Lying on the southern banks of Llyn Padarn, the village takes its name from Saint Peris, an early Welsh saint; population around 2,000. It is a base for ascents of Snowdon, the highest mountain in Wales and England.
The Llanberis Path is the most popular walking route to the summit, largely following the line of the Snowdon Mountain Railway. The Snowdon Mountain Railway was built in 1896 and is the only public rack and pinion railway in the UK. Steam hauled, single carriage trains (and now new diesel trains as well) have taken visitors to the summit for well over a century and 2009 saw the opening of the Hafod Eryri, the new building at the top of Snowdon.
The Llanberis Lake Railway is a narrow gauge steam railway which runs for 2.5 miles along the north bank of the lake starting from Gilfach Ddu station in the Padarn Country Park along the route of the Padarn Railway, which served the slate quarries in the area. The National Slate Museum is sited in the Victorian workshops built in the shadow of Elidir Mountain, site of the vast Dinorwig quarry which closed in 1969.
The workshops and buildings are designed as though quarrymen and engineers have just put down their tools and left the courtyard for home, while an array of talks and demonstrations including slate-splitting give a real insight into quarry life. Padarn Country Park is set in 800 acres of countryside, which includes Padarn Lake and the surrounding woodland.
Canoeing and sailing facilities are available on the lake and there are country trails and walks through the nature reserve and forest. Electric Mountain is the First Hydro Company's Visitor Centre; its split level layout contains a gift shop and cafe and is the starting point for the tour of Dinorwig Power Station.
From the centre, a bus will transport visitors to the Power Station itself, descending deep inside the mountain's labyrinth of dark and imposing tunnels, where visitors will experience one of man's greatest engineering achievements.
