This natural wonderland is home to so many national treasures. Devil’s Tower National Monument is located in Wyoming and attracts thousands of visitors each year to gawk at the striking landscape and rock climb. Home to Yellowstone National Park, the very first national park in the US, these hydrothermal features native to Wyoming have been studied by ecologists for decades. Just south of Yellowstone lies Grand Teton National Park, a striking mountain range that brings in backpackers and birdwatchers from all over the world.
