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-90 to Yellowstone National Park (including the Bitterroot, Beaverhead, Centennial, and Henrys Lake mountain ranges). The bear population is also expanding its range into the Selway Bitterroot and Frank Church River of No Return Wildernesses as well. As part of the Greater Yellowstone Ecosystem, the Henrys Lake Range and the Centennial Mountains are especially prime habitat for grizzly bears.
We highly recommend you visit the National Park Service’s Staying Safe Around Bears page before venturing into grizzly bear habitat.
Also, if your climb is in grizzly bear or black bear country, check with the appropriate U.S. Forest Service Ranger District to find out about current bear conditions.
