Bear Grylls enters the heart of Dracula country; forest of Transylvania, where he encounters steep ravines, cavernous underground water systems, and comes face to face with a large adult brown bear.
Bear is a bit shaken by an encounter with a brown bear in the Carpathian Mountains. So he constructs an alarm system to warn him should a bear wander into his camp while he sleeps. After that even an underwater swim through a cave tunnel doesn't phase him.—David Foss
