Yr Wyddfa & Eryri (Snowdonia)
📍 Gwynedd, North Wales, United Kingdom
The rugged mountain heart of Wales — a national park of glacier-hewn peaks, glacial lakes and Welsh-speaking valleys crowned by Yr Wyddfa (Snowdon), the highest mountain in England and Wales.
What makes it marvelous
Eryri — known in English as Snowdonia — is a compact wilderness of ancient volcanic and sedimentary rock, folded, faulted and then carved by Ice Age glaciers into cirques, knife ridges and hanging valleys. At its centre stands Yr Wyddfa (Snowdon) at 1,085 m, the highest summit in England and Wales, ringed by classic glacial features: the deep bowl of Cwm Idwal, the arête of Crib Goch, and dark lakes cupped beneath the crags. The mountains hold rare arctic-alpine survivors such as the Snowdon lily, a plant left stranded here since the last ice age, while the surrounding slate country tells the industrial story that reshaped the region.
Why visit
Yr Wyddfa is one of Britain's great mountains — reachable on foot by a spread of famous paths, or by the rack-and-pinion Snowdon Mountain Railway for those who want the summit view without the climb. Beyond the honeypot peak lies a whole park of quieter ranges, adventure hubs, waterfalls and lakes, all of it strongly Welsh-speaking country.

What to know before you go
🗓️ Best time
May to September for the longest days and best chance of a clear summit; the mountain is busy in summer and serious in winter, when snow and ice demand full mountaineering skills.
🧭 Getting there & access
Llanberis, Pen-y-Pass and Betws-y-Coed are the main bases. The park lies within reach of the A55 North Wales coast road; Bangor is the nearest mainline rail hub, with local buses (the Sherpa'r Wyddfa network) serving the trailheads.
Good to know
- Pre-book parking at Pen-y-Pass — it fills before dawn in summer — or use the Sherpa bus.
- Crib Goch is an exposed grade-1 knife-edge scramble, not a walking route; avoid it in wind or wet.
- Carry map, compass and warm waterproofs; the summit is far colder and cloudier than the valley.

Eryri — Snowdonia to English speakers, and since 2022 officially known by its Welsh name — is the mountain heart of Wales: a national park of glacier-carved peaks, dark lakes and Welsh-speaking valleys. At its centre rises Yr Wyddfa, or Snowdon, at 1,085 metres the highest mountain in both England and Wales, and one of the most climbed summits in Britain.
The rock here is ancient — volcanic and sedimentary layers folded and faulted long ago, then sculpted by Ice Age glaciers into cirques, knife-edge ridges and hanging valleys. The results are on full display around Yr Wyddfa: the deep bowl of Cwm Idwal, the airy arête of Crib Goch, and lakes cupped beneath sheer crags. In a few high, cold corners the Snowdon lily still clings on, a fragile arctic-alpine plant marooned here since the ice retreated.
You can reach the summit on foot by a spread of storied paths, or ride the rack-and-pinion railway from Llanberis. Either way the reward on a clear day is a view that reaches across Wales to the sea — and, all around, a park of quieter ranges, waterfalls and slate-country history waiting beyond the crowds.
