How to Visit Great Falls (Maryland and Virginia): Billy Goat Trail, C&O Canal, and the Best Views

Plan your visit to Great Falls Park with this guide to the Maryland and Virginia sides, including the Billy Goat Trail, C&O Canal, overlooks, parking tips, and best viewpoints.

Estimated reading time: 17 minutes

Great Falls is one of those places around Washington DC that almost everyone has heard of, but not everyone realizes how much there actually is to explore there.

Most people show up expecting a quick waterfall viewpoint. And yes — the views are incredible. The Potomac River crashes through a narrow rocky gorge here, creating one of the most dramatic natural landscapes in the Mid-Atlantic.

But the area is bigger and more interesting than many first-time visitors realize.

One thing that confuses people right away is that Great Falls actually has two entrances — one in Maryland and one in Virginia. They look at the same section of river, but they offer very different experiences.

The Virginia side is best known for the dramatic waterfall overlooks. The Maryland side, which is part of C&O Canal National Historical Park, is where you’ll find the historic canal, the Great Falls Tavern Visitor Center, and the famous Billy Goat Trail.

If you have time, it’s worth seeing both.

Visiting the Maryland Side of Great Falls

The Maryland side of Great Falls has a slightly different feel from the Virginia entrance.

Instead of immediately heading to the waterfalls, visitors arrive at the Great Falls Tavern Visitor Center, surrounded by canal locks, shaded trails, and historic buildings.

This part of the park feels quieter and more historical.

From the visitor center area you can:

walk along the C&O Canal towpath
visit several overlooks of the Potomac River
hike the Billy Goat Trail
explore canal lock structures
take seasonal canal boat rides

If you enjoy both nature and history, the Maryland side is incredibly interesting.

Visiting the Virginia Side of Great Falls

If it’s your first time visiting Great Falls, there’s a good chance you’ll end up on the Virginia side first. That’s where many people go when they want to see the waterfalls without doing much hiking.

The entrance road winds through the woods for a bit before you reach the main parking area. From there, the walk to the overlooks is surprisingly short. Within a few minutes you start hearing the river, and once you reach the first viewing platform the scene opens up pretty dramatically.

The Potomac squeezes through a narrow section of rock here, breaking into multiple waterfalls and rapids. When the water level is high, the river looks powerful enough to rearrange the entire landscape.

Most visitors spend their time moving between the three overlook platforms. They’re close enough together that you can see all of them in a fairly short visit, but each one gives you a slightly different angle on the falls.

The first overlook sits closest to the main drop in the river. It’s the spot where you really notice how loud the water is. A lot of people linger here for a while just watching the rapids tumble through the rocks.

The second overlook is where many photos get taken. From this angle you can see several cascades moving around rocky islands in the middle of the river, which makes the whole scene feel wider and more dramatic.

The third overlook looks farther down the gorge. The waterfalls aren’t as close from this vantage point, but you get a better sense of the scale of the river and the cliffs around it.

Even though the overlooks are the main attraction, there are a few other trails in Great Falls Park on the Virginia side if you feel like walking a little farther. The River Trail follows the edge of the Potomac for a while, and the Ridge Trail heads back through the forest and is usually quieter.

Some hikers also continue toward Difficult Run, where a small stream meets the Potomac and forms another waterfall. It’s not nearly as dramatic as Great Falls, but it’s a nice spot if you’re already exploring the park.

For many visitors, though, the overlooks are the highlight. It’s one of those places where you can stand for a few minutes watching the water and then realize you’ve been there much longer than you expected.

Great Falls Tavern Visitor Center

The Great Falls Tavern Visitor Center reopened in 2020 and is definitely worth stopping into during your visit.

Originally built in the early 1800s, the tavern once served travelers and canal workers moving goods along the Chesapeake and Ohio Canal.

Today it operates as a small museum and information center where visitors can learn more about the canal and the surrounding landscape.

