Ride the Tidewater Potomac
This loop starts and ends in Washington, D.C., running down the Virginia side of the Potomac through the Northern Neck, crossing the river into Southern Maryland, and returning north to the capital.
What to Expect
This route lies within the Potomac Heritage National Scenic Trail corridor, tracing both sides of the lower Potomac River through fingers of land called necks that reach down toward the water. Expect quiet country roads, tobacco barns and farm fields, marshes full of herons, and wide river views that open up toward the Chesapeake Bay. The pace stays easy and history-focused, with museums and colonial-era sites woven throughout, and while the rural necks grow quiet, services are never far off. It can be ridden in either direction.
Several sites connect directly to George Washington, including Mount Vernon, George Washington’s Ferry Farm, where he lived from age six into early adulthood, and the George Washington Birthplace National Monument. The route also passes through Southern Maryland’s Amish farm country and quiet bay towns like Leonardtown and Historic St. Mary’s City, Maryland’s first capital, with the historic Point Lookout Lighthouse marking the tip of the Maryland peninsula.
Washington, D.C., Virginia, and Maryland all run flat to rolling here, with a few short hills along the way. The route’s elevation ranges from sea level to just 430 feet, making this one of the network’s gentler rides. The full route includes detailed riding conditions and field notes for the entire loop.
Services are generally steady given this route’s proximity to Washington, D.C., though the Northern Neck of Virginia and Southern Maryland grow quieter and more rural, with services spaced farther apart. Cell coverage is generally reliable, and bike shops are concentrated around Washington, D.C., so carry spare tubes and basic tools for the rural stretches.
Ride this route roughly spring through fall. Mid-Atlantic summers bring heat, humidity, and afternoon thunderstorms, while fall offers cooler temperatures and fewer bugs. Late summer and fall can bring tropical storms to the tidewater region. Winter riding is possible but less common, given the exposed river and bay crossings.
Route Sections
Washington, D.C. to Washington, D.C., 377 miles
From Washington, D.C., the route follows Ohio Drive through East and West Potomac Park before crossing the river onto the busy Mount Vernon Trail in Virginia, part of signed U.S. Bicycle Route 1. It continues south through the Northern Neck of Virginia, crosses the Potomac into Southern Maryland’s necks and peninsulas past Port Tobacco and Leonardtown, and reaches the Chesapeake Bay near Point Lookout before returning north to close the loop in Washington, D.C. The full route includes turn-by-turn directions, service information, and field notes for the entire loop.

Plan Your Ride
This loop’s easy terrain and Washington, D.C., make it approachable for riders of many experience levels, with flexible spur options along the way.
Trip Planning & Logistics
Washington, D.C., offers major airport, Amtrak, and bus access, making this an easy loop to start without a car. The route can be ridden clockwise or counterclockwise, and it connects to the C&O Canal Towpath for riders continuing toward the Chicago to New York City route’s Philadelphia Alternate, as well as to the Atlantic Coast route in Washington, D.C. Most riders plan five to eight days for the full loop, depending on how many spurs and side trips they add. This route is available as a digital route through Adventure Cycling’s shop and includes routing, detailed service information, riding conditions, and field notes for trip planning.
This route runs mostly on pavement, so a standard touring or road-touring bike suits it well, and slightly wider tires help on the unpaved C&O Canal Towpath. Pack insect repellent and sun protection for the tidewater marshes and open river crossings.
Lodging and camping are available along the route, with fuller options near Washington, D.C., and the larger towns, and state parks on both sides of the river making good overnight stops. Options thin out in the rural necks of Southern Maryland and Virginia’s Northern Neck, so plan ahead there. Some campgrounds charge solo cyclists the same as a full tent or RV site, and Warmshowers hosts are an option in the D.C. area.
Services are steady near Washington, D.C., and grow more spread out through the Northern Neck of Virginia and Southern Maryland, where small towns like Port Tobacco, Charlotte Hall, and Leonardtown offer good resupply points. Along the way, look for Maryland blue crabs, Chesapeake oysters, and Southern Maryland stuffed ham. Check your digital route in Ride with GPS for service phone numbers, and call ahead for anything outside peak season.
The sidewalk narrows with heavy traffic just after the Maine Avenue Fish Market in Washington, D.C., so walk your bike under the railroad overpass there. The Mount Vernon Trail is heavily used by cyclists and pedestrians, so ride at a considerate pace. Signage on U.S. Bicycle Route 1 in Virginia can be inconsistent, so follow your digital route when signs conflict. Watch for faster traffic on the few rural highway stretches, deer at dawn and dusk, and ticks after riding or camping in grassy or wooded areas.
Always check Adventure Cycling Route Updates and Corrections before you go.
Routes change. Bridges wash out, businesses close, and construction pops up overnight. We strive to keep routes updated as those things happen. When we learn about a change, we reroute around sections that have become dangerous or are temporarily closed for road work, bridge outages, or construction, and we update service information as businesses open, close, or move. Digital routes are updated as soon as we’ve reviewed a reported issue.
You’re often the first to spot these changes out on the road. Help us keep this route accurate for the next rider by reporting anything you notice with our Route Feedback Form.

