Summer: It's the height of the busy summer season and all-hands-on-deck as the epic Snowdon Race brings runners from all over the world to the mountain.

Big crowds bring problems for Rob and the Mountain Rescue Team and one of the glorious sights of the summer as farmers Jo and Fiona gather their sheep from the upper slopes.

The Spring sunshine brings new life and the crowds return to the busiest mountain in Britain. Railwayman Steff re-opens the summit cafe and also welcomes a ‘big spender' to the mountain as Shirley Bassey arrives to unveil a train carriage named in her honour.

The return of paying customers is good news for Alwena and her cafe 1,800ft up the mountain, but the busy paths to the summit spell trouble for Rob and his Mountain Rescue team.

From the National Park warden, a hill farming family and a mountain rescuer to a wild swimmer, the mountainside Cafe owner and those working on the small railway to the summit, this episode shows the many faces of this iconic British landmark.
