Yellowstone
Yellowstone was part of ☞ Grand Teton-Yellowstone-Bighorn Mountains-Black Hills-Badlands trip in 2013. We moved around a lot driving from destination to destination and then walking on local trails, such as Lone Star Geyser trail. We liked our only longer/all-day hike around Grand Canyon of the Yellowstone a lot.
