Plan your tour in advance, as tours can book quickly. Determine a day or two that will work for you before contacting a tour organizer. Tours are free.
Reserve spots for you, your family or small group (15 people or fewer) by contacting your U.S. Representative or Senator. You can also book a tour online via the U.S. Capitol Visitor Center.
Reserve a large group (more than 15 people) tour online through the U.S. Capitol Visitor Center. Do not contact your Congressperson to reserve a large group tour.
Enjoy the Capitol grounds and U.S. Capitol Visitor Center before or after your tour. You don't need a guide or reservations to explore these areas.
