What Is the Address of Dulles Airport Parking Garage 1?

Dulles Airport Parking Garage 1 is located at 1 Saarinen Circle, Dulles, VA 20166 — which is the main address for Washington Dulles International Airport itself. The garage sits directly north of the Main Terminal building. When entering the airport via the Dulles Access Road or Dulles Toll Road (VA-267), follow signs for Parking Garages after the airport entrance. Garage 1 and Garage 2 share the same road approach; Garage 1 is the first structure you reach.

For GPS navigation, entering "Dulles Airport Parking Garage 1, Sterling, VA 20166" works well in most mapping apps. Some drivers find searching for "Dulles Airport Parking Garage" on Waze's live traffic map helpful, especially during peak travel times when the Dulles Access Road can back up. Construction activity related to the $7 billion Dulles Next capital improvement plan may affect approach roads in 2026 — check current conditions before you leave.

The garage is operated by the Metropolitan Washington Airports Authority (MWAA). For parking assistance — including lost vehicles, flat tires, or jump starts — call 703-572-4500, available 24 hours a day.

How Much Does Parking in Dulles Garage 1 Cost? (Rates & Fees)

Garage 1 charges $7 per hour with a daily maximum of $21 (verified April 2026, per flydulles.com parking information). There is no weekly rate cap — the $21 daily maximum applies each day of your stay. For a 7-night trip, expect to pay around $147 total in Garage 1.

Here's how Garage 1 stacks up against other on-airport options:

Garage 1 saves you $77 over 7 days compared to the Terminal Lot, with nearly identical terminal access. Pre-booking through reserve.flydulles.com can lock in your space and may offer lower reserved rates. All major credit cards and cash are accepted at the pay stations. For even deeper savings on longer trips, see our guide to Dulles Airport long-term parking rates and tips.

How Do You Get from Garage 1 to the Dulles Terminal?

Garage 1 connects to the Main Terminal via an underground pedestrian walkway — no shuttle required. The tunnel includes moving sidewalks for part of the route. Most travelers reach the terminal in roughly 5-10 minutes on foot. The same underground tunnel connects to the Silver Line Metro station, so you can also walk in from the Metro without going outside.

Follow the green To Terminal signs from any level of Garage 1. Elevators are available at multiple points for travelers with luggage, mobility aids, or strollers. Once inside the Main Terminal, all airline check-in counters and baggage claim are located here. From there, you proceed through TSA security screening — budget extra time for security queues, especially during morning peaks. Enrolling in TSA PreCheck can cut security wait times significantly at IAD.

After clearing security, AeroBus mobile lounges or the AeroTrain take you from the Main Terminal to Concourses A, B, C, D, and the new Concourse E (opening fall 2026 as part of the Dulles Next expansion). Plan for extra terminal transit time if your flight departs from a far concourse.

How Does the Free Garage Shuttle Bus Work at Dulles?

The free GARAGES shuttle bus runs 24 hours a day, 7 days a week between Garage 1, Garage 2, and the Main Terminal. Pick it up at Curb 2F inside the terminal, or from the designated shuttle stops in each garage. Look for buses labeled "GARAGES" — not the Economy bus.

The shuttle is a backup option. Most Garage 1 parkers use the underground walkway instead — it's usually faster than waiting for the next bus. The shuttle becomes more useful late at night or if you have heavy luggage and prefer not to walk the tunnel. Accessible buses are available for travelers who need them.

The ECONOMY shuttle (a separate bus) serves the Economy Lot only and departs from the same Curb 2F area. Don't confuse the two. If you're curious how the Economy Lot shuttle system works in detail, our article on the Dulles Airport economy parking bus covers it step by step.

How Do You Reserve a Spot in Dulles Garage 1 in Advance?

Reserving in advance is strongly recommended for busy travel periods. Book directly through reserve.flydulles.com, the official MWAA reservation portal. You'll receive a QR code that opens the entry gate when you arrive. The same code closes the exit gate when you leave — no ticket to lose.

