In the last of the series, Snowdon gradually falls silent in the winter months and the residents around the highest peak in England and Wales have the mountain almost to themselves.
Mountain rescuer Rob chases the Autumn light for some spectacular early morning filming. Railwayman Steff shuts down the summit centre at Hafod Eryri as the season ends, while Alwena also calls temporary time on her Halfway Caf.
Wild swimmer Viv goes for a bracing winter plunge and Jo the mountain farmer finally sets foot on the summit of Snowdon for the first time!
The Mountain – Monday at 8.00pm on ITV.
