The Jefferson National Expansion Memorial at the Gateway Arch and Museum of Westward Expansion will join hundreds of national parks nationwide in celebration of National Park Week from Saturday, April 20 through Sunday, April 28.

The fun will begin with a series of Fee Free Days from April 22 through April 26. On those days, the National Park Service will waive its park entrance fee.

At Jefferson National Expansion Memorial, a $3 park entrance fee is included in each adult “Journey to the Top” of the Arch ticket and/or movie ticket. During the Fee Free Days, all “Journey to the Top” of the Arch tram passes and/or movie tickets will be discounted by $3.

As always, admission to the Museum of Westward Expansion is free, and throughout National Park Week, area residents are invited to come explore the Museum and take advantage of a range of FREE programs, activities and films – all designed to help children and adults alike learn more about the national parks in their own backyards and those located well beyond their doorsteps.

The Gateway Arch and the Old Courthouse are part of Jefferson National Expansion Memorial, located on the riverfront in downtown St. Louis. The Old Courthouse is open daily from 8 a.m. to 4:30 p.m., with the exception of Thanksgiving, Christmas Day and New Year’s Day. The Arch’s Museum of Westward Expansion is open daily from 9 a.m. to 6 p.m., with the exception of Thanksgiving, Christmas Day and New Year’s Day. The Gateway Arch partners include the National Park Service; its cooperating association, Jefferson National Parks Association; and Metro Business Enterprises, which work together with their downtown neighbors to make the visitor experience even better.
