There is no better way to explore Yellowstone National Park than by foot. Yellowstone's most amazing features, from the Upper Geyser Basin to Old Faithful, are easily accessed well-designed boardwalks. The geothermal features are a feast for the senses, from the scent of steamy sulfur to the visually stunning power of Old Faithful's timely eruptions. Besides the must-see collection of thermal destinations, there is an entire backcountry to be explored. Here, deep forests spread out over the land, ending at high peaks that tower over a magnificent wilderness. Wildlife thrives in the park, from wolves and bears to pelicans and bison. The miles you travel on foot in Yellowstone will create lasting memories unlike anywhere else in the world.
