Running Wild with Bear Grylls - Season 5: Episode 4

Comedic actor Rob Riggle joins Bear Grylls on an adventure on Iceland’s Vatnajokull Glacier. Their journey begins with a helicopter ride over “the land of fire and ice,” aptly named for constant volcanic activity beneath the surface. Once dropped off, Bear and Rob must navigate a stretch of jagged ice fields, deep moulins and deep crevasses. Without food or supplies to make shelter, their mission is to find an airdropped emergency cache.
