Exploring the Iconic Gateway Arch: A Comprehensive Guide for Tourists

When the two legs of the Gateway Arch finally met at the keystone on October 28, 1965, construction crews had to force the steel legs 8.5 feet apart using hydraulic jacks; the sun had expanded one leg just enough that the pieces would not otherwise align. The final gap had a margin of error of less than half a millimetre. No one died during the entire build, the project finished on time, and it came in under budget. That combination, for a structure of this scale and ambiguity, is as remarkable as the shape itself.

What You Are Actually Looking At

The Arch is 630 feet tall and 630 feet wide at the base, a deliberate square proportion. It follows an inverted catenary curve, the same shape a chain makes when held loosely at both ends and allowed to hang freely under gravity. Eero Saarinen won the design competition in 1947, though the telegram announcing the result was initially sent to his father, architect Eliel Saarinen, by mistake. The family opened champagne before a follow-up call corrected the error. Eero died of a brain tumour in 1961, four years before the Arch was completed.

The engineering was largely worked out by Fred Severud’s firm. The structure uses orthotropic engineering: the stainless-steel inner and outer skins are themselves the load-bearing members, not a conventional skeleton of interior girders. Construction required nearly 900 tons of stainless steel, more than any other project in history up to that point.

The Tram: Book It Before Anything Else

Inside each leg runs a tram system that carries visitors to the observation deck at the top. The trams are not conventional lifts. Each car is a set of five small egg-shaped capsules mounted on a pivoting frame so they stay level as the tram follows the curve of the leg. Each capsule holds five people, and the ascent takes approximately four minutes. Time at the top is limited to around ten minutes before you descend via the other leg.

Tram tickets cost approximately $15 for adults (16+) and $11 for children (ages 3-15). These are timed-entry slots and they sell out, especially on summer weekends, often months in advance. Book through the official Gateway Arch website as soon as your travel dates are confirmed. The first tram slot of the day is the least crowded for views from the top; mid-morning onwards tends to be busier.

Hours vary by season. Extended summer hours (Memorial Day through Labor Day) run 9 AM to 8 PM on Fridays and Saturdays, and 9 AM to 6 PM Sunday through Thursday. Standard hours outside summer are 9 AM to 6 PM daily.

The observation windows at the top are small and angled, about the size of a large shoebox laid on its side. The view west takes in downtown St. Louis and Clayton; east you see the Mississippi River curving toward Illinois. On a clear day the horizon extends 30 miles in each direction.

The Museum Below

Beneath the Arch, the Gateway Arch Museum covers westward expansion in the US from the Lewis and Clark expedition through the frontier period. The museum was renovated and reopened in 2018 and the interpretive quality is considerably better than the original 1970s version. Admission is free for the museum itself; you only pay the tram fee if you want to go to the top.

The adjacent Old Courthouse, where the early hearings of the Dred Scott case took place in the 1850s, completed a $24.5 million renovation in 2026. The restored courtrooms and new museum galleries are open and free to enter without tickets.

Where to Eat Near the Arch

St. Louis has a serious barbecue tradition and two of the best places are close enough to the Arch to matter for planning purposes. Pappy’s Smokehouse in Midtown has been the standard-bearer for years: ribs smoked over apple and cherry wood, sold until they run out (usually early afternoon on weekends). Sugarfire Smoke House has multiple locations and broader hours, with pulled pork and burnt ends worth the detour.

For a different angle on local food, St. Louis-style pizza has a specific character: ultra-thin cracker crust, cut in squares, topped with Provel cheese (a local processed blend of Swiss, provolone and white cheddar). Imo’s Pizza is the institution for this style and polarises visitors reliably, which tends to indicate authenticity.

Soulard, about 20 minutes south of the Arch on foot or a short ride, is the city’s oldest neighbourhood and has the best concentration of independent restaurants and bars. The Soulard Farmers Market runs year-round on Saturdays.

Where to Stay

The Drury Plaza Hotel at the Arch sits directly on the riverfront a few blocks from the Arch’s north leg. Rooms on upper floors face the Arch and river; the sight of the structure lit at night from a hotel window is worth paying slightly more for. It sits in the upper-mid price range.

The Angad Arts Hotel in Grand Center, further west, is a design hotel where rooms are themed by colour and each guest’s mood at check-in nominally influences the room assignment. This is a marketing device more than a practical system, but the building itself, a converted 1920s theater, is genuinely impressive and the neighbourhood is walkable to the Fox Theatre and St. Louis Symphony.

Budget options in the immediate downtown area are limited; Soulard and the Benton Park neighbourhood have more affordable accommodation and better access to local life.

Beyond the Arch

The City Museum is the most genuinely original attraction in St. Louis and nothing about the name prepares you for it. It occupies a former shoe factory and is filled with salvaged architectural elements (gargoyles, bridge sections, industrial machinery) welded and rearranged into a building-size climbing structure for adults and children alike. There are tunnels, slides, caves, a rooftop Ferris wheel, and a school bus suspended over the edge of the roof. It is not a museum in any conventional sense. Go on a weekday evening when the adult bar is open and the child-to-adult ratio shifts.

The Saint Louis Zoo in Forest Park is free, one of the genuinely large and well-maintained free zoos in the US, and worth an afternoon. Busch Stadium for a Cardinals game is a dependable warm-weather option; the stadium itself is open-air and has good sightlines from most seats.

For the tram, book the first available slot on the day you arrive, confirm your time before walking to the Arch, and keep your confirmation on your phone; the security checkpoint at the entrance is the point of no return for late arrivals.
