  • North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
  • North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
  • North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
  • United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
  • United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
  • United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
  • United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Chantilly is a Dulles-corridor suburb in Fairfax County, Virginia, not a sightseeing town. Its one heavyweight draw is the Smithsonian's Steven F. Udvar-Hazy Center — free entry, paid parking, a 15-minute drive from the airport. Everything else is parks, a Civil War battlefield and strip-mall dining, so you need a car and a reason to be here.

Arrive & move

Airports are listed under At a glance; this is how to move once you are in

Getting around

A car is the practical choice: sights sit 5–15 min apart along Route 28 and US-50, and pavements are patchy. Without a car, Fairfax Connector buses cover the basics — 983 to the Udvar-Hazy Center and Dulles Airport, 650 toward the Vienna/Fairfax-GMU Metro station, 901 to the Silver Line at Herndon. Rideshare is easy but surge-priced at airport peaks.

Eat & sleep

Which area to sleep in

Where to sleep

Areas, not hotels: pick the one that fits your arrival time and plans.

Dulles/Route 28 corridor (Corsair Ct, Centerview Dr, Westfax Dr)

Airport hotels with free shuttles; best for one night or a layover.

Metrotech Dr / Chantilly Crossing

Walkable cluster of chain hotels, groceries and fast food; the most practical base without a car.

Westfields (Conference Center Dr)

Business-hotel and conference zone; quiet at weekends, needs a car for everything.

Watch out

Safety

A low-crime, well-lit suburb; the real risks are traffic on Route 28 and US-50, deer on back roads at dusk, and summer heat on exposed trails. Standard US city precautions apply.
  • Almost nothing is walkable between clusters; plan each hop by car, bus or rideshare.
  • Udvar-Hazy parking is paid per vehicle and the lot fills on weekend afternoons — arrive at opening.
  • The museum is free but the IMAX theatre and some simulators are ticketed separately.
  • Summer afternoons bring thunderstorms and heavy Beltway/Dulles Toll Road traffic; build in slack before a flight.
