Badlands, Black Hills, and Monumental Roads. 4 routes through alien landscapes, monument-studded mountains, and open prairie.
South Dakota delivers some of the most visually dramatic road trip scenery in America. The Badlands are an alien landscape of eroded buttes, pinnacles, and spires that change color with every passing cloud. The Black Hills are an island of forested mountains rising from the Great Plains, home to Mount Rushmore, Crazy Horse Memorial, and Custer State Park's roaming bison herds. The contrast between stark prairie and rugged mountains within a single day's drive is unlike anything else in the country.
What makes South Dakota exceptional for road trips is the concentration of top-tier sites in a relatively compact area. Mount Rushmore, Crazy Horse Memorial, Badlands National Park, Wind Cave National Park, Custer State Park, Jewel Cave National Monument, and the Needles Highway are all within a 90-minute drive of Rapid City. You could spend a week exploring and still not see everything.
The value proposition is strong too. South Dakota has no state income tax, which translates to lower prices across the board. Campgrounds in Custer State Park run $20-30/night with bison literally walking through your campsite. Where else can you get that?
From the Badlands' alien spires to Rushmore's granite faces.
This is the definitive South Dakota road trip, combining the state's greatest hits into one epic loop. Start in Rapid City, drive through Badlands National Park's otherworldly landscape (the Loop Road is 31 miles of jaw-dropping scenery), then head into the Black Hills for Mount Rushmore, Crazy Horse Memorial, Wind Cave National Park, Custer State Park (where herds of 1,400 bison roam free), and the Needles Highway - one of the most dramatic mountain roads in America.
These two roads - SD-87 (Needles Highway) and US-16A (Iron Mountain Road) - are engineering marvels built in the 1930s specifically for scenic driving. Needles Highway threads between granite spires through tunnels barely wider than a car. Iron Mountain Road features pigtail bridges (spiral bridges that gain elevation by looping over themselves) and tunnels perfectly framed to reveal Mount Rushmore in the distance. Together, they're the most thrilling 50 miles of road in the Great Plains.
Custer State Park's 18-mile Wildlife Loop Road is the best drive-through wildlife viewing in the lower 48 outside of Yellowstone. A herd of roughly 1,400 bison freely roams the park, and you'll encounter them on the road - sometimes blocking it for 20 minutes while a herd crosses. Pronghorn antelope, wild burros (they'll stick their heads in your car window), prairie dogs, and mountain goats are common. The annual Buffalo Roundup every September is a spectacular event where cowboys on horseback drive the entire herd across the prairie.
Eastern South Dakota is pure Great Plains - vast, open, and profoundly quiet. The Missouri River bisects the state, and driving along its bluffs offers a different kind of beauty: expansive views, sunflower fields stretching to the horizon, and small towns with populations under 100. The Chamberlain rest stop overlooking the river has a powerful Dignity statue honoring Lakota and Dakota women. This route also connects to Wall Drug (the most famous roadside attraction in America) and Mitchell's Corn Palace.
From bison safety to Badlands sunsets.
Mount Rushmore is most dramatic at sunrise when the morning light illuminates the faces. The lighting ceremony at dusk (summer evenings) is also excellent.
Bison in Custer State Park look docile but can sprint at 35 MPH. Stay in your vehicle. Seriously - they injure more visitors than bears do in Yellowstone.
Needles Highway tunnels are so narrow that RVs and wide trailers cannot fit through. Check height/width restrictions before driving (max 8'4" wide, 12' tall).
Wall Drug is kitsch and knows it. Free ice water (since 1931), 5-cent coffee, and a T-Rex. Budget 30 minutes for the absurdity.
Crazy Horse Memorial is privately funded and still under construction after 70+ years. The face alone is 87 feet tall. Night laser light shows in summer.
Badlands sunsets are extraordinary. Ben Reifel Visitor Center area and the Door/Window/Notch trailhead area face west for optimal sunset viewing.
Monuments carved by nature and by human ambition.
244,000 acres of eroded buttes and pinnacles. The Loop Road delivers the highlights in 31 miles. Notch Trail is the best short hike.
60-foot carved faces of Washington, Jefferson, Roosevelt, and Lincoln. Free entry (parking $10). Most impressive in morning light.
71,000 acres with 1,400 free-roaming bison. Wildlife Loop Road is the highlight. $20/vehicle for 7-day pass.
When finished, will be the world's largest sculpture. The face (87 feet) is complete. Museum and cultural center are excellent.
14 miles of hairpin turns, granite spires, and tunnels carved through solid rock. One of America's most dramatic roads.
One of the longest caves in the world with unique boxwork formations found almost nowhere else. Free park entry; cave tour fees vary.
