Llanberis, Heart of Snowdonia
Llanberis sits at the foot of Snowdon in the heart of Snowdonia National Park, cradled between the twin lakes of Llyn Padarn and Llyn Peris. It is one of the most visited destinations in Wales and, for many, the starting point for the greatest adventure North Wales has to offer: reaching the summit of Snowdon, the highest mountain in England and Wales at 1,085 metres.
It welcomes everyone from families looking for gentle lake walks to experienced mountaineers tackling world-class climbing routes on the surrounding crags.

A Town Shaped by the Mountains
The town has been shaped by the mountains around it. For over 150 years the vast Dinorwig slate quarry employed thousands of men who carved dramatic terraces into the hillside above Llanberis, extracting over 100,000 tons of slate annually at its peak and exporting Welsh slate across the British Empire to roof London’s terraces and line Manchester’s mills. Today, that legacy is preserved in the National Slate Museum (closed for redevelopment at the moment), one of Wales’s finest free museums featuring the magnificent De Winton waterwheel and authentic workers’ cottages. The quarry lakes are now home to one of the most powerful hydroelectric power stations in the world, hidden entirely within the mountain and capable of generating 1,728 megawatts within 16 seconds, a feat of modern engineering that sits quietly alongside the medieval history of Dolbadarn Castle and the natural grandeur of Llanberis Pass.
Whether you are here to conquer Snowdon on foot (choosing from six established routes with varying difficulty), travel to the summit by Victorian rack-and-pinion railway (Britain’s only public mountain railway), ride steam trains along Llyn Padarn, rock climb on world-famous crags, explore ancient medieval castles, mountain bike through the pass, fish or kayak on glacial lakes, or simply breathe in the mountain air and walk the woodland trails, Llanberis offers an extraordinary depth of things to do across all seasons.
Snowdon, 1,085 Metres
At 1,085 metres (3,560 feet), Snowdon (Yr Wyddfa in Welsh) is the highest mountain in England and Wales, and one of the most climbed peaks in the world. Over 500,000 visitors and climbers reach the summit annually. Geologically significant as the centre of a volcanic range formed in the Ordovician period, Snowdon’s distinctive peaks and ridges were carved by glaciation during the Ice Ages, creating the landscape you see today. From Llanberis, walkers can take the classic Llanberis Path, a steady 14-kilometre round trip that follows the route of the mountain railway all the way to Hafod Eryri, the striking visitor centre at the summit.
On a clear day the view from the top stretches to Ireland, the Isle of Man, and the mountains of the Lake District, a 360-degree panorama that makes every step of the climb worthwhile. The summit can be reached via six different established paths. The Llanberis Path is the longest but the most gradual, suitable for families and those building endurance. The Pyg Track and Miners’ Track from Pen-y-Pass are steeper and more dramatic, offering scenic variety and fewer crowds than the Llanberis Path. The Watkin Path from Nantgwynant offers the greatest ascent of all. The Snowdon Ranger Path from Llyn Cwellyn and the Rhyd Ddu Path are quieter and good for avoiding summer crowds. The famous Snowdon Horseshoe, over the knife-edge of Crib Goch, is a serious scramble for experienced mountaineers only.
For those who would rather let the train do the work, Snowdon Mountain Railway has been carrying passengers to the summit since 1896, well over a century of mountain travel. It is Britain’s only public rack-and-pinion railway, and the journey to Hafod Eryri, with its panoramic windows and glass-roofed café, is one of the great railway experiences in Britain. The railway climbs 7.5 kilometres through changing landscapes in about an hour, and runs from late March to late October.
Whatever your approach, a good pair of boots, warm layers, and an eye on the weather forecast are essential. Snowdon’s summit is frequently in cloud, and conditions can change rapidly at any time of year. The mountain demands respect, but the rewards (physical achievement, stunning views, and the sense of standing atop England and Wales) make it unforgettable.

Industry in the Mountains
National Slate Museum
The National Slate Museum sits on the site of the former Dinorwig quarry workshops. It is free to enter, but is closed at the moment for a major redevelopment. At its heart is the De Winton waterwheel, built in 1870 by craftsmen from Caernarfon: at 15.4 metres in diameter it is the largest surviving waterwheel on mainland Britain. Powered by water channelled from the slopes of Snowdon, the wheel once drove the workshop machinery that kept the quarry running.
