The Gateway Arch is a 630-foot (192 m) stainless-steel arch on the Mississippi riverfront in St. Louis, Missouri, completed in 1965 as a monument to westward expansion and St. Louis's historic role as the "Gateway to the West." Since 2018 it has been part of Gateway Arch National Park, one of the smallest national parks in the US system at about 91 acres and unusual for sitting in the heart of a major downtown. As of mid-2026, visitors can still ride the enclosed capsule tram to the observation deck, and the underground Visitor Center houses a museum covering westward expansion and the Dred Scott case. It remains the signature stop on any St. Louis itinerary, best planned around advance tram tickets and airport-style security screening.

Good to know
SafetyAll visitors pass through airport-style security (magnetometer/x-ray); no weapons, pepper spray, or fixed-blade knives are allowed (folding knives under 4 inches are OK). Arrive about 30 minutes before a booked tram time.
SafetyThe tram is a small capsule about 4 feet in diameter seating five people; it can feel cramped, hot, and shaky. Travelers prone to claustrophobia or motion sickness should weigh this before booking.
SeasonThe Riverfront Trail and parts of the underground Museum can flood or close during high water on the Mississippi River; check the NPS Alerts & Conditions page before visiting.
SeasonThe park is closed on Thanksgiving, Christmas, and New Year's Day, and Visitor Center hours vary seasonally (extended to 8pm on Fridays/Saturdays in summer); confirm current hours before you go.
RulesTram tickets should be booked online in advance — they routinely sell out same-day during peak season. Food is not allowed inside the museum galleries; only sealed water bottles are permitted.
MannersSpace is tight in both the tram and at the top observation deck, so keep bags small and be considerate about taking turns with other visitors.
CautionBuy tickets only through the official gatewayarch.com site; avoid street vendors or third-party resellers offering "discount" Arch tickets. Park only in official or reputable garages (e.g., the 200 S. Broadway garage) and don't leave valuables visible in your car.
Practical info
The Arch sits about 20-30 minutes by car from St. Louis Lambert International Airport (STL); reach it by rental car, rideshare, or downtown shuttle, with several paid parking garages nearby. Tram and museum admission pricing varies by season and age group, so check the official site for current rates and hours before your visit (verify latest details).
