Small rock-cut tunnel on the US-16 scenic route through the Black Hills—great for framing, leading lines and contrasting texture between rough granite and dense pine. Best at golden hour or under low clouds; autumn adds color. Pullouts nearby but limited parking; watch traffic and stay off the road shoulder. No entry fee; easy roadside access makes quick stops possible. Pairs well with nearby overlooks and Mount Rushmore runs.
