South Dakota carved a 1,000-foot gorge near Deadwood and forgot to charge admission

It’s the Black Hills’ best-kept drive

Spearfish Canyon Scenic Byway runs 19 miles along U.S. Route 14A through the northern Black Hills of South Dakota.

Spearfish Creek carved this narrow gorge through limestone walls that rise roughly 1,000 feet on both sides.

The road connects the city of Spearfish to Cheyenne Crossing, near Lead and Deadwood, and the whole thing sits inside Black Hills National Forest. You don’t pay a dime to enter.

Give yourself two to three hours for stops and short hikes, because you’ll want to pull over more than you expect.

The rock here is 600 million years old

The exposed layers along these walls date back roughly 600 million years to the Precambrian era, when a shallow sea sat over everything.

Three rock types stack up from bottom to top: Deadwood Shale, Englewood Limestone, and Paha Sapa Limestone. That top layer alone runs 300 to 600 feet thick.

The highway you drive follows an old railroad grade that flooding wiped out in 1933.

Nobody rebuilt the tracks, and in 1989, the route earned its official designation as a State and Forest Service Scenic Byway.

Bridal Veil Falls drops 60 feet beside your car

About six miles south of the canyon’s north entrance, water comes down 60 feet over a sheer cliff face right next to the highway. That’s Bridal Veil Falls, and you don’t even have to hike to see it.

A wooden observation platform sits near the road for photos. Spring snowmelt pushes the heaviest flow, and by late summer, the falls thin to a trickle.

Look up at the cliffs while you’re there. Mountain goats, first brought to the Black Hills in the 1920s, hang on the ledges near the falls.

Roughlock Falls earned its name from wagon wheels

Little Spearfish Creek feeds Roughlock Falls in the Savoy area, where water drops about 50 feet over a limestone ledge in a series of tiered cascades.

The trail out and back covers roughly 1.8 miles with barely any elevation gain, so families with young children and even strollers can handle it.

The name comes from pioneers who would lock their wagon wheels to keep them from rolling freely down the steep canyon grade. You can hear the water well before you round the last turn.

Spearfish Falls hides behind a restaurant in Savoy

Behind the Latchstring Restaurant in tiny Savoy, a 47-foot waterfall waits at the end of a 1.5-mile round trip trail.

The path drops down into the canyon with moderate elevation change, and a large wooden platform at the base puts you right in front of the cascade.

Fewer people make it here than to Roughlock, so you get a quieter stop.

Both waterfalls share the same parking area near Spearfish Canyon Lodge, which makes hitting them back to back easy.

The creek hasn’t been stocked since the 1960s

Brown, rainbow, and brook trout all swim in Spearfish Creek, and nobody has added a single fish since the 1960s. The population sustains itself.

The creek ranks as the second largest stream in the Black Hills and carries a permanent cold water fishery classification.

It flows fast enough that it freezes from the bottom up instead of icing over on top, so you can fish year-round. April through September gives you the best fly fishing, and you’ll need a South Dakota fishing license.

A gray bird walks underwater on the creek bottom

More than 220 bird species live across the habitats around Spearfish, and the National Audubon Society has designated the canyon an Important Bird Area. One bird makes this place stand apart.

The American Dipper, a stocky gray bird, catches its food by swimming and walking along the stream bottom. If you spot one, you’re looking at a sign of excellent water quality.

Bald eagles, ospreys, canyon wrens, and Lewis’s woodpeckers also show up in the canyon throughout the year.

Fall color peaks here before almost anywhere else

Higher elevation, drier climate, and the mix of tree types push Spearfish Canyon into peak fall color before most of the country catches up.

Aspen, birch, and oak go gold, orange, and red against a wall of evergreen pines. Late September through early October is your window.

The Visit Spearfish website posts weekly fall color reports so you can time your trip. If you only hike one trail during the fall, make it Roughlock Falls.

The color along that path stacks up against anything in New England.

Four ecosystems grow side by side in one gorge

Rocky Mountain, eastern woodland, northern forest, and Great Plains plant communities all overlap here. Ponderosa pine, spruce, aspen, birch, and oak line the canyon floor and climb the hillsides.

Of the 1,585 plant species found in South Dakota, 1,260 grow in the Black Hills, and many of them show up along this drive. White-tailed deer, mule deer, porcupines, raccoons, and the occasional bobcat live in the area.

Keep an eye out for the Pahasapa Mountain Snail, a tiny species found only in the Black Hills.

Winter turns the canyon walls into ice sculptures

When temperatures drop, spots like Community Caves and 11th Hour Gulch go from small trickles to towering ice formations.

Community Caves sits at the end of a steep half-mile hike that calls for crampons or traction spikes.

The trail to Roughlock Falls from Spearfish Canyon Lodge stays open all year, but the road to the falls closes Dec. 15 through March 31 for snowmobile season.

You can snowshoe in to see the falls surrounded by silent, snow-covered forest. Bald eagles show up most often in late fall and winter.

The road has 80 curves and a hydroelectric plant

Kissing Rocks, Split Rock, and Devil’s Bathtub are named rock formations along the byway that give you a reason to pull over.

Near the southern end, the old sawmill town of Savoy once served miners and loggers heading deeper into the hills.

The Homestake Mining Company built a hydroelectric plant in the canyon in 1917 to power its gold mine in Lead using water from Spearfish Creek.

With more than 80 curves on this road, watch for hikers, cyclists, and wildlife around blind corners.

Frank Lloyd Wright drove through and never forgot it

Architect Frank Lloyd Wright visited in 1935, and the canyon left a mark on him. Today, it still draws far fewer crowds than most major national parks and scenic drives.

Deadwood and Lead sit at the southern end of the byway, so you can pair the drive with a trip through those historic towns. From the north, Interstate 90 exits 10 or 14 drop you right into Spearfish.

Mount Rushmore is about an hour’s drive south, making a day trip in either direction simple.

Drive Spearfish Canyon Scenic Byway in South Dakota

You can pick up the byway at either end. From the north, take Exit 10 or 14 off Interstate 90 to reach Spearfish and head south on U.S. Route 14A.

Coming from the south, take Highway 85 east from Wyoming or west from Lead and Deadwood to Cheyenne Crossing.

The canyon and the Spearfish Canyon Nature Area carry no entrance fee, so all you need is gas in the tank, good shoes, and a few hours to spare.
