Yellowstone National Park
Yellowstone National Park can be prohibitively crowded, but most visitors simply ride through the park and catch sight of the most popular attractions, leaving a majority of the land deliciously uncrowded. Walking along any trail, even a few steps from the main roads, will undoubtedly lead to some wildlife encounters, with foxes, birds, bears and bison on the snapshot menu. One of the most interesting animal inhabitants in Yellowstone is the American bison (also called buffalo). These 1-ton creatures thrive in the park, with over 4,000 roaming freely during the peak grazing season. Scouring Yellowstone's meadows and grasslands will certainly lead to some great bison pictures. Visitors can imagine what it must have been like when these impressive beasts dominated the prairies of the Midwest and Mountain West more than a century ago.
