United States 4 Day Itinerary

New York to Washington DC to Las Vegas to San Francisco in four days is not an itinerary, it is a description of the entire continental United States compressed into a length of time that makes it impossible. Washington DC to San Francisco alone is a nearly six hour flight covering three time zones, and stacking that onto a New York morning and a Vegas afternoon ignores security lines, baggage, delays, and the basic fact that a body cannot process three time zone shifts in ninety-six hours and still enjoy any of it. Pick one region. Here is what four days actually gets you if you stay on the East Coast, the version of this trip people can genuinely execute.

Day 1: New York City

Book Statue of Liberty crown tickets before anything else on this list, they sell out three to four months ahead for peak season and are non-transferable once purchased, with your exact name checked against ID at the door. If you missed that window, the pedestal and grounds ticket is a same-week booking and still gets you close to Lady Liberty and onto Ellis Island’s immigration museum, which is arguably the more moving stop of the two anyway.

Spend the afternoon working uptown: Times Square for the sensory overload, Central Park for a break from it, and either the Empire State Building or Top of the Rock at Rockefeller Center for the skyline view, pick one rather than both since they show largely the same city from a similar height at a premium price each. Grab same-day rush or lottery tickets for a Broadway show if your budget does not stretch to a full-price seat booked weeks out. Get a MetroCard or tap a contactless card directly at the subway turnstile, most stations now accept OMNY tap payment without needing the physical card at all, and tip 18 to 20 percent at sit-down restaurants since it is the default expectation, not a bonus.

Day 2: Washington DC

The Amtrak Acela from New York to DC takes about three hours and drops you at Union Station, close to the National Mall and considerably less stressful than flying a route this short. The Smithsonian museums are free, a genuine rarity for a world capital’s flagship collections, and the National Air and Space Museum plus the National Museum of African American History and Culture are worth prioritizing since both draw long timed-entry queues by midday. Walk the Mall from the Capitol to the Lincoln Memorial as the day cools into evening, when the Lincoln and Martin Luther King Jr. memorials are lit and noticeably less crowded than at midday.

DC’s metro is efficient and the city center is genuinely walkable, so skip renting a car entirely, parking downtown is expensive and finding it eats time you do not have on a one-day stop.

Day 3: Philadelphia or Baltimore, your call

Rather than attempting a coast-to-coast leap, use day three for a short rail hop instead. Philadelphia sits about ninety minutes from DC by train and delivers the Liberty Bell, Independence Hall, and a genuinely good food scene without the hype-driven wait times of the bigger cities. Baltimore, closer still, offers the Inner Harbor and a more low-key day if you would rather slow down after two dense city days. Either choice keeps you within the same time zone and the same rail network, which is the entire point of a four day trip: fewer transitions, more actual time on the ground.

Day 4: Return and departure

Head back to New York or fly out of a DC-area airport depending on your original entry point, and build real buffer time into your last transit day, Northeast Corridor trains and East Coast airports both run tight schedules that do not forgive a missed connection gracefully.

Visa and entry notes

Most Visa Waiver Program travelers, including UK, EU, Australian, and several dozen other nationalities, need an approved ESTA rather than a full visa, and the ESTA fee rose to just over 40 dollars as of January 2026 following a hike from the previous 21 dollar rate. Apply as soon as you have booked flights and no later than 72 hours before departure, though same-day approval is common. If your passport is not machine readable or lacks an embedded chip, you do not qualify for the waiver and will need a full B1/B2 visitor visa through your nearest US embassy instead, a process that can take weeks depending on your country and current appointment backlogs.

One honest closing thought: the American West deserves its own dedicated trip. Las Vegas, the Grand Canyon, and San Francisco are extraordinary, but bolting them onto an East Coast four-dayer only guarantees you experience all of it exhausted and none of it well.
