Opened 1868: Passenger trains began serving Betws-y-Coed on April 6, 1868. The London & North Western Railway extended the Conwy Valley line (which had reached Llanrwst in 1863) to Betws-y-Coed, initially for freight in 1867. Slate Transport: The primary purpose of the Conwy Valley line was to transport dressed slate from the quarries in Blaenau Ffestiniog to Deganwy for export. A further extension to Blaenau Ffestiniog opened in 1879. Tourist Hub: The railway became the main way for tourists to reach Betws-y-Coed, and the station was designed with ample facilities to cope with the crowds. Local Builder: The station building itself is quite substantial for a country branch line and was constructed by local contractor Owen Gethin Jones, a renowned stonemason, carpenter, civil engineer, and poet. Decline and Revival: Like many branch lines, it saw a decline in the 20th century. However, its scenic route and importance for tourism have ensured its continued operation.

Llyn Crafnant is a lake that lies in a valley in Wales where the northern edge of the Gwydir Forest meets the lower slopes of the Carneddau mountains and, more specifically, the ridge of Cefn Cyfarwydd. The head of the valley offers a profile of crags which are silhouetted at sunset. The Forest Park guide (2002) states that "the (view along Llyn Crafnant) is one of the most breathtaking views in all Snowdonia" Crafnant takes its name from “craf”, an old Welsh word for garlic, and “nant”, a stream or valley. Many visitors walk there from the village or from the neighbouring lake of Llyn Geirionydd, which runs parallel to it, but a mile distant, the two being separated by Mynydd Deulyn – “mountain of the two lakes”. The lake can also be reached on foot from Capel Curig.
