Where Is Dulles Airport Parking Garage 2 and How Do You Get There?

Garage 2 sits on the south side of the Main Terminal, just off Copilot Way, Sterling, VA 20166. It is one of the two main on-airport parking garages operated by MWAA at IAD.

To drive to Garage 2, follow the signs from the main airport access roads. The primary route from the DC area uses the Dulles Access Road (free, airport-only) or the Dulles Toll Road (VA-267). From the south, take VA-28 (Sully Road) or US-50 (Lee Jackson Memorial Highway). Once on airport property, follow overhead signs marked "Garage 2" — the garage is clearly signposted from both the arrivals and departures roadways.

Before you leave home, check real-time traffic on Waze — the Dulles corridor can back up on VA-28 and the Toll Road during peak hours. Budget extra time if your flight is early morning or evening rush.

The GPS coordinates for Garage 2 are 38.9544261, -77.4524618. You can also use the official IAD interactive parking map to preview the layout and confirm your route before arriving.

What Does Dulles Parking Garage 2 Cost? Rates, Fees, and How to Save

Garage 2 charges $7 per hour with a $25 daily maximum, based on the airport's drive-up rates (verified October 2026). Three hours costs $21, and the $25 cap applies from the fourth hour, so the daily maximum is what you pay on most multi-day trips.

For a 5-day trip, Garage 2 costs $125 total at the daily maximum. The Hyatt Regency Dulles Airport, sold on Triply, is about $10/day, roughly 62% less per day than Garage 2 (about $67 for 7 days versus $175), though it has a 4-day minimum booking. The DoubleTree Washington Dulles Airport is about $26/day, slightly more than Garage 2, so it suits travelers who want its shuttle or room for a large vehicle rather than a lower price. If budget matters more than walking convenience, see our full breakdown of Dulles long-term parking rates and best lots.

Dulles Garage 2 Map: Layout, Levels, and How to Find Your Car

Garage 2 is a multi-level structure with a total capacity of 3,727 spaces, making it the second-largest on-airport garage after Garage 1 (4,508 spaces), per MWAA capacity data. Here is what to know about navigating each level.

Level-by-Level Overview

• Entry level (Level 1): Ticket dispensers and entry lanes are located here. This is also where you will find the exit payment kiosks. Note your level and row letter or number immediately after parking.
• Upper levels: Standard self-park spaces. The automated space-counting system displays real-time available spots on overhead signs at each level entrance — green numbers mean spaces are open, red or zero means that level is full.
• Walkway connection level: The covered pedestrian walkway to the Main Terminal connects from a specific level — follow the "To Terminal" overhead signs from the moment you park. This is the fastest path to check-in and baggage claim.
• Accessible/ADA spaces: Designated accessible parking spaces are available on multiple levels, typically near elevator banks and the terminal walkway access point. Look for blue ADA signage near the elevator cores.

To avoid losing your car, take a photo of the level number and row letter before walking to the terminal. The garage uses a standard alphanumeric system — for example, Level 3, Row C. The IAD interactive map also shows the garage layout and the walkway connection point.

How Does the Automated Space-Counting System Work?

The automated space-counting system is a real-time display at each level entrance showing how many open spots remain. The system uses sensors above each stall. A green number means spaces are available. A red display or "0" means the level is full — proceed to the next level. During peak travel periods (summer, holiday weekends, major international departures), upper levels fill fastest. Arriving early in the morning typically gives you the best choice of spots near the walkway.

How Do You Walk from Garage 2 to the Dulles Terminal?

Garage 2 connects to the Main Terminal via a covered pedestrian walkway — no outdoor exposure and no shuttle required. This is the key advantage Garage 2 has over the Economy Lot, and it is one reason MWAA describes it as the most convenient option for international destinations.

Follow the "To Terminal" signs from your parking level to the walkway entrance. The walk brings you directly into the Main Terminal, where all ticketing and baggage claim are located. From the Main Terminal, you proceed through security and board the AeroTrain or mobile lounges to your concourse.

Here is a step-by-step path from your car to your gate:

1. Park and note your level and row (take a photo)
2. Follow "To Terminal" signs to the covered pedestrian walkway
3. Walk through the walkway into the Main Terminal (ticketing and baggage claim level)
4. Check in at your airline's counter or proceed to security
5. Clear TSA security screening — consider TSA PreCheck to save time at the checkpoint
6. Board the AeroTrain or mobile lounge to your concourse (A for international, B for domestic, C/D for United)

If you are flying on an international carrier — Air France, Lufthansa, British Airways, Emirates, or others in Concourse A — Garage 2 is your best on-airport parking choice. The walkway puts you steps from Concourse A check-in counters.

Is Garage 2 the Best Parking Option for International Flights at Dulles?

For most international travelers, yes — Garage 2 is the strongest on-airport choice. Its covered walkway connects directly to the Main Terminal, which is where all international carriers handle ticketing. You bypass the shuttle wait that Economy Lot users face.

