Facility Overview

The St. George Garage is a central multi-story parking structure situated in the heart of the bustling National Harbor waterfront district in Oxon Hill, Maryland. Located at 251 Mariner Passage, this modern parking facility offers multi-level covered parking, shielding vehicles from seasonal weather conditions. Designed with spacious ramps, well-demarcated driving lanes, and clear signage throughout, the garage comfortably accommodates standard passenger sedans, compact cars, crossovers, and standard SUVs. Drivers of oversized pickup trucks or commercial high-roof conversion vans should pay close attention to the standard garage clearance threshold (approximately 6 feet 8 inches to 7 feet) posted at the entry portals, as higher-clearance vehicles may need to utilize open-air surface parking options nearby.

Visitor & Driver Tips

• Save Your Ticket or Pay via Mobile: Keep your entry ticket in a safe place or utilize the pay-by-phone QR code system upon return to expedite exit gate processing.
• Peak Arrival Hours: Weekend afternoons and festival evenings experience heavier inbound traffic along Mariner Passage and Fleet Street; plan to arrive 30 minutes early to secure preferred lower-level parking.
• Remember Your Level: Snap a quick photo of your parking column number and level indicator, as multi-level layouts can be deceptively uniform when returning late at night.
• Explore Alternate Exits: During major event egress, follow staff directions toward secondary exits to bypass congested waterfront choke points and quickly join the I-495 Beltway connector ramps.
