St. Louis

World-class culture, free

A zoo, art museum, science center and more — admission: $0.

The single most distinctive feature of life in St. Louis is the Zoo-Museum District (ZMD), a property-tax-funded system that makes five major institutions free every day for everyone. The Saint Louis Zoo (home to 12,500+ animals across 400+ species), the Saint Louis Art Museum (perched on Art Hill in Forest Park), the Saint Louis Science Center (700+ hands-on exhibits), the Missouri History Museum (featuring the 1904 World's Fair exhibit), and the museum under the Gateway Arch all charge zero general admission.

The 2025 combined ZMD tax rate was just under 22 cents per $100 of assessed valuation, generating over $86 million annually for the five institutions.

Forest Park, at 1,326 acres, is roughly 500 acres larger than New York's Central Park and houses three of the free ZMD institutions within its boundaries, plus 30+ miles of trails, nature reserves, golf courses, boating, and the Muny outdoor theater. City of St. Louis · Wikipedia

The Missouri Botanical Garden — widely considered one of the top botanical gardens in the U.S. — is free for city and county residents on Wednesday and Saturday mornings, though blackout dates apply during major festivals. Its 14-acre Japanese strolling garden is one of the largest in North America. Missouri Botanical Garden · Mental Floss

The Gateway Arch grounds, visitor center, and museum are always free. You only pay if you want the tram ride to the top or the documentary film. The Arch is 630 feet tall, making it the tallest monument in the United States and the tallest arch in the world. However, the Arch was built on land cleared by demolishing nearly 40 square blocks of a historic African American community and waterfront business district — and its 1935 bond election was later exposed as fraudulent by a Pulitzer Prize-winning investigation.

Caveats: "Free" doesn't mean everything is free. Parking at the Zoo and Science Center costs money ($12–$15 at the Science Center). Special exhibits, IMAX films, planetarium shows, and the Arch tram all carry fees.
