Cheap Night Tours in Washington, DC

Memorials by Moonlight

• Washington Walks operates Memorials by Moonlight, a three-hour tour that starts at 6:30 p.m. almost every night between Memorial Day and Labor Day. This tour stops at many of the major memorials, including the Thomas Jefferson Memorial, the Korean War Veterans Memorial, the Abraham Lincoln Memorial and the Vietnam Veteran's Memorial. As you approach each memorial, a guide tells its story. You then have time to look around by yourself. Tours run rain or shine, and leave from the Thomas Jefferson Memorial's accessible entrance sign. Most routes are wheelchair-accessible. In 2010, this tour was free and ran through Labor Day. No reservations are necessary. All you need to do is show up. Groups of 25 or more should call in advance.
