Where Iowa, Nebraska and South Dakota collide on the Missouri River

Sioux City’s a three-state town

Sioux City sits in northwestern Iowa, right where the Missouri River pulls three states together. Locals call the whole metro area “Siouxland” because it bleeds into South Dakota and Nebraska.

You get more than 35 parks, over 30 miles of trails, and a walkable riverfront that makes the city feel bigger and greener than you’d expect.

Most of the museums and nature centers cost nothing to get in, and the real draw is a geological oddity you won’t find anywhere else in the Western Hemisphere.

The city grew up on river trade and cattle

The city took its name from the Sioux tribe who lived in the region long before settlers arrived in 1854. Lewis and Clark’s Corps of Discovery came through in the summer of 1804, and that connection still runs deep here.

Sioux City also marks the navigational head of the Missouri, the farthest point upstream where large boats could travel. By the late 1800s, river trade and meatpacking turned it into a boomtown.

Today you get that frontier history mixed with modern food spots, live music, and trails that start right in town.

Walk ridges thinner than your car on the Loess Hills

The Loess Hills stretch about 200 miles along Iowa’s western border, built from wind-deposited soil that can run 200 feet deep. The only place on Earth with loess formations this thick is Shaanxi, China.

Some of the ridges narrow to less than 10 feet across, with steep drop-offs on both sides. Locals call the soil “sugar clay” because it turns rock-hard in dry weather and dissolves in rain.

The Loess Hills National Scenic Byway runs about 220 miles and passes right through the Sioux City area.

Stone State Park drops you into 1,600 wild acres

Right on the city’s northwestern edge, Stone State Park covers nearly 1,600 acres at the northern tip of the Loess Hills.

The Civilian Conservation Corps built the park’s stone entrance portals and a rustic lodge back in the 1930s, and they still stand.

You can hike, mountain bike, ride horseback, or cross-country ski on more than 15 miles of trails. From the overlooks, you look out over wooded valleys, the Big Sioux River, and clear into South Dakota and Nebraska.

White-tailed deer, wild turkey, coyotes, and red foxes move through the woods. On the steep ridges, yucca and pasque flowers grow the way they did centuries ago.

Live hawks and owls at Dorothy Pecaut Nature Center

This 14,000-square-foot nature center sits inside Stone State Park and digs into the ecology of the Loess Hills. You walk through exhibits on native plants, animals, and the geology that makes this landscape so unusual.

Live fish, reptiles, and raptors are housed on-site, including a red-tailed hawk and a barred owl in the outdoor Raptor House. Three miles of pedestrian-only trails wind through forest and over steep prairie ridges.

Kids get the Discovery Forest Nature Playscape, an outdoor play area built with natural materials. Trained naturalists lead programs year-round, from summer camps to bird-watching hikes.

Step inside a free Lewis and Clark museum on the river

The Lewis and Clark Interpretive Center spreads across nearly 20,000 square feet along the Missouri River and covers the expedition’s time in the area from July to September of 1804.

You walk past hand-painted murals, animatronic figures, and interactive displays, then sit down in the Keelboat Theater for a short film.

Next door, the Betty Strong Encounter Center rotates exhibitions on agriculture, river life, and Native heritage. The whole complex sits in a riverside park with picnic areas and walking paths.

It costs nothing to visit and stays open Tuesday through Sunday.

A 100-foot obelisk marks the expedition’s only death

Sergeant Charles Floyd died on Aug. 20, 1804, likely from a ruptured appendix.

He was the only member of the Lewis and Clark Expedition to die on the journey and the first U.S. soldier to die west of the Mississippi. A 100-foot sandstone obelisk, finished in 1901, marks his gravesite on a bluff above the Missouri River.

The monument sits in a 23-acre park and was among the first National Historic Landmarks in the country.

Nearby, the Sergeant Floyd River Museum fills a retired Army Corps of Engineers inspection boat docked on the riverfront. Admission is free.

The courthouse Frank Lloyd Wright’s mentor helped design

The Woodbury County Courthouse went up in 1918, and people still consider it one of the finest Prairie School buildings in the country.

Architect William Steele designed it alongside George Grant Elmslie, who trained under Louis Sullivan right alongside Frank Lloyd Wright.

You walk in past sculptural work by Alfonso Iannelli over the entrances, then through marble floors, a stained-glass dome, and ornate terra cotta detailing. A 157-foot tower rises above the four-story brick building.

Interior murals by John W. Norton line the walls.

The courthouse earned National Historic Landmark status in 1996, and the county still runs business out of it today.

Three lost chandeliers hiding above a drop ceiling

The Orpheum Theatre opened in 1927, built by the Chicago firm Rapp and Rapp for the Orpheum vaudeville circuit.

It seated about 2,650 people and came with a Wurlitzer pipe organ, crystal chandeliers, hand-carved detailing, and a hand-painted ceiling. Decades of decline split it into two movie houses before it closed in 1992.

Then came a nearly $12 million restoration. During renovation, workers found three original crystal chandeliers still intact above a drop ceiling. The Orpheum reopened in Sept. 2001 and now hosts Broadway touring shows, concerts, and the Sioux City Symphony Orchestra.

Tube down a 700-foot snow hill, then bike it in summer

Cone Park covers 35 acres and changes with the seasons.

In winter, you race down a 700-foot snow tubing hill or glide across a 5,400-square-foot outdoor ice rink. A day lodge gives you a warming area, concessions, and an outdoor fire pit.

When the weather turns, the ice rink becomes a free splash pad and a summer tubing hill opens up. Mountain bikers get 10.5 miles of trails, a pump track, and progressive jump lines for every skill level. A two-mile trail loop connects Cone Park to nearby Sertoma Park.

Handmade Bing bars and loose meat since 1955

The Palmer family landed in Sioux City in the late 1800s and started a wholesale grocery business. By 1923, they introduced the Bing candy bar, a cherry nougat center coated in chopped peanuts and chocolate.

Workers still make each one by hand, and it ranks among the biggest-selling handmade candy bars in the country.

Palmer’s Olde Tyme Candy Shoppe near I-29 has a small museum with antique candy-making equipment and hundreds of selections.

Down the road, Tastee Inn and Out has served Sioux City since 1955 with its famous loose meat “Tastees” and crispy onion chips with dip.

A stainless steel Virgin Mary towers over garden grounds

Trinity Heights covers 16 acres on the north side of town, where towering stainless steel sculptures of Jesus and the Virgin Mary rise above the trees.

A life-sized hand-carved wooden sculpture of the Last Supper draws visitors of all backgrounds. The Sioux City Art Center, which costs nothing to enter, rotates exhibitions from local and nationally known artists.

Its permanent collection leans into the Regionalist movement, and Grant Wood’s Corn Room mural is under conservation with a planned return in 2026.

A few blocks away, the Fourth Street Historic District lines up Romanesque commercial buildings dating from 1889 to about 1915.

Explore Siouxland where three states meet in Iowa

You can start at the Lewis and Clark Interpretive Center and the Sergeant Floyd River Museum, both free, both right on the Missouri River.

From there, head to Stone State Park and the Dorothy Pecaut Nature Center to hike the Loess Hills ridges you won’t find anywhere else in the Western Hemisphere. Cone Park keeps the whole family busy in every season.

Before you leave, stop at Palmer’s Olde Tyme Candy Shoppe for a handmade Bing bar and grab a loose meat sandwich at Tastee Inn and Out.

Sioux City sits at the crossroads of Iowa, South Dakota and Nebraska, about 90 miles north of Omaha off I-29.
