Bear Island offers an unprecedented close-up look at one of most majestic creatures on the planet - the grizzly bear. For the first time ever, National Geographic's Crittercam® team deploys its groundbreaking camera technology to track one of North America's largest land predators. Crittercam is a revolutionary animal-borne research tool that records images, sound, and data from an animal's perspective.

InBear Island, bear biologist LaVern Beier of the Alaska Department of Fish and Game and the National Geographic Crittercam team join forces to vicariously walk with grizzlies into the deepest corners of their habitats.

One of the last grizzly strongholds, the dense rainforests of Chichagof Island in southeast Alaska hide more of these bears per square mile than any other place on Earth. But logging, road construction, and human development are changing the shape of the grizzlies' world. As the modern world closes in, the great bears' world is shrinking, and encounters between humans and bears are on the rise.
