The 7 Best Waterfalls in South Dakota
South Dakota's waterfall inventory is small and splits neatly in two: the Spearfish Canyon cluster in the Black Hills — three real falls within a few miles of the same scenic byway — and a handful of singular features scattered from the state's namesake city to the warm-water country around Hot Springs, plus a quartzite slot canyon with a Jesse James legend out east.
Every pick here is honestly counted and legally reachable, from a 47-footer that spent 86 years bone-dry after a gold-mine diversion, to a billion-year-old quartzite staircase downtown, to a 67-degree swimming hole. The names that didn't make the list get honest pages instead: Thunderhead Falls, the underground mine-tunnel attraction, closed for good; Grizzly Bear Falls carries an official USGS name but the World Waterfall Database can't confirm the falls actually exists; and 'Remington Falls' appears to be a database artifact whose coordinate lands on an old mine claim. Devil's Bathtub, Spearfish Canyon's beloved plunge-pool chute, isn't in our database yet but belongs on the same road trip.
None of the ranked falls charges a dime. The only fee in South Dakota waterfall country is Custer State Park's — and the man-made Sylvan Lake spillway inside it is a bonus stop, not a pick.
The prettiest falls in the Black Hills — 47 feet of resurrected Spearfish Creek that ran dry from 1917 to 2003 while a gold mine borrowed the water. Short trail down from Spearfish Canyon Lodge, overlook deck for the no-hike view, free, flowing year-round.
Directions, season & rules for Spearfish Falls →Sixty feet of seasonal veil on a limestone wall you can see from your car window on US 14A. Paved accessible platform, zero hiking, best in May-June snowmelt, ice sculpture in winter. The easiest great waterfall stop in the state.
Directions, season & rules for Bridal Veil Falls →Fifty feet of lacy cascades on Little Spearfish Creek with the gentlest trail in the canyon — two miles round trip, benches en route, American dippers working the water. Note the winter wrinkle: the road in from Savoy closes mid-December through March for snowmobile season.
Directions, season & rules for Roughlock Falls →The city's namesake: four stepped falls dropping the Big Sioux River through billion-year-old pink quartzite, with mill ruins beside the water and a five-story tower above it. Free including parking and the tower, open 5 a.m. to midnight, lit at night. The best urban waterfall between Minneapolis and Denver.
Directions, season & rules for Sioux Falls →A low travertine ledge feeding South Dakota's best natural swimming hole — 67-degree spring water year-round, wading shelves for kids, a deeper pocket for everyone else, free Forest Service picnic ground at the trailhead. Go for the swim, stay out of the fast water beyond the main pool.
Directions, season & rules for Cascade Falls →A real two-tier falls of about 15 feet in Devils Gulch, the billion-year-old rose-quartzite slot canyon Jesse James supposedly jumped on horseback in 1876. Free Garretson city park, easy one-mile loop, a crossbridge built specifically to view the falls. Best after snowmelt or rain.
Directions, season & rules for Devils Falls →Fifty feet of 89-degree spring-fed river over sandstone, with 1907 hydro-plant ruins in the canyon — viewed strictly from a donation-supported gazebo by the church lot. The base is posted private and hides a whirlpool cave with a real drowning history. Look, drop a donation, don't descend.
