Do need to reserve a parking spot ?

Use Uber or Lyft. Easier to get around

Time slot reservations needed for visitor to enter museum. Print reservation or save image on your phone. Attendant reads code at entrance for quick entry without the wait. Found metered street parking during my visit within 5 minute walk of museum. Parking garages were within a 10 min walk of museum and reservation recommended.

I found a metered parking close by after circling inly a couple of times. I did use Lyft once.

There is only metered spots around the museum and no public parking garage for the National Mall. I used a Lyft.