Frequently Asked Questions
It’s our flagship, staff-built route network. The one that started it all 50 years ago with the TransAmerica Trail, the route that launched bicycle touring and bikepacking in America. Every route in it is designed and researched by our own team of cyclists and cartographers: months of research and on-the-ground testing go into each one, so what you get is more than a line on a map. Each Adventure Cycling route has detailed logistics, terrain and elevation info, points of interest, camping and lodging, safety alerts, and history, all in one place. It’s the most in-depth of our three networks, available as digital routes and most as paper maps too. It’s the route network we update most regularly as conditions change.
They’re related, but not the same thing. The Adventure Cycling Route Network is made up of routes we’ve researched, ridden, and mapped ourselves, chosen specifically for a great touring or bikepacking experience. The U.S. Bicycle Route System (USBRS) is a state-by-state national system that we serve as technical experts for, made official through each state’s department of transportation. The two overlap in a lot of places, but an ACRN route carries our own on-the-ground vetting; a USBRS route carries official state recognition.
It depends! If you want a route we’ve personally scouted end to end, with services, camping, and terrain notes built in, start with the Route Network. The ACA Route Network has routes of many different lengths and can be a much easier starting place for someone new to bicycle travel. If you’re an experienced cyclist piecing together an officially designated corridor, or riding somewhere the two systems converge, the interactive USBRS map is a good resource to use.
The Adventure Cycling Route Network is a premium network because of everything that goes into it. Unlike the U.S. Bicycle Route System (built by state DOTs) or Short Routes (submittedby cyclists in their own communities), every Adventure Cycling route is researched, ridden, and vetted end-to-end by our own team. Unlike other routes, Adventure Cycling routes come with extensive information on riding conditions, terrain notes, camping and lodging info, logistics, safety alerts, and points of interest. We also keep it current as roads and services change. The price supports that ongoing research and maintenance work, done by a nonprofit whose whole mission is making sure the route in your hands is one you can trust.
Turn-by-turn directions with a bike icon aren’t the same as a route built for specifically touring or bikepacking. Every mile in the Adventure Cycling Route Network has been researched and ridden by our staff and researchers, chosen to avoid dangerous traffic, and mapped with what a touring cyclist actually needs — food, water, camping, hotels, bike shops — spaced out along the way. The Adventure Cycling Route Network was built for cyclists by cyclists, is regularly updated, and comes with the resources and information needed to plan your ride.
No. The network includes routes for a wide range of experience and difficulty levels, from a first multi-day trip to a cross-country expedition. What every route has in common is that it was chosen with a touring cyclist’s needs in mind, whatever kind of trip you’re planning.
Not at all. Alongside iconic long-distance routes like the TransAmerica Trail, the network includes shorter regional routes, so it works for a weeklong vacation or a two-month journey.
For many years, we focused on paved routes, but today the network includes plenty of unpaved gravel riding for bikepacking. In fact, Adventure Cycling mapped the Great Divide Mountain Bike Route in 1998, arguably the most impactful bikepacking route in the world. The Adventure Cycling Route Network also includes the Golden Gravel Trail, Idaho Hot Springs Mountain Bike Route, Arkansas High Country Route, and more. Some routes are a 50/50 mix of pavement and gravel. Some routes follow paved and unpaved bike paths and rail trails. The Adventure Cycling Route Network has terrain for every cyclist.
We revisit our printed maps every three to five years, and push corrections to our digital route data as we learn about changes on the ground. If you have an Adventure Cycling Route in Ride with GPS that we’ve updated, you’ll get a notification when you open the route to update to the newest version of the route. Updating will ensure you have the latest data, information, and points of interest vital to being on route. For cyclists who have Adventure Cycling paper maps, we keep a list of route- and section-specific updates current on our Map Updates and Corrections page.
Change comes from two directions: our own staff research and reports from the cyclists actually out there riding them. If a bridge washes out, a shoulder disappears, a campground closes for repairs, or a town loses its only grocery store, that’s the kind of thing that triggers an update. You can help us keep our routes accurate; fill out our Route Feedback Form.
Most of our Adventure Cycling Routes come as waterproof print maps and digital Ride with GPS navigational data. Our print maps are the #1 longstanding popular resource for traveling cyclists. They are waterproof, highly detailed and always work. For long trips, many cyclists use a combination of print maps and digital routes.
If you’re already comfortable and familiar with a GPS navigational aid such as Ride with GPS or a Garmin, our digital data packages are an excellent choice. We do not recommend GPX data for beginners since there are a few extra steps to installing and troubleshooting.
Once you purchase a digital route, you’ll get an email with a link to unlock it in the free Ride with GPS app — no separate subscription required for basic navigation. From there you get turn-by-turn voice directions, curated points of interest like campgrounds and bike shops, and field notes on the history, geography, and climate along your route, all available 100% offline. If you’drather use a dedicated GPS device, you can export the route as a GPX file to load onto a Garmin, Wahoo, or similar device.
To export GPX files of your Adventure Cycling digital route, use your laptop or desktop to open the email you received after purchasing your digital route. Click on the link that allows you to access your Digital Route. Finally, click on EXPORT ALL at the bottom of the screen. This is the only way to export files that include the route line, points of interest, and services. Files will be exported as one ZIP file.
Adventure Cycling uses abbreviations across its paper and digital routes to indicate particular services, land or road types, route names, direction of travel, and route type. Please see our key to abbreviations.

No. The Routes and Mapping Department does not do custom routes for individuals. Check out the routes we’ve already mapped, and use the interactive map to piece our route networks together, forming a route that gets you from a point A to point B of your choice.
It started with a single route. In 1976, we mapped the TransAmerica Trail, and more than 4,000 cyclists crossed the country together for Bikecentennial — the nation’s bicentennial cycling celebration our founders organized. That one route became the seed of a network we’ve spent the decades since expanding. Today it’s more than 58,000 miles of mapped routes across the U.S. and Canada, from classic epics like the TransAmerica Trail, Great Divide Mountain Bike Route, and Pacific Coast, to shorter regional routes.
