14. Badlands National Park

South Dakota

Conveniently located off Interstate 90, you can either drive through Badlands National Park on the loop road in just a few hours or relax a bit and spend the night. During your trip through the park, you’re surrounded by beautiful rock formations with millions of years of history.

Stop and walk along Fossil Exhibit Trail’s boardwalk to understand the animals that used to roam here. Another spot not to be missed is the Roberts Prairie Dog Town where you’ll see hundreds of prairie dogs and hear them chattering away. Keep an eye out for bison; you’re sure to see a few during your drive. There are many viewpoints to explore, and as the Sun moves through the day, its color changes on the rock formations, which is why sunrise and sunset are brilliant times to experience the park.

The Lakota nation named the area “Badlands” and it can be unforgiving, so be prepared with proper sun protection and plenty of water when visiting in the summer.

15. Mount Rainier National Park

Washington

Mount Rainier National Park is known for its amazing hikes, gorgeous lakes and waterfalls, wildflower-filled slopes, and of course, views of the iconic Mount Rainier. The park’s namesake is an active volcano, although it hasn’t erupted since 1450. Located in the Paradise section of the park, the Skyline Trail is popular with visitors offering a little something for everyone — waterfalls, flowers, and plenty of breathtaking views. Avoid the crowds by visiting the more remote Carbon River area. It’s home to the only inland rainforest in the park.

Pro Tip: Know Before You Go

Many national park visitors visit just for a day, but you should try to spend the night. Many offer lodging in addition to camping and the parks are even more wonderful once the day-trippers leave. Also, don’t forget about the park system’s Junior Ranger program. In spite of the name, there isn’t an age limit to participate and it’s an interesting way to learn a lot about a park.
