September brings a new rhythm to the Black Hills and Badlands. The mornings feel cooler, the roads invite a slower pace, and the first signs of fall begin to appear across the forested hills, canyons, and open prairie.
It is also a month with plenty of energy. Come for the Custer State Park Buffalo Roundup, stay for scenic drives, outdoor adventures, local events, and the full range of attractions still open across the region.
A September Trip With Two Speeds
September can begin with the last long days of summer and gradually settle into fall. You might spend one day exploring a landmark, another following a scenic route through the Hills, and another enjoying a quiet evening in a historic downtown.
The month’s signature moment arrives at Custer State Park, where approximately 1,500 bison are corralled by cowboys and cowgirls on horseback during the annual Buffalo Roundup. The 2026 Buffalo Roundup and Arts Festival runs Thursday, Sept. 24, through Saturday, Sept. 26, with the roundup taking place Friday morning.
Best For:
- Travelers planning around the Custer State Park Buffalo Roundup

Five September Highlights
1. Feel the Thunder at the Buffalo Roundup
The Custer State Park Buffalo Roundup is one of the region’s most memorable fall traditions. Watch the herd move across the prairie as riders guide the bison toward the corrals, then spend time at the accompanying Arts Festival, which features more than 150 vendors, food, and entertainment.
Plan to arrive prepared for an early morning. Warm layers, comfortable shoes, water, and a camera will help you enjoy the experience.
2. Take the Long Way Through the Hills
September is made for scenic touring. Follow winding roads through pine forests, granite formations, and open landscapes, leaving time for overlooks, short walks, and unexpected stops.
Build your route around places such as Spearfish Canyon, Custer State Park, Iron Mountain Road, and Badlands National Park. The drive is part of the experience, not just the way to get there.
3. Catch the First Colors of Fall
Fall color develops at different times across the region, depending on elevation, location and weather. September may bring early color in some areas while other landscapes remain green.
Keep your route flexible and watch for changing light along canyon roads, forest trails, and scenic overlooks.
4. Spend More Time Outside
Cooler temperatures make September comfortable for hiking, biking, horseback riding, wildlife viewing, and scenic walks. Early mornings and late afternoons are especially inviting for travelers who want to enjoy the outdoors at a relaxed pace.
Give wildlife plenty of space, stay on designated trails, and follow posted guidance in parks and recreation areas.
5. Round Out the Trip With Local Discovery
September is also a good time to slow down in the region’s communities. Explore historic Main Streets, visit museums and galleries, enjoy local dining, or find a seasonal event to add to your plans.
A day in the Black Hills and Badlands does not have to end when the scenic drive does. Staying for dinner, shopping locally, or adding another night gives you more time to experience the region beyond its landmarks.
