Every September, the Buffalo Roundup takes over custerstateparksd as cowboys and cowgirls bring the park's herd across the prairie and into the corrals. 🦬 It's become one of South Dakota's biggest annual traditions, but as you'll see in the video, there's an important reason behind it too. The roundup helps park staff care for the herd, carry out health checks and manage bison numbers to protect the grasslands they depend on. And yes, you can watch it all happen. 📅 September 25, 2026 ⏰ Roundup begins at 9:30am MT 🚗 Parking opens at 6:15am 📍 Custer State Park, Black Hills Would you get up at 6am to see this? #HiFromSD
