7. The Black Hills & Badlands, South Dakota

For a classic American road trip that combines iconic monuments, stunning landscapes, and abundant wildlife, it’s hard to beat the Black Hills and Badlands of South Dakota. While the region is vast, a well-planned trip can be surprisingly affordable, especially for those who enjoy camping or staying in modest small-town motels.

When to Go & Weather

The best time to visit is from late May to September. Summer (June-August) has warm days and cool nights, with highs in the 70s and 80s°F (25-30°C), but it’s also the busiest season. For fewer crowds and slightly lower prices, aim for September after Labor Day. The weather is still beautiful, and the fall colors begin to emerge. Be prepared for rapidly changing weather, including afternoon thunderstorms in the summer. For official alerts, check with the National Weather Service.

Getting There & Around

Rapid City Regional Airport (RAP) is the primary airport for the region. A car is essential for exploring this area. The main attractions are spread out, and the scenic drives, like the Needles Highway and Iron Mountain Road in Custer State Park, are a highlight of the trip. Plan your driving routes in advance, as some roads are narrow, winding, and not suitable for large RVs.

Costs & Passes

A Custer State Park entrance pass is required and costs around $20 per vehicle for 7 days—an excellent value. Mount Rushmore National Memorial has no entrance fee, but there is a parking fee of about $10. Badlands National Park has a per-vehicle entrance fee (around $30), which is valid for 7 days. If you plan to visit multiple national parks in a year, the America the Beautiful Pass ($80) is a great investment. The National Park Service Senior Pass offers lifetime access for a one-time fee for U.S. citizens or permanent residents age 62 or over. Accommodation can be found in towns like Custer, Hill City, or Keystone for $130–$220 per night. Camping is a much more affordable option.

Actionable Tip

To see the impressive bison herds in Custer State Park, drive the 18-mile Wildlife Loop Road early in the morning or late in the afternoon when the animals are most active. This is a free activity once you’ve paid your park entrance fee.
