25+ Free Things to Do in Washington, D.C. (Updated 2025)
"I found the Supreme Court to be very accessible: court sessions are open to the public on a first-come, first-served basis (held at 10am and 11am on Mon–Wed in two-week intervals from October–April), and the building offers free 30-minute educational lectures in the main hall, a visitor film, and special exhibitions even though there are no guided tours; check the court’s calendar on supremecourt.gov for exact session and lecture dates." - Matthew Kepnes
