Cornerstone Tours

Cornerstone Tours runs small-group walking tours of Washington, DC, led by licensed DC guides. Tripadvisor ranks us #2 of 576 tours and activities in Washington, DC (September 2026), and guests have given us 369 reviews at a 4.95 average on Tripadvisor, GetYourGuide, Viator and Google, 356 of them five stars. On every Capitol Hill tour your Capitol entry is reserved before you arrive. We are not tip-based: our guides are paid, groups are capped between 10 and 15, and the history we tell holds up in front of a guest who knows the subject.

We run five public routes on a schedule. Capitol Hill has three options: the US Capitol with the Library of Congress, with the Supreme Court, or the BIG 3 inside all three. Arlington National Cemetery is a two-hour walk timed for the Changing of the Guard at the Tomb of the Unknown Soldier. Georgetown walks from the Old Stone House to the Exorcist Steps. The Lincoln assassination tour includes Ford's Theatre and Petersen House tickets. From November 2026, a 90-minute National Archives tour skips the public line in groups of up to six.

Every route also runs as a private tour on your date, in English, or in Italian, French or Spanish on request. For groups we build half-day, full-day and multi-day itineraries, with a private vehicle and driver when needed, and dedicated guides for school trips, corporate groups and conventions. Capitol Hill and Lincoln are wheelchair accessible. Public tours from $45.
