Nineteen Smithsonian museums charge nothing, and two major D.C. institutions are marking milestones this season. Almost none of this costs a dollar. The foundation of any budget trip to Washington. The Smithsonian operates museums and a zoo across the city and admission is free at all of them, with no general entry charge. Most visitors underestimate how much this saves over three or four days.
Book Air And Space
One important exception to the walk-in rule. The National Air and Space Museum on the National Mall requires free timed-entry passes, which must be reserved in advance and do run out during busy periods. Book before you travel.
The Hirshhorn Garden Reopens
The Hirshhorn Sculpture Garden reopens on October 31 after a four-year transformation, displaying close to 60 sculptures among nearly 30,000 newly planted trees and plants. A brand-new free attraction opening mid-fall is unusual timing in Washington.
America’s 250th
Smithsonian museums are running Our Shared Future: 250 across 2026 for the country’s semiquincentennial, with exhibitions and public programs on American history and democracy spread across multiple institutions. All of it is included in free admission.
The National Zoo
Free, open year-round, and considerably more pleasant in October than in August humidity. Entry passes are typically required, they cost nothing, and the walk through Rock Creek Park to reach it is part of the appeal.
The Monuments At Night
The memorials on and around the National Mall are open 24 hours and staffed into the evening. Lincoln, Vietnam Veterans, Korean War and Martin Luther King Jr. are all dramatically better after dark and far less crowded.
The National Gallery
Not a Smithsonian museum and free regardless, with one of the strongest collections in the country and the only Leonardo da Vinci painting in the Americas. The Sculpture Garden alongside it is free to walk through.
The Library Of Congress
The Thomas Jefferson Building is among the most spectacular interiors in Washington and free to enter, though timed passes are generally needed. The Main Reading Room views are the reason to go.
Rock Creek Park
More than 1,700 acres of urban national park running through the middle of the city, free, and at its best in mid to late October when the foliage turns. It is the piece of Washington most visitors never see.
