The Sanford Pentagon on West Pentagon Place is the region's premier athletic facility — the nine-court basketball arena, training spaces, and event venues that host everything from high-school tournaments to collegiate showcases to the occasional NBA G League game. Sioux Falls hosts serious basketball here. The facility runs camps, clinics, and league play for kids working on their game, plus fitness programming for adults who want to share the court with their teenager once in a while. The architecture alone is worth the walk-through — exposed brick, natural light, and the kind of hardwood that makes every weekend tournament feel bigger than the box score.
