You'll get a text with your guide's info before the tour. We recommend Uber, Metro (Smithsonian or Federal Triangle stations), bus, or Capital Bikeshare/scooting to the meeting point, since parking's tricky nearby. We meet at the WWII Memorial Information Hut, look for your guide outside.
The tour ends at the Jefferson Memorial. From there, it's an easy ride on a Capital Bikeshare bike or rideshare, or a walk to the Wharf. The nearest Metro stops are L'Enfant Plaza and Smithsonian.
