Llanberis sits at the foot of Yr Wyddfa (Snowdon), Wales's highest peak, and is the most popular base for climbing it. The Llanberis Path is the longest but most gradual route to the summit — suited to anyone who is reasonably fit — and for those who prefer not to walk, the Snowdon Mountain Railway has been carrying visitors to the top since 1896.
The setting is genuinely beautiful: the village wraps around Llyn Padarn, a lake backed by the grey slate walls of Dinorwig quarry. The National Slate Museum, housed in the old quarry workshops, tells the story of the industry that once employed most of the valley and is free to enter. On the rocky knoll between the two lakes, Dolbadarn Castle is a striking medieval tower built by Llywelyn the Great, free to visit and worth climbing for the views. Just outside the village, Electric Mountain offers guided tours inside the Dinorwig pumped-storage power station, carved into the old quarry — one of Britain's most extraordinary engineering achievements.
After a day on the mountain, Pete's Eats is the classic walkers' cafe — enormous portions, long opening hours, and a community notice board of local routes and conditions.
