Gateway Arch National Park: Best Things to Do, History & Visitor Guide

Most national parks preserve mountains, canyons, forests, deserts, or wild stretches of coastline. Gateway Arch National Park preserves something very different: a pivotal place in the American story.

Standing 630 feet above the Mississippi River in downtown St. Louis, the Gateway Arch has become one of the most recognizable landmarks in the United States. But the stainless-steel monument is only part of the experience. Gateway Arch National Park also includes the Museum at the Gateway Arch, the historic Old Courthouse, landscaped park grounds, and stories that span exploration, westward expansion, Native peoples, migration, slavery, civil rights, architecture, and the growth of St. Louis.

Hi, I'm Rob Decker. I've spent more than 50 years exploring and photographing America's national parks, and Gateway Arch is unlike any other park in the system. Here, the landscape itself is a city, a river, a courthouse, and one extraordinary piece of modern architecture — all connected to some of the most complicated and consequential chapters in American history.

The park encompasses about 91 acres, including the Arch grounds, Old Courthouse, Luther Ely Smith Square, and surrounding areas. The Museum at the Gateway Arch and Old Courthouse are free, while the Tram Ride to the Top requires a ticket.

1. Stand Beneath the Gateway Arch

No photograph completely prepares you for the scale of the Gateway Arch.

The monument rises 630 feet above the St. Louis riverfront and spans the same distance between its two legs. Its stainless-steel surface changes constantly with the weather and light — bright silver under midday sun, blue-gray beneath storm clouds, and sometimes almost golden near sunrise or sunset.

Finnish-American architect Eero Saarinen designed the Arch after winning a national architectural competition held in 1947–48. Construction began in the early 1960s, and the final stainless-steel section was placed on October 28, 1965.

The form is based on a weighted catenary curve, giving the monument its elegant, seemingly effortless shape. Viewed from directly underneath, the two enormous triangular legs sweep upward until they appear almost impossibly narrow at the top.

Walk around it before going inside. The Arch changes dramatically depending on where you stand, and some of the most interesting views come from moving away from the monument rather than standing directly beneath it.

2. Ride the Tram to the Top of the Gateway Arch

The Tram Ride to the Top is the signature Gateway Arch experience. Small tram cars carry visitors inside the monument's curved legs to the observation area 630 feet above St. Louis.

The complete experience generally takes 45–60 minutes, including the ride, pre-boarding experience, and time at the top. The trip upward takes approximately four minutes, while the return takes about three.

At the top, narrow windows provide views in two directions. Look west across downtown St. Louis and east across the Mississippi River toward Illinois. On a clear day, the elevated perspective makes it easier to understand why the Mississippi River was so important to the development of the city.

3. Explore the Museum at the Gateway Arch

Don't make the mistake of riding to the top and leaving. The Museum at the Gateway Arch is one of the most important parts of the park.

Located underground beneath the Arch, the free museum traces more than 200 years of St. Louis and American history through six interactive galleries. Its story begins with the founding of St. Louis in 1764 and continues through the construction of the Gateway Arch in 1965.

The exhibits explore colonial St. Louis, Thomas Jefferson's vision for western expansion, the Louisiana Purchase, the Lewis and Clark Expedition, river commerce, migration, Manifest Destiny, Native peoples, and the profound consequences westward expansion had for the many cultures already living across the continent.

That broader perspective is important. The story of westward expansion cannot be understood only as a story of explorers and pioneers. It is also a story of Indigenous nations, territorial conflict, forced displacement, slavery, changing borders, immigration, commerce, and competing ideas about what the United States would become.

The museum was redesigned to present these interconnected perspectives and encourage visitors to reconsider the traditional narrative of the American West.

4. Visit the Old Courthouse and Learn the Story of Dred and Harriet Scott

Two blocks west of the Arch stands one of the most historically important buildings in St. Louis: the Old Courthouse.

Construction began in 1839, and the building eventually became the setting for hundreds of freedom suits brought by enslaved people seeking their liberty. Among them were Dred and Harriet Scott, who filed separate petitions for freedom in 1846. The first two trials in the Dred Scott case took place here in 1847 and 1850 before the legal battle eventually reached the U.S. Supreme Court.

The courthouse also played a role in the struggle for women's rights. In the 1870s, Virginia Minor challenged laws denying women the right to vote, and her case was heard here before ultimately reaching the Supreme Court.

After extensive renovations, the Old Courthouse reopened to visitors in May 2025 with restored spaces, improved accessibility, and new museum galleries examining civil rights, early St. Louis, westward expansion, and the people whose legal struggles unfolded within the building. Admission is free.

5. Walk the Gateway Arch Grounds and Mississippi Riverfront

Gateway Arch may be America's smallest national park, but its landscaped grounds make it surprisingly enjoyable to explore on foot.

Paths wind through lawns and trees between downtown St. Louis and the Mississippi River. Walking away from the Arch also reveals how carefully the monument was positioned in relation to the city, river, and Old Courthouse.