All international airlines at IAD operate out of Concourse A: Air France, ANA, Austrian Airlines, British Airways, Emirates, Ethiopian Airlines, Etihad, KLM, Lufthansa, Qatar Airways, Royal Air Maroc, SAS, TAP Air Portugal, Turkish Airlines, and Virgin Atlantic. Every one of those flights checks in at the Main Terminal — a short walk from Garage 2.

IAD is the Washington region's primary international airport, serving all long-haul international routes. With Concourse E opening in fall 2026 (adding 14 new United gates and a 40,000 sq ft United Club), terminal traffic will increase. Booking Garage 2 in advance before major travel periods is smart planning. If you are flying United on a domestic or connecting international itinerary, check our guide to Dulles parking for United Airlines flights for concourse-specific tips.

Does Dulles Garage 2 Have EV Charging, Accessible Parking, or Other Amenities?

Yes — Garage 2 includes EV charging stations, ADA-accessible spaces, and 24-hour parking assistance. Here is what the garage offers beyond standard parking.

EV Charging in Garage 2

Electric vehicle charging stations are available within the IAD on-airport EV charging network. Garage 2 has 10 chargers on Level 1 (2 of them at handicap spaces) and 56 on Level 3, and the Level 3 units are 120V. There is no extra fee beyond regular parking rates, and charging is first come, first served. Check the interactive parking map for charger locations before you arrive, or call MWAA at 703-572-4500.

Accessible and ADA Parking

Designated ADA-accessible spaces are located on multiple levels of Garage 2, near elevator banks and the terminal walkway entrance. Blue signage marks accessible stalls. Travelers needing accessible parking assistance can call MWAA's 24-hour parking line at 703-572-4500 for flat tires, jump starts, or help locating your vehicle.

Other Amenities and Policies

• Payment: All major credit cards and cash accepted at exit kiosks
• Pre-booking: Available at reserve.flydulles.com for guaranteed space
• Long-stay policy: Vehicles left beyond 45 days may be subject to towing — contact MWAA in advance for extended stays
• 24-hour assistance: Call 703-572-4500 for lost vehicles, flat tires, or jump starts
• Security: The garage is staffed and monitored as part of the IAD on-airport campus

How Does the Dulles Garage 2 Shuttle Service Work?

Garage 2 does not require a shuttle — the covered pedestrian walkway is the primary connection to the terminal. However, a free 24/7 shuttle is available for all on-airport garages if you need it or if the walkway is temporarily closed for maintenance.

The shuttle picks up and drops off at Curb 2F on the terminal departures level. Look for buses marked "GARAGES". The same shuttle system also serves the Economy Lot (look for buses marked "ECONOMY"). For most Garage 2 users, the walkway is faster and more convenient than waiting for the shuttle. If you are traveling with heavy bags or mobility challenges, the shuttle is a solid backup.

If your trip is long-haul and you want an off-site lot, note that shuttle hours differ. The Hyatt Regency Dulles Airport shuttle runs 24/7 (every 30 minutes from 6 AM to 11 PM, on demand overnight), while the DoubleTree Washington Dulles Airport shuttle runs every 30 minutes from 4 AM to midnight with no service from midnight to 4 AM.

Dulles Garage 2 vs. Garage 1 vs. Economy Lots: Which Should You Choose?

The right lot depends on your budget, how long you are parking, and how quickly you need to reach the terminal. Here is a direct comparison of every on-airport option.

Garage 1 is the direct sibling to Garage 2 — same daily rate, similar walkway access, but with the added bonus of connecting to the Silver Line Metro station via the underground tunnel. If you plan to ride the Metro to IAD on your return, Garage 1 may be the better pick. For a detailed look at reserving Garage 1 specifically, see our Dulles Airport Parking Garage 1 reservation guide.

The Economy Lot at $20/day is the cheapest on-airport option, $5/day less than Garage 2. For a 7-day trip, that is $35 in savings. The trade-off is a shuttle ride instead of a walkway. For most short trips of 1-3 days, Garage 2 is worth the price for the direct access. For trips of 4 days or more, the Hyatt Regency Dulles Airport at about $10/day undercuts every on-airport option (it has a 4-day minimum). The DoubleTree Washington Dulles Airport, at about $26/day, costs more than both the Economy Lot and Garage 2.

Tip: During peak summer and holiday travel, Garage 2 fills quickly. Use the automated space-counting displays as you enter — if Level 1 shows zero available, proceed to the next level without slowing down. Pre-booking via reserve.flydulles.com guarantees your space regardless of walk-up demand.

Ready to Find the Best IAD Parking Rate?

The Dulles Airport Parking Garage 2 map shows a well-located structure with direct terminal access at $25/day, a solid middle ground between the pricier Terminal Lot and the shuttle-dependent Economy Lot. For international travelers especially, the covered walkway saves time and hassle every single trip.

That said, if you are parking for 4 days or more, the Hyatt Regency Dulles Airport can cut your costs: it is about $10/day, roughly 62% less than Garage 2's $25/day. The DoubleTree Washington Dulles Airport is about $26/day, slightly more than Garage 2, so it is a choice for its shuttle and large-vehicle room, not for price. Compare off-site IAD parking on Triply and find the best fit for your trip before you fly.
