Friog (Welsh: Y Friog) is a small village in North Wales, near Fairbourne.
Its lake and beach are a tourist attraction to over 1,000 visitors a year.
Friog is notable for a rockfall-prone section of railway track, scene of two fatal accidents in 1883 and 1933 on the Cambrian Line. In both incidents, the only deaths were of the crew when the locomotives toppled over the edge of the cliffs after striking landslides with the coaches remaining on the track. In response, the Great Western Railway constructed a concrete avalanche shelter over the line in 1940.[1]
