A Weekend Beyond Washington DC
Two days is barely enough for the marble-and-museums version of Washington DC, so this plan treats the city as a launchpad instead: one deliberately light day on the Mall, then a full escape across the Potomac to Old Town Alexandria’s cobblestone waterfront. Everything runs in USD, and this particular pairing is DC’s only genuinely car-free weekend, no rental, no tour bus, just Metro, your feet, and a seasonal water taxi if you time it right.
This is the shortest rung on a longer day-trip ladder: add a day and the 3-day version keeps this exact Day 1 and Day 2, then adds Mount Vernon; the 4-day plan works in Annapolis and the Naval Academy; the 7-day version climbs all the way to Great Falls and one long add-on. For the full day-trip roster and a cost comparison across all of them, see the DC day trips guide .
Book these before you go
- A DC hotel near a Metro line : pick Blue or Yellow for the fastest Alexandria run
- International Spy Museum tickets : timed entry, priced dynamically, cheaper booked a few days out
- An Old Town Alexandria walking or food tour : handy if you’d rather not self-navigate the cobblestones
| Day | Focus | Travel time | Rough daily cost |
|---|---|---|---|
| 1 | DC anchor: an odd-hours pass through the Mall | none (in the city) | ~$40-60 |
| 2 | Old Town Alexandria: cobblestones and a river crossing | ~25 min Metro or ~30 min seasonal water taxi | ~$35-55 |
Day 1: An anchor, not a checklist
Skip the sprint through fifteen monuments and pick three, then walk the same short loop twice: once at midday to get oriented, once after dark, when the Lincoln, the WWII Memorial, and the MLK Memorial are unticketed, unstaffed, and lit differently enough to feel like a second visit rather than a repeat. If a Smithsonian on your list needs a free timed pass (NMAAHC, the Air and Space Museum’s Mall building, or the Zoo), book it directly on si.edu before you fly, not through a paid reseller charging for something that costs nothing. For an odder afternoon than another museum hall, the International Spy Museum runs on dynamic, timed pricing and rewards booking a few days ahead. One planning note: the old DC Circulator bus stopped running for good on 31 December 2024, so double-check current routes at washington.org rather than trusting an older guide.
Day 2: Old Town Alexandria, without a car
Cross the Potomac on the Blue or Yellow Line to King St-Old Town, about 25 minutes from downtown, then let the free King Street Trolley carry you the rest of the way to the waterfront if the walk feels long. The reward is a genuinely walkable grid of cobblestoned colonial-era streets, small shops, and a working river view that has nothing to do with marble monuments, with lunch somewhere casual running $12-20 before an 18-20% tip. Between March and December, swap the train for the Potomac water taxi from The Wharf instead, about $22 one-way for a 30-minute crossing with a better view than any train window offers; check Visit Alexandria for the current trolley and taxi schedule before you build the day around either.
Is Old Town Alexandria worth a full day trip from DC?
Yes, and it earns the trip on its own terms rather than as a Mall add-on: cobblestone streets, colonial-era rowhouses, and a working waterfront with no marble in sight. Budget a half day at minimum, a full one for two meals there. It’s the single easiest, most transit-friendly day trip DC offers, no rental car required.
Do you need a car for this weekend?
No, and that’s what makes this particular two-day plan unusual among DC’s day trips: both the anchor day and Alexandria run entirely on Metro, the seasonal water taxi, or your own feet. Add a third day for Mount Vernon and a car, or a tour bus, becomes necessary; for just these two days, skip the rental altogether.
When does the Potomac water taxi actually run?
Only March through December; it’s a warm-season service tied to river conditions, not a year-round schedule. If you’re visiting in January or February, don’t build Day 2 around it, take the Blue or Yellow Line to King St-Old Town instead, which runs on the same schedule all year regardless of season.
Before you go
Bring a physical or mobile SmarTrip either way; contactless bank cards and phone wallets now tap directly at Metrorail faregates, so hunting for a farecard machine isn’t mandatory just to cross the river on Day 2. Tap out as well as in: weekday rail fares are distance-based up to a $6.75 maximum, and skipping the tap-out at exit charges you that maximum automatically. Weekend and late-night trips flatten to roughly $2.25-2.50 instead, the cheapest way to ride all weekend.
