Brainerd to Custer: A Practical Road Trip Guide

The drive from Brainerd, Minnesota, to Custer, South Dakota, covers roughly 580 miles along US-71 and I-90. The route cuts across the prairie pothole region of western Minnesota, where glacial lakes dot the landscape, before entering the Coteau des Prairies, a highland plateau that rises 1,000 feet above the surrounding plains.

After crossing the South Dakota border, the terrain flattens into the James River Valley, then gradually climbs toward the Missouri River and the Badlands. The final push through the Black Hills is a sharp transition from grassland to granite peaks. This journey takes about 9 to 10 hours of pure driving time, so you'll want to break it up with worthwhile stops.

Key natural attractions include Glacial Lakes State Park near Starbuck, Minnesota, where you can hike amid rolling moraines. In South Dakota, stop at the Falls Park in Sioux Falls, a 123-foot waterfall on the Big Sioux River. The Badlands National Park, located about 90 miles before Custer, offers dramatic rock formations.

UNESCO World Heritage Sites: While neither state has a UNESCO site directly on the route, a detour to Pipestone National Monument in Minnesota—30 minutes off I-90—is a culturally significant Native American quarry.

Local commerce thrives in towns like Worthington, MN, and Mitchell, SD, the latter home to the Corn Palace, a Moorish Revival building decorated with agricultural murals. For a deeper dive into hidden gems, check out how to find the best stops and hidden gems between cities.

Culinary stops range from the famous taco joints in Sioux Falls to the German-inspired cuisine in Freeman, SD. Don't miss the cheese curds at a local dairy in the Redwood Falls area.

The route is well-served by US-71 and I-90, with reliable pavement throughout. Primary hazards include deer and livestock crossings, particularly at dawn and dusk, and occasional heavy truck traffic around construction zones.

Fuel prices vary; expect lower costs in South Dakota compared to Minnesota. Plan for a full tank before leaving the Twin Cities area (about 100 miles from Brainerd) and again near Sioux Falls, as rural stretches have limited stations.

• Road quality: mostly good, with occasional potholes in spring.
• Rest areas every 50-70 miles on I-90.
• No tolls on the entire route.

If you're wondering is it worth driving Brainerd, MN to Custer, SD, the answer is a resounding yes—the mix of sights and terrain is unmatched.

Safety on this route is generally good, but weather can be extreme. Summers bring thunderstorms; winters can dump heavy snow and ice. Always check forecasts and carry a winter survival kit.

For families, popular stops include the Children's Museum of South Dakota in Brookings and the Reptile Gardens in Rapid City, just 30 minutes from Custer. Both are rain-friendly and educational.

Pets are welcome at many attractions, but national parks and some monuments restrict them to parking areas. For a break, use the rest areas at mile markers 19, 150, and 250 on I-90, which have pet-friendly walking paths.

Fatigue management is crucial: stop every 2 hours or 150 miles. The town of Murdo, SD, offers a classic dinner at the Cactus Cafe, and Chamberlain boasts a scenic overlook with restrooms and picnic tables.

Hidden off-route spots: The Porter Sculpture Park near Montrose, SD, is a quirky outdoor museum with steel sculptures. Also, the Badlands Loop Road (SD-240) offers a stunning alternate to I-90, but adds 45 minutes.
