Bear Grylls is dropped into the Costa Rican rainforest; then demonstrates how to stay alive on the icy landscapes of the French Alps; spends the night in the steamy swamps of the Florida Everglades; builds a raft from bamboo and hibiscus bark on an uninhabited Polynesian island; and tries his hand at capturing a wild horse using a lasso made from willow branches in the Sierra Nevada mountains of California.
In the first episode, Bear Grylls touches down on the boiling sands of the North African Sahara Desert, where the daytime temperatures rise to 54C and the sand is almost too hot to touch. As the series continues, Bear faces waterfalls and mudslides in the deadly jungles of Panama; parachutes into the Patagonia ice field; takes on Namibia's Skeleton Coast, a 900-mile stretch of arid desert; and ventures into the landlocked country of Zambia in Southern Africa, where crocodiles, hippos and a herd of elephants are just some of the dangers in the area.
The series begins with Bear Grylls demonstrating his survival skills in Belize, home of the British Army's jungle warfare training programme. As events unfold, Bear enters the Carpathian Mountains of Transylvania; heads into the wilds of South Dakota; and fights his way across frozen glacial wastelands and treacherous white water in Yukon, one of the remotest, coldest places in North America.
In the fourth series Bear Grylls is left on the Panamanian coast, where he demonstrates how to harvest fresh water and make a raft, and shows how to survive a storm. Bear uses an ancient tribal technique in China to catch bats for food; jumps on a moving train in the Rockies; and tries to escape from a live volcano in Guatemala.
The series begins with Bear Grylls wading across a shark-infested tidal channel in Papua New Guinea. As the series continues, Bear demonstrates how to survive the sweltering landscape in Australia's Northern Territory; lands in the snow-capped Caucasus Mountains of the Georgian Republic; and takes two fans of the show into the Canadian wilderness, where they face their fears head on.
