One road in the Black Hills threads through rock walls so narrow you hold your breath driving it

The Black Hills’ boldest drive

You could spend a week in the Black Hills and still not fully account for what Needles Highway does to you.

In 14 miles, it threads through pine forest, climbs granite mountains, narrows to a single lane inside solid rock, and opens up to a lake so clear it looks painted. Most people drive it in under an hour.

Most people also stop every quarter mile. Start early, and the light will be with you.

A road engineers said couldn’t be built

Peter Norbeck didn’t call an engineering firm when he planned this highway. He walked it.

He rode it on horseback. Then, sometime around 1920, he told builders to cut a road through terrain his own engineers called impossible.

They finished in 1922, and the 14 miles they carved through the Black Hills became the spine of what grew into the 70-mile Peter Norbeck National Scenic Byway, later recognized as one of the 10 most outstanding byways in North America.

Your car squeezes through solid rock walls

The tunnels are the part people talk about for years.

The highway punches through solid granite in several places, and the tightest passage runs about 8 feet wide. You take turns with oncoming traffic, one car at a time.

If you pull over at the nearby overlooks and watch, you’ll see drivers inch through with a few inches to spare on each side. RVs and large trailers won’t make it, so check your vehicle dimensions before you head in.

Stand in front of the Needle’s Eye

Near the highway’s highest point, thousands of years of wind, rain, and freeze-thaw cycles carved a narrow hole through a granite spire. The opening looks exactly like the eye of a giant sewing needle.

A pull-off lets you park and walk up close. It’s the most photographed formation in the park, and it earns it.

The scale surprises most people. Photos flatten it.

Standing in front of it, you understand why Norbeck fought so hard to run a road through here.

Sylvan Lake waits at the top of the drive

At the northern end of the highway, the road deposits you at Sylvan Lake, which sits at about 6,145 feet and covers roughly 17 acres.

Theodore Reder created it in 1881 by damming Sunday Gulch Creek, and massive granite formations ring the water on every side.

You can swim here, kayak, canoe, rent a paddle boat, or fish for rainbow trout with a valid South Dakota license. A one-mile loop trail circles the whole lake and works for every fitness level.

Cathedral Spires rise over six granite ridges

About 2.5 miles east of Sylvan Lake, six ridges of granite pillars erupt from the hillside in a cluster called the Cathedral Spires.

The 637-acre area earned National Natural Landmark designation in 1976, and a roughly 1.6-mile round-trip trail gains about 500 feet to reach the base of the spires. Mountain goats move through the rocks up here regularly.

The trail connects to the Little Devils Tower route, which climbs higher and opens up the full sweep of the Black Hills below you.

This was almost where Mount Rushmore went

In the 1920s, the Needles were the first choice for South Dakota’s famous mountain carving. State historians and boosters wanted to sculpt figures of Native Americans and pioneers into these spires.

Sculptor Gutzon Borglum came, looked, and said no. The granite was too thin and fractured to hold large carvings.

He found a 400-foot cliff about 30 minutes north and built Mount Rushmore there instead. The Needles stayed exactly as they were, which is why you can stand here today looking at what Borglum passed on.

Trails drop into canyons and climb to the summit

The trailheads along the highway connect to some of the best hiking in the Black Hills. Sunday Gulch Trail runs about 3 miles in a loop with ladders, handrails, rock scrambles, and small waterfalls.

The Cathedral Spires Trail puts you at the base of the pillars.

The biggest climb starts at Sylvan Lake and covers roughly 7 miles round-trip to Black Elk Peak, the highest summit east of the Rocky Mountains at 7,242 feet, with about 1,100 feet of elevation gain.

Climbers have worked these rocks since the 1930s

Fritz Wiessner made the first recorded ascents on formations like the Totem Pole and Khayyam Spire back in the 1930s, and climbers have been returning ever since.

The granite here runs beginner routes through multi-pitch advanced lines, and the Cathedral Spires area alone has five main ridges worth of climbing.

Local outfitters near Sylvan Lake guide trips for all experience levels.

If you’ve never climbed before and want to try it against a backdrop like this, this is a reasonable place to start.

Bison, mountain goats and begging burros roam free

Custer State Park covers more than 71,000 acres, and it manages a free-roaming bison herd of more than 1,300 animals, rounded up every September.

The mountain goats along the Needles and near Black Elk Peak descend from a small group that escaped a local zoo in 1924 and never came back.

Drive the 18-mile Wildlife Loop Road, which connects to the highway, and you’ll likely cross paths with elk, pronghorn, mule deer, bighorn sheep, and the park’s famous burros, which will walk right up to your car window.

What you need to know before you drive it

The highway runs 14 miles along South Dakota Highway 87 and generally stays open from early April through mid-October, closing with the first snow.

Plan on 45 to 60 minutes of actual driving at 25 mph or slower. Custer State Park charges $20 per vehicle for a one-to-seven-day pass.

Leave the RV or anything towing a large trailer behind. The tunnels and hairpin turns won’t fit them.

Get there early in the morning for thinner crowds and the best odds of seeing wildlife moving through the meadows.

Come back in winter and walk where the cars can’t go

When snow closes the highway to vehicles, it opens to a different kind of visitor.

You can walk the 14 miles on foot, on snowshoes, or on cross-country skis through a landscape that most people never see. The 300,000 visitors who come each year almost all come in the warmer months.

The highway also connects to Iron Mountain Road, which frames Mount Rushmore through its own tunnels, making the two drives a full day of back-to-back scenic road travel that covers some of the most dramatic terrain in the American West.

Explore Custer State Park in South Dakota

Custer State Park sits about 30 miles south of Rapid City, in the heart of the Black Hills.

The park is open 24 hours a day and charges $25 per vehicle for up to seven days of access, which covers Needles Highway, the Wildlife Loop Road, Sylvan Lake, and all nine campgrounds and four historic lodges.

Nearby, you can reach Mount Rushmore in about 30 minutes, or visit the Crazy Horse Memorial, Wind Cave National Park, and Jewel Cave National Monument.
