Great Falls Park, Potomac MD: A Local's Complete Guide

Kevin Grolig shares an insider's guide to Great Falls Park in Potomac, MD — trails, falls overlooks, fees, and why it makes Montgomery County special.

Great Falls Park is an 800-acre stretch of the Potomac River in Potomac, Maryland, known for dramatic 20-foot waterfalls, rugged river gorge trails, and some of the best hiking and kayaking in the DC area. It sits along the historic C&O Canal, has a Maryland side and a Virginia side, and charges either a $20 daily vehicle fee or a $35 annual pass. I’ve been coming here since I was a kid, and as a Compass agent working Potomac and greater Montgomery County, I still bring clients and friends out to this park because it says more about why people move here than any listing sheet ever could. If you’re weighing a move to this area, this is the kind of thing you’re actually buying into.

What Is Great Falls Park and Where Is It?

Great Falls Park sits right along the Potomac River, split between a Maryland side in Potomac and a Virginia side across the water. The Maryland side is part of the C&O Canal National Historical Park, accessed off Falls Road, and it’s the side I grew up visiting. The falls themselves cascade through a series of drops that add up to the steepest fall line rapids of any river on the East Coast, and the whole scene sits inside a quiet, wooded stretch ofPotomacthat most visitors from outside the area have no idea exists this close to a major metro.

Why Does the C&O Canal Matter Here?

The canal running alongside the park isn’t just scenery, it’s the reason this whole area developed the way it did. For close to a century, the C&O Canal moved goods and people 184.5 miles from Georgetown in DC all the way to Cumberland, Maryland, and it fueled the growth of river towns up and down the Potomac Valley before newer transportation made it obsolete. Walking the towpath today, you’re tracing the same route that carried westward expansion, Civil War-era supply lines, and generations of industry and commerce. The National Park Service maintains the canal and the surrounding historic park, and their site atnps.gov/chohhas the full history if you want to go deeper before your visit.

What Can You Actually Do There?

The short answer is almost everything an outdoors person wants in one place. The towpath between the canal and the river is the backbone for hiking, biking, and picnicking, and the water itself opens up kayaking, rock climbing, and fishing, which happens to be my favorite. I’m not a strong kayaker myself, but I’ve watched plenty of people launch right from the park in full wetsuits, so don’t let that stop you if it’s your thing. Whatever pace you’re looking for, whether that’s a flat towpath stroll or a technical scramble along the gorge, this park has a version of it.

Where Do You Actually See the Falls?

There are two main overlooks near the Great Falls Tavern Visitor Center that make this an easy stop even if you’re not up for a long hike. To the north, the Washington Aqueduct observation deck looks out over the upper falls. To the south, the Olmsted Island bridge gives you several angles on the main falls and the gorge below. Both are short walks from the visitor center, so you can get the postcard view without committing to a full day of hiking.

Is the Billy Goat Trail Worth Hiking?

Yes, if you want the close-up, rugged version of this park, the Billy Goat Trail is where you go. It’s a 4.7-mile trail split into three sections that follows the path between the canal and the river. Section A up north is 1.7 miles and by far the most popular, cutting through Bear Island with rocky, rough terrain and a steep climb along Mather Gorge. Section B runs 1.4 miles and Section C to the south covers 1.6 miles. If you only have time for one section, A is the one people talk about, but be ready for real rock scrambling, not a paved path.

What’s the History Behind the Great Falls Tavern?

The Great Falls Tavern was built in 1828 and now operates as the park’s visitor center, which is a nice touchpoint if you want history along with the hike. It houses historical exhibits and interpretive programs, and from April through October you can catch mule-drawn canal boat rides departing right from that spot. The visitor center is open daily from 9am to 4:30pm, which makes it an easy add-on whether you’re there for the falls or the story behind the canal.

What Does It Cost to Get In?

Entry runs $20 per vehicle for a day pass, or $35 for an annual pass if you know you’ll be back, and given how often locals end up back here, the annual pass pays for itself fast. Either way, the park is worth visiting throughout the year, and the crowd and scenery both shift with the seasons, so it never feels like the same trip twice.

Why Does This Matter If You’re Looking to Move to Montgomery County?

Because this is the kind of amenity that doesn’t show up in a Zillow listing but ends up mattering more than square footage. When I talk to buyers consideringrelocating to Montgomery County, I always bring up spots like Great Falls, because it’s a real signal of lifestyle, not just location. Having an 800-acre national park, river access, and serious trail systems fifteen minutes from your driveway changes how you actually live day to day, not just where you sleep at night.

And the Best Way to End a Hike?

Old Angler’s Inn, hands down. It’s my favorite stop after a long hike at Great Falls, tucked right off MacArthur Boulevard with a beer garden that’s tough to beat. If you make the trip out to the park, save room for this on the way back, it’s become part of the tradition for me and a lot of locals.
