It was the raw wild beauty, mystical hot springs and rugged landscape which compelled Ulysses S. Grant to make Yellowstone the world’s first National Park in 1872. Luckily for us, the parks have been allowed to remain wild and for those who choose to stray from the crowded tourist pockets, relatively untouched. At nearly 2.2 million acres, there is an overwhelming amount to be seen here. Pro tip: Hit the major sights early before busses inundate the park. Spend the middle of the day on trails less frequented by tourists, and settle in at the end of the day roasting marshmallows around the fire pit.
