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

Custer State Park’s lakes and wildlife paired with Badlands National Park’s otherworldly terrain make South Dakota one of the most complete family road trip destinations covered in this whole guide series.

Campgrounds

About 22 free, first-come primitive sites with no water or electric. Vehicles over 18 feet aren’t allowed. Bison and prairie dogs regularly wander through camp, and the night skies here are some of the darkest in the country.

Hiking Trails

Planning Your Trip

Pair Custer State Park with Badlands National Park for the strongest single trip in this whole series — Sylvan Lake and the granite-spire hikes in Custer, then the ladder climb at Notch Trail and the badlands terrain a couple hours away. Book Custer’s Sylvan Lake and Cedar Pass’s electric sites the moment reservations open; both are the first to go.