Garage 1 holds 4,508 spaces, but during Thanksgiving, spring break, and summer weekends, levels fill up fast. An automated space-counting system at each level shows real-time availability as you drive in. However, if the garage is already full when you arrive unreserved, you'll need to pivot to Garage 2 or the Economy Lot. Pre-booking eliminates that risk entirely.

Note the 45-day vehicle registration rule: vehicles left in any on-airport lot for more than 45 days without registration must be reported. Call 703-572-4500 if you're planning an extended stay so MWAA can log your vehicle and prevent it from being flagged. For long trips, it's also worth comparing total costs against off-airport hotel parking — our Dulles Airport park and fly hotel guide shows options starting under $8/day with free shuttles.

What Are the EV Charging and Accessibility Options at Dulles Garage 1?

EV charging stations are available at Dulles Airport parking facilities, including Garage 1, per the official IAD EV charging information page. Charger details — including exact station count, charger types (Level 2 vs. DC fast charge), and per-session pricing — are listed on that page and may be updated as the airport's 100 MW Solar Power Facility (currently under construction) expands the charging infrastructure. Check before your trip if EV charging is a deciding factor.

ADA-accessible parking spaces are available on multiple levels of Garage 1. Elevators serve all levels and connect to the underground walkway. Call boxes are located throughout the garage for emergency assistance. If you need help locating your vehicle, changing a flat, or getting a jump start, call the 24-hour parking assistance line at 703-572-4500. All shuttle buses are accessible for travelers using wheelchairs or mobility devices.

How Does Dulles Garage 1 Compare to Garage 2 and Economy Lots?

Garage 1 and Garage 2 share the same daily rate of $21/day, but their terminal connections differ. Garage 1 uses the underground walkway with moving sidewalks — the same tunnel that connects to the Silver Line Metro. Garage 2 uses a covered pedestrian walkway and is described by MWAA as most convenient for international departures (Concourse A airlines include British Airways, Lufthansa, Emirates, and others).

Here's a quick side-by-side comparison:

• Garage 1 vs. Garage 2: Same price ($21/day). Garage 1 connects via underground tunnel with moving sidewalks. Garage 2 connects via covered walkway — preferred if you're flying internationally from Concourse A.
• Garage 1 vs. Economy Lot: Garage 1 costs $6/day more ($21 vs. $15), but you walk to the terminal instead of waiting for a shuttle. Better for early morning or red-eye flights when shuttle frequency may be lower.
• Garage 1 vs. Off-Airport Hotels: Off-site lots like Comfort Suites Chantilly start at just $5.99/day. That's a saving of over $100 on a 7-day trip compared to Garage 1. Trade-off: you add a shuttle ride of 6-15 minutes each way.
• Garage 1 vs. Terminal Lot: Terminal Lot costs $32/day — 52% more expensive than Garage 1. Both use underground walkways. The Terminal Lot is marginally closer, but Garage 1's price advantage is hard to justify skipping.

Tips for First-Time Parkers at Dulles Garage 1

A few practical tips will save you time and stress on travel day:

1. Take a photo of your parking level and space number. Garage 1 has multiple levels and thousands of spaces. You'll thank yourself when you return after a long trip.
2. Use the underground walkway. Skip the shuttle — the tunnel with moving sidewalks is almost always faster, especially with luggage.
3. Book in advance for holiday travel. Memorial Day weekend, July 4th, and Thanksgiving are especially busy. The garage fills up, and pre-booking guarantees your spot.
4. Budget 20-30 minutes from car to gate. Allow 5-10 minutes to walk to the terminal, then time for check-in and TSA security screening, plus the Aerobus or AeroTrain ride to your concourse.
5. Check construction updates before you go. The Dulles Next project is active in 2026. Signage near the garage may change. Monitor the Dulles Next construction page for any road or access updates.
6. Compare off-airport options first. If you're staying 5+ days, off-site lots can save $75 or more. Search IAD parking on Triply to compare Garage 1 against off-airport lots before you decide.

Parking at IAD doesn't need to be complicated. Garage 1 is a reliable, mid-priced option with direct terminal access. Know the address, book ahead when you can, and you'll be checked in and through security without a hitch. Compare all IAD parking options on Triply — from $5.99/day off-site to $21/day in Garage 1 — and lock in your rate before your trip.
