Snowdonia National Park, now officially called Eryri, covers a wild mountain region in North Wales. It is one of the great natural areas of the United Kingdom. It is home to Yr Wyddfa, or Snowdon, the highest mountain in Wales at 1,085 metres. Moreover, lakes, waterfalls, castles and slate villages complete the landscape. So, it is a paradise for hikers.
This guide covers the mountain, the villages, castles, walks and practical tips.


Climbing Snowdon
Six main paths lead to the summit. For example, the Llanberis Path is the longest but easiest. Meanwhile, the Pyg Track and the Miners’ Track start from Pen-y-Pass. Also, the Snowdon Mountain Railway climbs to the top from Llanberis in summer.

Lakes and Waterfalls
Llyn Idwal sits in a dramatic glacial bowl, reached by a short walk. Also, Llyn Gwynant is a peaceful lake in a green valley. In addition, Swallow Falls near Betws-y-Coed is a famous waterfall.

Villages of Snowdonia National Park
Betws-y-Coed is the main gateway, with stone houses, forests and outdoor shops. Meanwhile, Beddgelert is linked to the legend of Gelert, a faithful dog. Also, its riverside walks are lovely.


Castles Around Snowdonia National Park
Dolwyddelan Castle was built by the Welsh prince Llywelyn the Great in the 13th century. Just outside the park, moreover, Caernarfon Castle is part of a UNESCO World Heritage site. In fact, it is one of the most impressive castles in Britain.

Best Time to Visit Snowdonia National Park
From May to September, the weather is milder and the railway runs. In contrast, winter brings snow and ice on the summits. So, only experienced walkers should climb then.
Practical Tips
- Check the mountain forecast: Conditions change very quickly.
- Bring waterproofs: Rain is frequent all year.
- Park early or use buses: Pen-y-Pass parking must be booked in advance.
- Learn a few Welsh words: Welsh is widely spoken here.
Getting There
Trains run to Bangor and Betws-y-Coed, and Sherpa’r Wyddfa buses link the trailheads. For more ideas, see the official Eryri National Park website.
