Two days around DC works best as a split, not a marathon: one day anchored on the National Mall, one full day across the Potomac in Old Town Alexandria, the easiest car-free day trip this city has. Currency is USD throughout, everything below runs on WMATA Metro or the seasonal water taxi, no rental car needed. Skip the DC Circulator entirely, it shut down for good on 31 December 2024, Metro and Metrobus absorbed its old routes.

Four days around DC works as two anchor days downtown plus two real day trips south, Mount Vernon on day three and Annapolis with the Naval Academy on day four. Currency is USD throughout. Days one and two run entirely on Metro and the seasonal Potomac water taxi, no car needed, but days three and four shift the math, Mount Vernon is easiest by car or tour bus, and Annapolis has no direct train at all, so a direct bus or a car is the realistic call.

Five days around DC stacks two anchor days downtown, Mount Vernon on day three, Annapolis and the Naval Academy on day four, then a genuinely different city, Baltimore, on day five. Currency is USD throughout. Days one and two run entirely on Metro and the seasonal Potomac water taxi, day three shifts to car or tour bus for Mount Vernon, day four needs a direct bus or car for Annapolis, and day five swaps all of that for a MARC or Amtrak ride out of Union Station.

Washington DC rewards a traveler who treats it as a launchpad, not just a checklist. This 6-day plan spends one day on the DC core and five days riding outward: Old Town Alexandria, Mount Vernon, Annapolis and the Naval Academy, Baltimore’s Inner Harbor, and the Great Falls gorge with an optional Harpers Ferry add-on. Four of those five legs run on Metro, a direct bus, or MARC/Amtrak. Great Falls does not, so plan on a car or a rideshare for that one day rather than assuming transit will get you there.

Seven days turns Washington DC into a genuine home base instead of just a city break! Day 1 anchors on the Mall, then six real day trips fan out: Alexandria, Mount Vernon, Annapolis, Baltimore, Great Falls, Harpers Ferry, and one long push to Gettysburg (swap in Shenandoah if you’d rather hike than tour a battlefield). Everything below runs in US dollars. Days 1, 2 and 5 run entirely on Metro, MARC and the seasonal Potomac water taxi.

Washington DC’s real advantage isn’t just the free Smithsonians, it’s the map: eight genuinely different day trips sit within roughly two hours, and knowing which ones are a straight Metro ride and which ones need a car or a once-a-day train is the difference between an easy week and a wasted morning at the wrong station. Alexandria and Baltimore are pure transit trips. Mount Vernon and Annapolis want a car, a bus, or a rideshare.

Washington DC’s museums are famous for being free, and that’s still true, mostly. In 2026 three of the biggest draws, the National Museum of African American History and Culture, the Air and Space Museum’s Mall building, and the National Zoo, now require a free timed-entry pass booked online, and showing up without one is the single most avoidable disappointment in the city. Two days covers the National Mall and one Smithsonian; four to five days is the real number for the museums, the monuments at night, and the Capitol without sprinting between them.

Washington DC runs on a genuinely rare deal: nineteen Smithsonian museums and the National Zoo, free, no ticket, no gate. The catch, and it’s a real one in 2026, is that three of the best, the African American history museum, the Air and Space Museum’s Mall building, and the Zoo itself, now require a free timed-entry pass booked ahead. Skip the pass and you skip the museum, that’s the whole deal.
