Just east of Tower-Roosevelt, Lamar Valley, a must-see in Yellowstone, provides one of the most plentiful opportunities to catch a glimpse of Yellowstone’s exotic wildlife such as elk, bison, osprey, bald eagles, antelope, moose, black bears and grizzlies, as well as bears and wolves. Early morning and late evening are the times of day where you’re most likely to have the best luck to see epic wildlife in the park.
