South Dakota Outdoor Guide: Campgrounds, Trails, Beaches & RV Spots
Key Takeaways
- Custer State Park and Badlands National Park together make South Dakota one of the strongest single-state road trip destinations in this whole series — genuine variety within a short drive
- Sylvan Lake is Custer’s “crown jewel” for good reason — swimming, kayaking, and a genuinely scenic shoreline loop, but it gets busy, so arrive early
- Badlands’ Notch Trail involves a real wooden ladder climb — a fun challenge for confident kids, not a casual stroll
- Cedar Pass Campground gets genuinely hot with little shade — an electric site for AC is close to essential in peak summer
The Best Single-State Loop in This Series
