Smithsonian museums are amazing for many reasons—not least of which is the fact that entrance to all of them is free. In honor of this perk, Smithsonian Magazine sponsors the annual Museum Day Live!, when more than 1,500 museums across the country do away with admission fees for one day. This year’s event—the 10th anniversary—takes place September 27.

Search by zip code and use this handy map to find participating cultural centers—which include everything from prominent art institutions (the de Young museum in San Francisco) to lesser-known gems (National Museum of Civil War Medicine in Frederick, Maryland). You can even search by term; “auto” turns up 10 antique-filled museums.

Register online for a ticket, which is good for two people—and only one per household. Added bonus: a free one-year digital subscription to Smithsonian magazine.
