Lamar Valley hiking, Yellowstone National Park, WY
Grizzly bears, wolves, pronghorn, elk, and bison all cluster in the Lamar Valley, making this one of the world’s great wildlife-watching regions. Dawn is the best time to spot wolves, which are nocturnal and generally feed in the mornings, so start your wolf-vigil a half-hour before sunrise. Other critters can be spotted in the late afternoon and evening. Take a quiet hike on the Lamar River Trail, where the open grassland makes it easy to watch wildlife from a distance. It’s 7 miles round-trip to the backcountry campsites at Cache Creek, another wildlife hot spot, but you can reverse course anytime along the route.