Inside the visitor center you’ll find exhibits about:

designing and building the canal
how canal locks worked
the history of the Great Falls Tavern
life along the canal in the 1800s
the economic impact of canal trade

There are also artifacts, historic photographs, and newspaper articles showing how important the canal once was to transportation and commerce.

Kids can participate in the Junior Ranger program. You pick up a Junior Ranger booklet, complete the activities, and then return to the visitor center to be sworn in by a park ranger.

It’s surprisingly fun and a great way to keep kids engaged while exploring the park.

Parking is available on site.

The entrance fee is typically $20 per car, which also works on the Virginia side. There is also an annual pass option available.

Walking the C&O Canal Towpath

Behind the visitor center you’ll find the C&O Canal towpath, one of the most relaxing trails in the region.

The towpath stretches nearly 185 miles from Washington DC to Cumberland, Maryland, following the entire length of the historic canal.

This path once allowed mules to pull cargo boats along the canal. Today it’s a flat dirt trail that is ideal for walking or biking.

You’ll often see people:

biking long sections of the canal
jogging along the shaded trail
taking a relaxed family walk
stopping to fish or watch wildlife

One of the interesting things about this area is how calm the canal feels compared to the nearby river.

The canal water is still and quiet, while the Potomac River just beyond the trees is crashing through rocks and rapids.

Canal Boat Rides at Great Falls

One of the most unique experiences at Great Falls is the chance to ride a replica canal boat.

Visitors can ride aboard the Charles F. Mercer canal boat, which recreates how transportation worked along the canal in the 1800s.

During the ride, park staff explain what life was like for canal workers and how goods were transported along the waterway.

The boat is pulled by mules, just like the original canal boats were.

Typical ride details include:

Ride length: about 45 minutes
Capacity: about 25 passengers
Tickets: first come, first served

Historically, rides have been offered on summer weekends, with departure times around late morning and early afternoon.

Tickets are usually distributed about an hour before each ride.

Even if you don’t take the boat ride, watching the canal boat move through the lock system is fascinating.

Hiking the Billy Goat Trail

If you spend any time researching Great Falls, the Billy Goat Trail will come up almost immediately. It’s probably the most famous hike in the Washington DC area, and for many people it’s the main reason they visit the Maryland side of the park.

The trail runs along the cliffs above the Potomac River and passes through some surprisingly rugged terrain. In several places the path winds over huge boulders with views of the river rushing through the gorge below.

What many visitors don’t realize at first is that the Billy Goat Trail isn’t just one trail. It’s actually divided into three sections, and they are very different from each other.

Section A

Section A is the one most people are talking about when they mention the Billy Goat Trail.

This part involves real rock scrambling. You’ll climb over large boulders, squeeze through narrow rock passages, and occasionally use your hands for balance while moving across uneven terrain. It’s fun and scenic, but it’s definitely more challenging than a typical hiking trail.

The distance is only about 1.7 miles, but it usually takes hikers two to three hours to finish because progress is slow in the scrambling sections.

Dogs are not allowed on this section of the trail.

It’s an incredible hike, but it’s not ideal for young kids or anyone who isn’t comfortable navigating rocky terrain.

Section B

Section B feels very different.

Instead of scrambling over rocks, the trail winds through wooded areas with occasional views of the Potomac River. It’s quieter and much less crowded than Section A.

The distance is about 1.4 miles, and the terrain is more typical of a moderate hiking trail.

Dogs are allowed here, which is another reason many locals choose this section.

Section C

Section C is the easiest portion of the Billy Goat Trail.

The terrain is flatter and more manageable, making it a good option for families or visitors who want a scenic walk without the rock climbing.

It’s about 1.5 miles long and still offers glimpses of the river along the way.

For many first-time visitors, this section is a nice introduction to the area.

Parking for the Billy Goat Trail

Parking is often the most frustrating part of visiting the Billy Goat Trail.

Most hikers start from the Great Falls Tavern Visitor Center parking lot, which provides access to the canal towpath and the trail entrance for Section A.

