Grizzly bears are spreading out across Idaho. You can encounter grizzlies in many of the Northern Idaho mountain ranges and all along the Idaho/Montana border from I-15 (Monida Pass) to Yellowstone National Park. This area includes the Bitterroot, Beaverhead, Centennial and Henrys Lake mountain ranges. The bear population is also expanding its range into the Selway-Bitterroot Wilderness and the Frank Church River of No Return Wilderness. As part of the Greater Yellowstone ecosystem, the Henrys Lake Range and the Centennial Mountains are prime habitat for grizzly bears and bear encounters should be expected.
