Facility Overview

The Great Falls Parking Facility at Great Falls Tavern serves as the primary gateway to the Maryland side of the Chesapeake and Ohio Canal National Historical Park (C&O Canal) and the iconic Billy Goat Trail. Situated at the western terminus of MacArthur Boulevard in affluent Potomac, Maryland, this expansive open-air surface parking facility accommodates outdoor enthusiasts, hikers, cyclists, and history buffs. The lot is paved, organized into clearly marked angled and perpendicular stalls, and features dedicated lanes for standard passenger cars alongside oversized stalls designed for passenger vans, recreation vehicles (RVs), and school buses.

Because it is a ground-level, open-sky lot with no overhead barriers or parking decks, there are no vertical clearance restrictions in the general parking rows. This makes the facility exceptionally well-suited for high-profile vehicles, including lifted pickup trucks, full-size SUVs, vans equipped with rooftop kayak carriers or cargo boxes, and vehicles towing light bike racks. Wide turning radii and straightforward circulation loops allow larger vehicles to maneuver comfortably during normal traffic volumes.

Prime Location & Nearby Attractions

The facility provides immediate, steps-away access to some of the Capital Region's most celebrated outdoor and historical treasures:

• Historic Great Falls Tavern & Visitor Center: Located less than a 2-minute walk from the parking bays, this 1828 landmark showcases canal history, interpretive exhibits, and departures for the Charles F. Mercer replica canal boat.
• Great Falls Overlook & Olmsted Island: A 10-minute stroll across the accessible boardwalk brings visitors to dramatic panoramic vistas of the Potomac River thundering through the Great Falls cataract.
• Billy Goat Trail (Section A): The trailhead for this world-famous 1.75-mile technical rock scramble across the rugged cliffs of Mather Gorge begins just south along the towpath, roughly 0.3 miles from the parking lot.
• C&O Canal Towpath (Mile Marker 14.4): A flat, crushed-stone route spanning 184.5 miles from Georgetown to Cumberland, Maryland, ideal for running, gravel biking, and leisurely walking.
• Maryland Gold Mine Trail: Located approximately 0.2 miles northeast, offering wooded loops past the remnants of 19th-century gold prospecting shafts.
• Potomac Village: Located roughly 3.5 miles (a 7-minute drive) north along Falls Road (MD-189), featuring premier neighborhood dining, delis, and coffee shops like The Hunter's Hound, Potomac Grocer, and Mitch & Bill's.

Access, Navigation & Transit Connectivity

Vehicle access to the facility is straightforward via MacArthur Boulevard, which dead-ends directly into the park's entrance station kiosk. Drivers traveling from Washington, D.C., Northern Virginia, or suburban Maryland typically connect via Interstate 495 (the Capital Beltway), exiting at Clara Barton Parkway (Exit 41) or River Road / MD-190 (Exit 39) before heading west toward Potomac and descending onto MacArthur Boulevard.

While public transit does not run directly to the park gate, Ride On Bus Route 36 serves nearby Potomac Village, and the closest Washington Metro rail connection is the Grosvenor-Strathmore or Bethesda Station on the Red Line (approximately 15 to 20 minutes away by rideshare or taxi). On weekends and holidays with favorable weather, MacArthur Boulevard frequently experiences heavy queueing as visitors wait for gate entry; leaving the park during peak afternoon hours can involve brief delays as outbound traffic merges back toward Clara Barton Parkway and Falls Road.

Visitor & Driver Tips

Due to the immense regional popularity of the Maryland side of Great Falls, parking lots frequently fill to absolute capacity on fair-weather weekends between mid-morning and mid-afternoon. To secure a stall without waiting in line along MacArthur Boulevard, plan to arrive before 9:00 AM or after 3:30 PM. The park entrance is strictly cashless, so keep a credit card, digital pass, or physical America the Beautiful / Interagency Pass ready upon approach. If the main tavern lot is full, consider alternative upstream or downstream access points such as Carderock Recreation Area or Anglers Inn (Swain's Lock). Finally, observe all posted sunset closing hours, as vehicle gates are locked promptly at dusk.
