About this adventure

Buried beneath the soaring 630-foot stainless steel Gateway Arch along the Downtown St. Louis riverfront, the Museum at the Gateway Arch is an expansive, subterranean cultural museum that underwent a massive $380 million modern expansion. Admission to the museum galleries is completely free, making it an extraordinary, climate-controlled destination for winter days. Six interactive themed exhibit galleries trace over two centuries of westward expansion, river trade, and Indigenous Mississippian history through hands-on discovery stations, life-sized buffalo and covered wagon replicas, and interactive touchscreens. The museum is universally accessible via sweeping ADA ramps and elevators, with family restrooms with diaper changing stations, quiet nursing mother lounges, and airport-style security at the glass entrance pavilion.
