If you’ve ever driven across South Dakota, you know it’s more than just wide-open spaces and long stretches of highway. It’s a state packed with unforgettable stories, scenic beauty, quirky roadside stops, and rich history.
On our family road trip in 2021, we discovered that every little detour off I-90 brought something incredible: a legendary drug store with free ice water, ancient rock formations that look out of this world, and historic rock carvings.
In this post, I’m sharing our favorite things to do in and around Wall, Spearfish, Custer, and Keystone—including hidden gems, meaningful moments, and travel tips you can use to plan your own South Dakota adventure.
Whether you’re chasing waterfalls, collecting pressed pennies, or dreaming under a sky full of stars, you’ll find something here that will stick with you long after the trip is over.
South Dakota Things to do in Wall
Wall Drug
What began as a small-town pharmacy has become one of the most iconic roadside attractions in America. Wall Drug, located in Wall, South Dakota, opened in 1931 with a simple offer: free ice water for thirsty travelers crossing the hot prairie. That promise still holds true today—and it’s part of what launched Wall Drug into roadside legend.
A few years after opening, the owners, Ted and Dorothy Hustead, started putting up handmade billboards along nearby highways to draw in more visitors. Those clever signs worked—and then some. Today, you’ll find more than 300 Wall Drug billboards scattered across the country. We started spotting them as early as Nebraska on our drive from the Kansas City area! That’s marketing genius if you ask me—and it works! Wall Drug attracts about 2 million visitors every year.
When we stopped in, we grabbed a donut and of course, some of that famously free ice water. It was delicious! Ever since I was pregnant with Jackson, I absolutely LOVE ice water! It is so refreshing. I also picked up a t-shirt with a replica of one of the classic “Free Ice Water” signs, and I’ve had several people comment on it since—it’s a fun conversation starter.
What I love most about Wall Drug isn’t just the kitschy charm or the donuts—it’s the story behind it. On their website, they share this quote:
“Free Ice Water. It brought us Husteads a long way and it taught me my greatest lesson, and that’s that there’s absolutely no place on God’s earth that’s Godforsaken. No matter where you live, you can succeed, because wherever you are, you can reach out to other people with something that they need.”
That message really stuck with me. It’s a reminder of what’s possible with creativity, kindness, and a little hustle. Wall Drug isn’t just a stop—it’s a slice of the American dream.
Minuteman Missile National Historic Site
Just off I-90, east of Wall, South Dakota, you’ll find a unique and sobering stop: the Minuteman Missile National Historic Site. During the Cold War, dozens of these missile sites were scattered across the Great Plains. Their purpose? To be ready at a moment’s notice to protect the United States from potential threats.
The missiles earned the name Minuteman because they could be launched in under a minute. This is a scary reminder of how quickly things could escalate. These intercontinental ballistic missiles (ICBMs) were on alert 24 hours a day, 7 days a week, for over 30 years. It’s a powerful glimpse into a tense chapter of American history and the conflict between the United States and the Soviet Union.
Here is a fun fact: There’s actually a decommissioned missile silo in central Kansas that’s been converted into an Airbnb! We’re hoping to book a stay there next time we’re passing through Kansas—how wild is that?
If you’re a history buff or fascinated by the Cold War era, this site is absolutely worth a visit. The visitor center is free and does not require a park pass. However, if you’d like to explore specific areas like the underground launch control center or the Delta-09 missile silo, you’ll need to join a ranger-led tour. These tours do require a reservation and a small fee—but they offer a much deeper dive into the story behind the site.
Badlands National Park
I’ll never forget the moment the Badlands came into view as we drove west on I-90 toward Rapid City. Wow. That’s really all I could say. The layered rock formations, glowing in the sunlight as we approached, were unlike anything I had ever seen. It’s the kind of beauty that’s hard to put into words—you don’t just see it, you feel it.
Once inside the park, we stopped at the first scenic overlook to get out and take it all in. The vastness, the colors, the stillness—it was breathtaking. After that, we visited the visitor center and attempted a hike. In hindsight, we should have done a little more research before setting out. The trail we chose had a steep incline with lots of loose pebbles, making it tough to get solid footing. So here’s my tip: if you plan to hike in the Badlands, look up the trail details ahead of time and choose one that matches your comfort level.
Even if you’re not up for hiking, you can still experience the park’s beauty from your vehicle. The scenic drive winds through otherworldly rock formations and dramatic overlooks—you don’t have to step outside to be amazed.
I Recommend Stargazing at the Badlands
There’s so much more to explore in the Badlands, and on our next trip, I’m determined to try stargazing. After experiencing the dark skies at Little Jerusalem Badlands State Park in western Kansas over Labor Day weekend—where we stayed late to photograph the stars—I gained a whole new appreciation for the night sky. It’s wild how much light pollution we live with in the city. That trip helped me realize just how magical the stars can be when you’re far from the noise and glow. Plus…I got to see and photograph the Milky Way! Amazing!!!
