Llanberis (LLR) railway station is the southern terminus of the Llanberis Lake Railway (LLR), located in Llanberis, Gwynedd, Wales. The line and station primarily serve tourists and railway enthusiasts.
Most of the LLR was laid around 1970 on the trackbed of the closed and lifted Padarn Railway. The line opened between Gilfach Ddu (LLR) and Cei Llydan on 28 May 1971, being extended northwards to Penllyn (LLR) in 1972. For thirty years the new line's southern terminus was Gilfach Ddu (LLR), situated a short distance south of the site of the Padarn Railway's former workmen's station, also named Gilfach Ddu. In 2003 a wholly new extension was opened south westwards, with Llanberis (LLR) station as the line's new southern terminus.
