Llanberis sits at the foot of Snowdon on the shores of Llyn Padarn, a town shaped entirely by slate. The quarry workings that dominate the hillside above it were once the largest slate quarries in the world, employing thousands of men and roofing houses from London to New York. The quarries closed but Llanberis has reinvented itself as a walking and tourism base, retaining a working-town character that makes it more interesting than a purpose-built resort. Drive time from Betws-y-Coed is about 25 minutes via the A5 west and A4086 north through the spectacular Llanberis Pass.
The most extraordinary attraction in Llanberis is invisible from the road. The Dinorwig pumped-storage power station is built entirely inside Elidir Fawr, the mountain above Llyn Peris — an underground cavern system housing turbines capable of generating 1,800 megawatts within 16 seconds, making it the fastest-response large power station in the world. Electric Mountain is the visitor centre and runs guided tours deep into the mountain through a network of tunnels to the main turbine hall, a space so large it has its own weather. The engineering achievement — excavating 16 million tonnes of rock from inside a mountain — is genuinely astounding. Tours run throughout the day; advance booking recommended as spaces are limited.
Set within the original Dinorwig quarry workshops, the National Slate Museum is one of the best free attractions in North Wales. The Victorian machinery — the largest water wheel on the British mainland, the workshop lathes, the blacksmith’s forge — is still operational, with demonstrations running daily. Rows of quarrymen’s cottages have been recreated to show how families lived during the quarrying era. The museum tells the human story of the slate communities alongside the industrial one. Free entry; allow a minimum of two hours.
A short walk from the village centre, Dolbadarn Castle is a 13th-century Welsh tower fortress that overlooks Llyn Padarn with quiet authority. The round tower is substantially intact and can be climbed for views along the lake. Owain Goch, brother of Llywelyn ap Gruffudd, was imprisoned here for over 20 years. The castle is free to visit, managed by Cadw, and the walk to it from the town takes about ten minutes.
Llyn Padarn, at the foot of the town, is one of the most attractive lakes in Snowdonia and a centre for water sports. Paddleboarding and kayaking are available from operators on the lakeshore. The lake is also one of the few remaining habitats of the Arctic char, a glacial relic fish that has been isolated in Padarn since the last ice age. A lakeside walk circles the water in about two hours and passes the slate museum and castle on its circuit.
Llanberis has a good selection of cafes and pubs suited to a day that starts or ends on Snowdon. The village is genuinely accustomed to hungry walkers arriving at all hours and most cafes serve food throughout the day.

The Snowdon Mountain Railway departs from Llanberis and is the most popular way to reach the summit without walking. Steam and diesel trains climb to the summit in about an hour; book well ahead in summer at snowdonrailway.co.uk. The Llanberis Path is also the most gradual walking route to the summit and starts from the town centre. A full Llanberis day — Electric Mountain in the morning, Snowdon Mountain Railway in the afternoon, dinner in the village — is a satisfying and very full itinerary.
