remains worth exploring.
