The Quarry Railway That Became a Pleasure Line
The Llanberis Lake Railway runs for five kilometres (2.5 miles) along the northern shore of Llyn Padarn, hauled by narrow-gauge steam locomotives that once worked in the vast Dinorwig slate quarry above the town. It is a gentler and more contemplative experience than the Snowdon Mountain Railway — a chance to sit back and watch the still waters of Llyn Padarn pass by with the mountains reflected in the lake, and Snowdon filling the horizon ahead.
The railway operates on the trackbed of a section of the old Padarn Railway, a 4-foot gauge horse-drawn tramway built in 1843 to carry slate from the Dinorwig quarry down to the port of Port Dinorwic (Y Felinheli) on the Menai Strait. This remarkable industrial railway hauled slate from one of the largest slate quarries in the world for over a century. When the quarry closed abruptly in 1969, the railway closed that October and the line was lifted between 1962 and 1963. Local enthusiasts envisioned restoring the line as a tourist railway using the surviving industrial locomotives from the quarry. In June 1970 the County Council purchased the trackbed and agreed to allow its use. The new railway was built to a slightly different gauge (1 ft 11½ inches, 597 mm), requiring all recovered rolling stock to be carefully regauged. Despite these challenges, the railway officially opened on 28 May 1971, with the first public trains running just weeks later on 19 July 1971. By the end of that first season, more than 30,000 passengers had been carried.
It is part of a great tradition of Welsh narrow-gauge railways — the famous “Great Little Trains of Wales” — and is one of the most scenically beautiful of them all. In 2003, the railway was extended to the town of Llanberis itself, with a new station close to the start of the Snowdon Mountain Railway, making it even more accessible to visitors.

The Journey
Trains depart from Gilfach Ddu station, situated next to the National Slate Museum and Padarn Country Park visitor centre, just a short walk from the centre of Llanberis. The line runs westward along the lake shore, passing through mixed woodland on the edge of the old quarry workings, with the waters of Llyn Padarn visible through the trees and Snowdon rising in the distance.
The intermediate halt at Cei Llydan is a popular stopping point. Passengers can alight here to enjoy one of the finest viewpoints in the park: a wide grassy bank beside the lake with unobstructed views across the water to Dolbadarn Castle and the mountains beyond. It is an ideal picnic spot and a favourite with photographers.
The line terminates at Pen Llyn station at the western end of the lake, where trains run round before the return journey. The full return trip takes approximately 40 minutes. Passengers can alight at Cei Llydan, explore the parkland, and catch a later train back, making the railway a pleasant way to spend an hour or two in the park.
The Locomotives
The railway’s locomotives are small narrow-gauge steam engines built for industrial quarry work, mainly in the early 20th century. They worked in the Dinorwig quarry hauling slate wagons on the internal narrow-gauge network and are now carefully maintained in running order by the railway’s volunteers and staff.
The flagship is Dolbadarn, a 0-4-0 saddle tank built by Hunslet of Leeds in 1922 and named after the nearby castle. Elidir (originally named Enid, then Red Damsel, before its present name) was built in 1889 and is one of the oldest working engines on the line. Thomas Bach, built in 1904, is another Hunslet product. All three are 0-4-0 saddle tanks — compact, powerful engines ideally suited to mountain work and tight curves. Watching these compact, purposeful engines working a passenger train along a lakeside track — doing something quite different from the hard industrial labour they were built for — is one of the quiet pleasures of the railway.
Several diesel locomotives are also maintained and available for days when steam is not available or undergoing maintenance, but steam haulage is the norm during the main operating season. The railway operates one of the most impressive collections of working industrial locomotives anywhere in the UK, all carefully restored and maintained to meticulous standards.
Padarn Country Park
The railway runs through Padarn Country Park, an 800-acre park on the shores of Llyn Padarn created on former quarry land. The park contains the National Slate Museum, woodland walking trails, picnic areas, a visitor centre, and direct access to the lake for water activities.
Llyn Padarn is one of Snowdonia’s cleanest lakes and is popular for open-water swimming, kayaking, stand-up paddleboarding, and fishing. The lake contains the rare Arctic char — a relic species from the last Ice Age that survived in these cold mountain waters when the glaciers retreated. Fishing permits are required and available from the park.
A lakeside cycle path follows the northern shore through the park, forming part of the Lôn Las Ogwen route, and connects to the wider Snowdonia cycling network. The path is also a pleasant flat walking route for those who prefer to travel on foot alongside the railway.

Is the railway accessible for people with mobility difficulties?
Yes. Gilfach Ddu station has accessible facilities. Trains accommodate wheelchair users with staff assistance (advance notice appreciated). Level platform boarding makes boarding easier. Facilities at Padarn Country Park visitor centre are also accessible.
Can children ride the Lake Railway?
Yes. Children of all ages travel safely. The journey is particularly popular with families — it's gentler and slower than the Snowdon Mountain Railway. Special children's fares apply. The railway is not a thrill ride, making it suitable for very young children and elderly passengers.
What if I want to combine the railway with other activities?
The railway is perfectly positioned for combining with other activities: visit the National Slate Museum (free entry, 1-2 hours), explore Padarn Country Park walking trails, have a picnic at Cei Llydan, or kayak/paddleboard on Llyn Padarn. A full day can easily be planned around the railway.
Why is this the better choice over the Snowdon Mountain Railway?
Both railways are excellent but offer different experiences. The Lake Railway is gentler, shorter, and more relaxing — ideal for families with very young children, those who want a shorter journey, or visitors preferring scenic lakeside views. The Snowdon Railway reaches the summit for mountain views. Choose based on your interests and energy levels.
