Badlands

Sharply eroded buttes and pinnacles rising from the largest protected mixed-grass prairie in the US — bison, bighorn sheep, and some of the richest fossil beds on Earth.

⚠️Wildlife & Terrain SafetyBison, 30+ mph
🦬 Bison can run over 30 mph and cause fatal injuries — keep at least 100 feet away, always. Prairie rattlesnakes hide in shaded crevices and boardwalks; watch where you place hands and feet. The eroded badlands terrain causes most park injuries through falls, especially in the wrong footwear — wet clay buttes turn dangerously slick. Summer temperatures frequently top 100°F with little shade, and lightning can strike well ahead of a visible storm. Cell service is unavailable through most of the park, so carry a map and don't rely on your phone. NPS safety info ↗
