Every April and May, Yellowstone wakes from its wintry slumber. Grizzlies emerge from hibernation, bison calves nicknamed "red dogs" take their first wobbly steps, and wolves hunt aggressively to feed growing litters. Spring floods the landscape with newborn wildlife and raw, unscripted moments — making it one of the most dramatic and rewarding times to experience the park.
Planning a Yellowstone & Grand Teton trip? Summer offers full access, spring and fall bring fewer crowds and incredible wildlife, and winter transforms the parks into a snow-covered wonderland. Whether you self-drive or go guided, the key is matching your season to what you want to experience most.