So next time we’re in South Dakota, stargazing in the Badlands is at the top of my list. I can only imagine how stunning the Milky Way looks above those timeless formations.
South Dakota Things to do in Spearfish
Spearfish Canyon Scenic Byway
We started our day by leaving Deadwood and grabbing breakfast at Cheyenne Crossing—and let me tell you, it was so good! After filling up, we hopped into Jude (our trusty Nissan Armada) and headed north on the Spearfish Canyon State and National Forest Service Scenic Byway.
This part of South Dakota is absolutely breathtaking. In fact, after my husband passed away, my therapist guided me through a visualization exercise to help me find peace—and Spearfish Canyon was the place that came to mind. The way the river gently winds alongside the road, framed by steep canyon walls and tree-covered hills, is calming in a way that’s hard to describe. There’s something about the way the water cuts through the land that reminds me of the Irish countryside—serene, lush, and timeless.
Although we didn’t stop at the roadside waterfalls (they were packed with people—peak summer right after COVID), we did find a quieter trail leading to a smaller waterfall nearby. It was a short hike, but the heat that day caught us off guard—it felt more like Kansas in July than the Black Hills of South Dakota!
If you’re planning a visit, I highly recommend checking out the self-guided tour of Spearfish Canyon Scenic Byway available on the City of Spearfish website. One of the stops even features the Dances with Wolves Winter Film Site—a fun extra if you’re a fan of the movie like I am.
Whether you’re healing, exploring, or just taking in the beauty, a drive through Spearfish Canyon is good for the soul.
Cheyenne Crossing
What a hidden gem! Before our drive through the breathtaking Spearfish Canyon, we kicked off the morning with breakfast at Cheyenne Crossing, and it did not disappoint. Jackson and I split a classic plate of scrambled eggs, crispy bacon, and toast—it was simple, hearty, and hit the spot.
Before we hit the road again, we wandered into the gift shop attached to the café—and that’s where I found one of my all-time favorite t-shirts. Picture this: two cartoon bears staring at a stick-figure family decal on the back of a station wagon, with the caption: “Look, a menu!” People ask me about it all the time. (Fun twist: I later found the exact same shirt in Sedona, Arizona—apparently bear humor travels well.)
But Cheyenne Crossing isn’t just a great spot for food and fun souvenirs—it’s also rich in history. Originally established in 1878, it served as a stagecoach stop for travelers heading west. It’s amazing to think how many stories have passed through those same walls over the last century and a half.
If you’re looking to stay in the area a bit longer, Cheyenne Crossing also has a charming upstairs lodge that sleeps up to nine guests—perfect for families or small groups looking to soak up the beauty of the Black Hills.
Waterfalls
One of the best things about Spearfish Canyon is how easy it is to experience jaw-dropping natural beauty without much effort. If you’re road-tripping through, these three waterfalls are all accessible, photogenic, and packed with charm.
Bridal Veil Falls
Cascading nearly 60 feet straight down the cliffside, Bridal Veil Falls is the first major waterfall you’ll spot from the byway—and you can’t miss it. Literally. It’s right next to the road! There’s a pull-off with a viewing platform that’s perfect for snapping that Instagram-worthy photo without even breaking a sweat. It’s a quick stop, but one of the most photographed sights in the Black Hills for good reason.
Roughlock Falls
If you’re up for a short stroll, Roughlock Falls is your reward. The name comes from pioneer days, when travelers had to “roughlock” their wagon wheels—tying them off to keep from rolling uncontrollably down the steep canyon. These days, thankfully, the path is far less treacherous. There’s convenient parking, clean restrooms, picnic spots, and a gentle walking path that leads right to the multi-tiered falls. It’s peaceful, scenic, and absolutely worth your time.
Spearfish Falls
This one’s a bit of a hidden gem. You’ll find the trailhead for Spearfish Falls just behind the Latchstring Inn. The short hike winds down into the canyon and rewards you with a dramatic view of the falls thundering into the creek below. The sound of the water echoes through the trees—it’s one of those places that makes you feel small in the best way. Just a heads-up: the trail can get slick, so good shoes are a must. If hiking’s not in the cards, no worries—there’s also an overlook deck for a great view from above.
South Dakota Things to do in Custer
Annual Buffalo Round Up
This is one event that’s been at the top of my bucket list ever since I first heard about it—and for good reason. Every fall, Custer State Park hosts the Annual Buffalo Roundup, where around 1,300 bison thunder across the plains in a scene straight out of the Old West.
The roundup isn’t just for show—it’s a working event where the bison are gathered, tested, branded, and sorted by park staff and real-life cowboys and cowgirls. It’s wild, it’s dusty, and it’s unforgettable.
