The railway uses vintage steam locomotives that are over 100 years old.
The track gauge is 1 foot 10.75 inches, specifically designed to match the original slate quarry internal rail systems.
The line follows the path of the original Padarn Railway, which was one of the earliest public railways in the world.
Some of the engines currently in use were built specifically for the Dinorwic Quarry slate transport requirements.
The railway track skirts the edge of Llyn Padarn, a lake reaching depths of 94 feet.
The locomotives are maintained in a workshop that is accessible to visitors at the Gilfach Ddu station.
The Llanberis Lake Railway operates a narrow-gauge steam locomotive service along the northern shore of Llyn Padarn in Snowdonia National Park. The five-mile return journey departs from Gilfach Ddu within Padarn Country Park. The line utilizes historic steam engines that originally transported slate from the Dinorwic Quarry to the port of Y Felinheli. Passengers travel in open carriages, providing views of the lake and the surrounding slate mountains. The route terminates at Penllyn, allowing for short stops during the transit. The railway is situated on the site of the former quarry workshops, which now house the National Slate Museum. It remains one of the few functional heritage railways in the region reflecting the industrial history of the 19th-century Welsh slate industry.
The lakeside section near the midpoint of the route offers the best view of the steam engine reflected in the water.
Bring a windproof jacket, as the weather near the lake can change rapidly regardless of the season.
Combine your train ride with a visit to the adjacent National Slate Museum for a full day of industrial history.
Book tickets in advance during peak summer months to ensure a seat on the steam-hauled services.
