Washington, D.C., is not a cheap city. A hotel room can easily become the largest expense of a trip, and even getting around carries a price. But for someone traveling alone, the nation’s capital has one unusual advantage: many of its biggest attractions cost nothing to enter.

Washington welcomed 27.2 million visitors in 2025, marking a third consecutive year of growth, according to Destination DC, the city’s official tourism organization. Visitors spent a record $11.9 billion, supporting more than 114,000 jobs and generating $2.4 billion in tax revenue.

For a solo traveler trying to control costs, however, the more useful number may be 17.

Seventeen museums and a zoo

The Smithsonian operates 21 museums and the National Zoo, with 17 museums and the zoo located in the Washington area. Eleven of those museums sit on the National Mall, allowing a visitor to move between major attractions on foot rather than paying for transportation between each stop.

Admission is free at Smithsonian museums in Washington. That includes the National Museum of Natural History, the National Museum of American History, the National Air and Space Museum and the National Museum of African American History and Culture.

Free does not always mean walk in whenever you want. The National Air and Space Museum and National Museum of African American History and Culture currently require free timed-entry passes. The National Zoo also requires a free entry pass.

For a solo trip, reserving those passes before booking out the day can prevent a free attraction from becoming an unavailable one.

Where the trip stops being cheap

Lodging is the obvious counterweight to all those free museums.

Washington’s average daily hotel room rate was $265.82 in 2025, according to Destination DC data. The tourism organization also says hotel occupancy and average daily rates tend to peak from March through June and again from September through October. 

Metro is cheaper, but not free. Metrorail currently costs between $2.25 and $6.75 for a one-way trip, depending on the route, day and time. Weekend and late-evening fares generally range from $2.25 to $2.50. Riders can pay with SmarTrip or a contactless credit or debit card. 

That makes Washington less a cheap destination than a city where one major part of the travel budget can be stripped away. A traveler may still spend heavily on a room, meals and transportation, but an entire day of museums can cost nothing.

The free options extend beyond the Smithsonian

The Smithsonian is only part of Washington’s no-admission landscape. The National Gallery of Art, which is not part of the Smithsonian, also charges no admission and requires no ticket for its galleries, exhibitions or guided tours. It is open daily from 10 a.m. to 5 p.m.

Across the National Mall, the National Park Service charges no entrance fee for the Lincoln Memorial, Martin Luther King Jr. Memorial, Vietnam Veterans Memorial, Korean War Veterans Memorial and other sites it manages. Most of the outdoor memorials can be visited 24 hours a day, allowing a solo traveler to continue sightseeing after the museums have closed.

Two other major attractions are also free but require more planning. Tours of the U.S. Capitol cost nothing, although reservations are recommended. The approximately hour-long tour includes the Rotunda, National Statuary Hall and the Crypt.

The Library of Congress also requires a free timed-entry ticket for its Thomas Jefferson Building. Tickets can be reserved up to 30 days ahead, with additional same-day tickets released online at 9 a.m. Eastern Time.

Timing matters

The busiest and most expensive periods are not always the best choice for a traveler focused on cost.

Washington’s famous cherry blossom season brings heavy spring demand, while the week surrounding July 4 also draws large crowds. Travelers whose priority is museums rather than seasonal events have more flexibility to choose quieter dates.

The city’s international appeal also extends well beyond North America. Destination DC lists China as Washington’s fifth-largest international visitor market in 2025, behind Canada, India, the United Kingdom and Germany. 

For someone traveling alone, the practical advantage remains concentrated around the National Mall. Eleven Smithsonian museums are clustered there, most require no reservation, and none charges admission.