If you’re planning to attend, prepare for an early morning. The park gates open at 6:15 a.m., but the die-hards recommend arriving even earlier to claim a good spot in the designated viewing areas. Bring lawn chairs, binoculars, warm layers, and maybe a thermos of coffee—then get ready to feel the ground shake as the herd storms past. The action typically begins around 9:15 a.m., and yes—it’s worth the wait.
To make a day of it, you’ll also find breakfast and lunch available for purchase, plus an arts and crafts festival happening alongside the main event. It’s a fantastic way to experience South Dakota’s culture, history, and rugged beauty—all in one unforgettable day.
Needles Highway
I love, love, love Needles Highway—it’s one of the most unforgettable drives we’ve ever done! We experienced it as part of an all-day tour, riding through in a comfy tour bus, and it was absolutely magical. But whether you’re in a bus, car, or on a motorcycle, this 14-mile stretch of road in Custer State Park is pure South Dakota magic.
Winding through towering granite spires and narrow rock tunnels, Needles Highway is best enjoyed slowly—really slowly. With a speed limit of 25 mph and plenty of photo-worthy stops, the full drive takes about an hour, and trust me, you won’t want to rush a second of it. Every turn reveals a new view that will have you reaching for your camera (or just staring out the window in awe).
What’s even more incredible is the story behind it. Needles Highway was completed in 1922, and the route was personally mapped by former South Dakota Governor Peter Norbeck—on foot and horseback! Can you imagine scouting that rugged terrain without modern equipment, just pure vision and determination? It blows my mind to think of what people accomplished back then with grit, passion, and a deep love for their land.
Cathedral Spires Trail
One of my favorite parts of Needles Highway is the surreal landscape of granite spires—those jagged, needle-like formations that seem to erupt straight out of the earth. They’re dramatic, towering, and almost otherworldly.
If you want to do more than just admire them from the road, the Cathedral Spires Trail is your chance to step right into the heart of this stunning scenery. This 1.6-mile (one-way) trail leads you through a narrow valley flanked by towering rock formations that feel like the stone pillars of a natural cathedral.
The hike is moderately challenging, with a few rocky sections and steady elevation gain, but the payoff is absolutely worth it. Surrounded by massive spires and sheer cliffs, you’ll feel completely immersed in the rugged beauty of the Black Hills.
It’s peaceful, awe-inspiring, and a must-do for anyone who wants to experience the magic of the Needles up close.
Needle’s Eye Tunnel
Okay, we have to talk about Needle’s Eye Tunnel. I mentioned earlier that we took a tour bus through Needles Highway—but what I didn’t tell you is that this massive bus actually squeezed through one of the narrowest and most iconic rock tunnels in the Black Hills. And yes, it was just as intense (and impressive) as it sounds!
The tunnel itself is only 8 feet 9 inches wide and 9 feet 8 inches high—barely wide enough for a single vehicle, let alone a full-size bus. So picture this: you’re on a giant tour bus, creeping toward a stone tunnel that looks like it was carved for a golf cart, not a motor coach. Everyone on board is holding their breath, and somehow—miraculously—the bus inches through without a scratch. We’re talking inches to spare. It was like watching a real-life game of Tetris!
And why is it called Needle’s Eye? Look closely at the towering granite spire beside the tunnel, and you’ll see a perfectly formed hole near the top—shaped just like the eye of a needle. It’s one of the most photographed landmarks in Custer State Park, and once you see it, you’ll understand why.
This tunnel is not just a tight squeeze—it’s a jaw-dropping moment you won’t forget.
South Dakota Things to do in Keystone
Rush Mountain Adventure Park
Keystone has earned its nickname as the “playground of the Black Hills,” and Rush Mountain Adventure Park definitely lives up to the hype! This place is packed with fun, and it’s perfect for families looking to add a little adrenaline to their trip.
While we were there, my husband and Jackson couldn’t wait to try the zipline—and they came off grinning ear to ear. They also rode the alpine coaster, which winds down the mountain with just the right mix of speed and scenery. The best part? You can control your own pace, so it’s perfect whether you’re a thrill-seeker or prefer a more relaxed ride.
Penny Press Machines
The thing that really makes us feel like we are getting wrapped up in an adventure is looking for penny press machines. We are huge fans of pressed penny machines—they’re one of our favorite little traditions when we travel! If you’ve never tried one, you’re missing out on a simple and affordable souvenir that’s full of charm. These machines take a shiny penny and a few coins (usually 50 cents to $1) and imprint a unique design that reflects the location you’re visiting.
In Keystone, there are currently seven different penny press locations, each with its own fun designs. One of the best parts of our trip was hunting them down, checking out all the different images, and choosing the one that best captured our experience. Whether it’s a Mount Rushmore silhouette, a buffalo, or a scene from the Black Hills, each penny tells a little story.
They’re easy to collect, easy to carry, and make for a fun scavenger hunt while exploring the area. If you’ve got kids (or a kid at heart), definitely add this to your Black Hills must-do list!