The museum preserves the original quarry workshops, engine rooms, and slate-cutting sheds largely as they were left in 1969 when the quarry finally closed. Skilled craftsmen demonstrate traditional slate-working techniques, and a Victorian terrace of quarrymen’s cottages has been restored to show domestic life across four different eras.
Electric Mountain
Beneath the waters of Llyn Peris, hidden inside the hollowed-out mountain of Elidir Fawr, lies one of the great engineering wonders of Wales. Dinorwig Power Station is a pumped-storage hydroelectric facility capable of generating 1,728 megawatts within 16 seconds, faster than any other power station in the world. Its main turbine chamber, 51 metres high and 180 metres long, is said to be the largest man-made underground cavern in Europe. The Electric Mountain visitor centre in Llanberis, which used to run tours inside the mountain, closed in 2018 and the underground tours have not restarted, but the scale of the scheme is easy to appreciate from the shores of Llyn Peris.
Llanberis Lake Railway & Padarn Country Park
Running along the northern shore of Llyn Padarn, the Llanberis Lake Railway uses narrow-gauge steam locomotives that once hauled slate wagons in the quarry. In 2026 a short shuttle runs while cable work takes place; on the full line, the 40-minute return journey follows the lake shore through the parkland of Padarn Country Park, with an optional stop at Cei Llydan to enjoy spectacular views across the water towards Snowdon.
Padarn Country Park itself covers 800 acres of former industrial landscape now reclaimed by nature. Woodland trails wind past the ruins of quarry buildings, and the lake is popular for kayaking, swimming, and fishing. The park connects directly to the National Slate Museum and is the starting point for several waymarked walks and traffic-free cycle paths.
Dolbadarn Castle & Llanberis Pass
Standing on a rocky promontory between Llyn Padarn and Llyn Peris, Dolbadarn Castle was built in the early 13th century by Llywelyn the Great, Prince of Gwynedd. Its 12-metre circular tower is one of the best-preserved medieval round towers in Wales and a defining feature of the Llanberis skyline. The castle is managed by Cadw and is free to visit; from its tower the views across both lakes towards the mountains are superb.
Three kilometres south-east of Llanberis, the Llanberis Pass cuts through the mountains in a dramatic glacial trough. The A4086 passes beneath the sheer faces of Crib Goch and the Glyderau, one of the most famous mountain routes in Britain. The Pass is world-renowned among rock climbers, with dozens of classic routes on the crags above the road. Even for those with no intention of climbing, the drive or cycle through the Pass is an unforgettable experience.
Llanberis Events
The Snowdon Race (July) is one of the most famous fell races in the world. Competitors run from Llanberis High Street to the summit of Snowdon and back, a 15-kilometre course with 1,000 metres of ascent, and the best runners complete it in well under two hours. Thousands of spectators line the route.
The Snowdonia Marathon (October) starts and finishes in Llanberis, circumnavigating the Snowdon massif on a 26-mile course that rises to 362 metres at Pen-y-Pass. It regularly sells out months in advance and has gained a reputation as one of the most scenic marathon courses in Britain.
The Llanberis Carnival (July) has been a fixture in the town for generations. The carnival parade makes its way down the High Street past the hotels and into the park, and the event is a genuine community celebration with rides, music, and entertainment for all ages.
Eating & Drinking
Llanberis has a well-earned reputation among walkers and climbers for good, hearty food. Pete’s Eats on the High Street was for decades a Snowdonia institution, famous for enormous breakfasts that fuelled generations of summit attempts. It has since been refitted in a more modern café-bistro style, but it remains a handy stop on the High Street.
For something more leisurely, the Heights Hotel bar has long been the social hub of Llanberis, serving food alongside an excellent range of Welsh ales. The Royal Victoria Hotel at the lakeside offers more formal dining with views across Llyn Padarn to the mountains.
Down at Padarn Country Park, the Lake Railway has a café at its main station, and there are picnic spots all along the lakeshore.
