2. Yellowstone National Park
Wyoming, Montana, Idaho
Old Faithful and Yellowstone National Park are practically synonymous, but America’s oldest national park is actually home to a staggering 500-plus geysers; many of which can be found around the Grand Loop Road. The southern portion of the road is also where you’ll find the colorful Grand Prismatic Spring, a must-stop for most visitors. The Yellowstone River is responsible for another dramatic experience — the Grand Canyon of Yellowstone and its Upper and Lower Falls. Finally, listen for howling wolves in the Lamar Valley. It offers the best wildlife viewing with herds of bison, grizzly bears, and adorable pronghorn, as well as wolves in the northwestern corner of the park.
3. Grand Canyon National Park
Arizona
The second most visited national park in the U.S., most visitors only see Grand Canyon National Park during a day trip. Instead, spend the night along the rim for a completely different experience. The changing colors of the canyon during sunrise and sunset will take your breath away. Then, the darkest of dark skies fills with stars to the delight of every junior astronomer. During the day, experience one of the park’s iconic mule rides, raft the Colorado River, hike into the canyon, or simply drive along the South Rim stopping at the lookouts along the way. While the South Rim is always open to visitors, the North Rim is planned to open on June 2.