Luther Ely Smith Square creates a pedestrian connection between the Old Courthouse and Arch grounds, while the riverfront provides a completely different view of the monument. The park contains more than five miles of walking and biking paths, making it easy to extend your visit beyond the indoor attractions.

For photographers, keep moving. The Arch is a rare subject that becomes more interesting as your perspective changes.

6. Understand Why St. Louis Became the "Gateway to the West"

St. Louis occupies a strategic location near the confluence of some of North America's great river systems, helping transform the city into a major center of commerce, exploration, migration, and transportation.

After the Louisiana Purchase in 1803 dramatically expanded U.S. territorial claims, expeditions including Meriwether Lewis and William Clark's Corps of Discovery traveled west through the region. St. Louis became an important point of departure for explorers, traders, emigrants, soldiers, and settlers moving into western territories.

The Gateway Arch was created to commemorate this history and St. Louis' role in the nineteenth-century expansion of the United States. The park also interprets the people and cultures affected by that expansion and the debates over slavery and freedom represented by the Dred and Harriet Scott story.

That complexity is what makes Gateway Arch National Park more interesting than the monument alone. The park asks visitors to consider not only where Americans went west, but why they went, who was already there, what was gained, what was lost, and how those events continue to shape the nation.

7. Look Closely at the Architecture of the Gateway Arch

Even if you're not an architecture enthusiast, the engineering behind the Gateway Arch is fascinating.

The stainless-steel-faced monument is 630 feet tall and 630 feet wide at ground level. Its triangular legs are approximately 54 feet wide at the base but narrow dramatically as they rise toward the observation area. The foundations extend about 60 feet into the ground.

Saarinen's design looks deceptively simple. In reality, constructing two enormous curved legs that had to meet precisely hundreds of feet above the ground required extraordinary engineering and fabrication.

When the final section was installed on October 28, 1965, the two sides aligned and the form that now defines the St. Louis skyline was complete.

8. Photographing Gateway Arch National Park

As a photographer, I find Gateway Arch especially interesting because there isn't one definitive composition. Its shape changes depending on your distance, lens choice, light, and position.

For the classic city view, move west and use the Old Courthouse as a foreground element with the Arch rising behind it. From the Mississippi Riverfront, you can emphasize the relationship between the Arch and the river. Directly beneath the monument, a wide-angle lens exaggerates its sweeping curve and enormous scale.

Early morning often provides cleaner light and fewer people, while late afternoon and evening can create beautiful reflections across the stainless steel. Cloudy or stormy skies shouldn't discourage you — they can make the Arch far more dramatic than a perfectly clear blue sky.

How Much Time Do You Need at Gateway Arch National Park?

You can see the Arch itself quickly, but that doesn't mean you should.

For a first visit, I recommend allowing about four to five hours. That gives you time to ride the tram, explore the museum, visit the Old Courthouse, and walk around the grounds without feeling rushed.

The National Park Service estimates roughly 45–60 minutes for the Tram Ride to the Top, about an hour for the Museum at the Gateway Arch, and another hour for the Old Courthouse Museum. Add security, walking, photographs, and time outside, and a half-day visit makes much more sense than simply stopping for a quick picture.

Before You Visit Gateway Arch National Park

Unlike a wilderness national park, Gateway Arch is located in the heart of a major city. That makes it easy to incorporate into a St. Louis trip, but there are still a few things worth planning in advance.

The Gateway Arch visitor center is reached through the west entrance facing Fourth Street and the Old Courthouse, and visitors pass through airport-style security. The Arch's legs themselves are exits rather than public entrances.

The museum and Old Courthouse are free, but the Tram Ride to the Top is ticketed. Because operating hours, tram availability, events, and ticket prices can change, check the National Park Service and official Gateway Arch websites before your visit.

How much time should you spend at Gateway Arch National Park?

Plan on approximately four to five hours if you want to ride the tram, explore the Museum at the Gateway Arch, visit the Old Courthouse, photograph the monument, and walk the park grounds. Visitors interested primarily in seeing the Arch can spend less time, but a half day provides a much more complete experience.

What is the best time to photograph the Gateway Arch?

Early morning and late afternoon generally offer the most interesting light, but the stainless-steel surface makes the Arch highly responsive to changing weather. Reflections, clouds, fog, storms, and evening light can all create excellent photographs. The Old Courthouse, riverfront, and park grounds provide particularly strong viewpoints.

More Than a Monument

It's easy to arrive at Gateway Arch National Park thinking you've come to see one famous structure. Look beyond the Arch, though, and the park becomes much more interesting.

Ride 630 feet above the Mississippi River. Walk beneath one of the great works of twentieth-century American architecture. Explore the history of St. Louis and the nation's westward expansion. Stand in the courthouse where Dred and Harriet Scott challenged slavery and fought for their freedom.

Gateway Arch National Park doesn't preserve wilderness in the traditional sense. Instead, it preserves ideas, decisions, struggles, ambitions, and stories that helped shape the United States.

And in the middle of it all stands Saarinen's Arch — simple, elegant, enormous, and unmistakable.
