Elis and Miles plan to climb Snowdon, but first Elis has a treat for Miles - a trip on a new coaster ride through the forest near Betws-y-coed. Then Elis needs to shop for some suitable clothing before he can tackle England and Wales' tallest mountain, which severely tests the patience of Miles. On the day of the climb, Elis and Miles take the early morning staff train for a misty journey up the Snowdon Mountain Railway. The two comedians are left at Clogwyn station, about two-thirds of the way up, before walking the rest of the route. Shrouded in eerie mist they bravely push on to the summit, the tea bar and gift shop.