On weekends the lot fills quickly, especially in spring and fall. If you’re planning to hike Section A, arriving earlier in the morning usually makes things easier.

Some hikers also access other sections of the trail from smaller pull-offs along MacArthur Boulevard, but those spaces are limited and sometimes require a longer walk to reach the trail.

A Few Helpful Trail Tips

A few small things can make the hike much more enjoyable.

Wear sturdy shoes. The rocks on Section A can be slick, especially after rain.

Bring water. There are no water fountains along the trail.

Take your time. The scrambling sections slow people down more than they expect.

Watch kids carefully. Some parts of the trail run close to steep drop-offs along the river.

Despite the challenge, the Billy Goat Trail is one of the most memorable hikes near Washington DC. The views of the river, the rocky landscape, and the constant sound of rushing water make it feel much more remote than it actually is.

The Great Falls Overlooks

One of the nice things about visiting Great Falls is that you don’t necessarily have to hike very far to see the river doing its thing. There are overlook areas on both the Maryland and Virginia sides where you can stand above the Potomac and watch it crash through the rocks.

The two sides give you slightly different perspectives.

The Virginia side is the one most people think of first because the overlooks sit right above the main waterfalls. If you’ve seen dramatic photos of Great Falls, chances are they were taken from one of these viewing platforms.

The Maryland side is a little different. The viewpoints are still impressive, but they’re woven into the trail system and the canal area rather than sitting directly above the falls.

If you have time, seeing both sides really gives you the full picture.

Virginia Overlooks

From the Virginia parking lot, it’s a short walk to three overlook platforms. The path between them is paved and pretty easy, so most visitors just wander from one to the next.

The first overlook is closest to the main drop in the river. When the water level is high, this spot is loud. The Potomac squeezes through a narrow channel of rocks and explodes into whitewater. It’s one of those places where you instinctively step closer to the railing just to watch the water for a few minutes.

The second overlook gives you a wider view of the river. Instead of focusing on one waterfall, you can see multiple cascades moving around rocky islands in the middle of the gorge. A lot of people end up taking photos here because it shows more of the landscape.

The third overlook looks farther downstream. You don’t see the main falls as clearly, but you get a better sense of how the river winds through the rocky canyon. It’s a good place to stop if you want a big panoramic view of the gorge.

Maryland Views

On the Maryland side, the viewpoints feel a little less formal.

If you start at the Great Falls Tavern Visitor Center, a short path leads to several platforms where you can look out over the river. The waterfalls are farther away from this side, but you still get a great look at the rapids pushing through the rocky channel.

A lot of people end up seeing these overlooks while walking along the canal towpath or heading toward the Billy Goat Trail.

If you hike Billy Goat Trail Section A, there are also several spots along the cliffs where the trees open up and you can look down at the river below. They’re not official viewing platforms, but some of those views are actually more dramatic than the overlook decks.

A small photo tip

Lighting at Great Falls changes the look of the river quite a bit.

Morning tends to work better on the Maryland side of the gorge, while the Virginia overlooks often photograph nicely later in the afternoon when the sun moves across the river.

Spring visits can be especially impressive because the river flow is usually stronger after rain and snowmelt.

Parking at Great Falls

Parking is often the biggest challenge when visiting Great Falls.

The Maryland and Virginia entrances are not connected, so you must decide which side you want to visit first.

Maryland parking is located at the Great Falls Tavern Visitor Center lot.

The Virginia side has larger parking areas and easier access to the waterfall overlooks.

On busy weekends — especially during fall foliage season — arriving early makes a big difference.

Frequently Asked Questions

Final Thoughts

Great Falls is one of those places that surprises people.

From the overlook platforms, it’s easy to forget that you’re only a short drive from Washington DC. The rushing river, towering rock walls, and winding gorge feel much more remote than they actually are.

Whether you’re hiking the Billy Goat Trail, walking along the canal towpath, or simply watching the waterfalls from the overlooks, Great Falls is a place that tends to stick with you.
