Bear Grylls helps Jonathan Ross to discover his inner Tarzan on a once-in-a-lifetime expedition to the magnificent rainforests on the volcanic island of La Palma, one of the least-known of the Canaries.
Bear challenges novice Jonathan with a series of exhilarating adventures during an intense two-day trip, including trekking through dense jungle with machetes, SAS-style fast-roping from a helicopter, a walk down an active volcano and sleeping in a cave in a steep cliff face.
Bear and Jonathan have to fend for themselves, including preparing wild animals for food.
