Side Trips Worth Taking: Cruising the Potomac River to Washington, D.C.
If you’re cruising the Great Loop and debating whether to detour up the Potomac River—this is your sign to go for it. While it adds some miles to your route, the trip is well worth it. Whether you’re history buffs, museum hoppers, or just want a change of pace, cruising to Washington, D.C. offers a mix of serene anchorages, vibrant waterfronts, and iconic sights you won’t want to miss.
We took this side trip as a family and still talk about it as one of the most memorable stretches of our journey. It’s a rare thing to cruise your own boat right into the heart of the nation’s capital. Here’s a quick cruising guide to help you make the most of your time on the Potomac.
Moorings, Marinas & Anchorages
The Wharf Marina (Washington, D.C.)
This is one of the best jumping-off points for exploring the city. We picked up a mooring ball near The Wharf, which made a perfect home base. From there, we could dinghy to the marina dock, tie up, and catch the free shuttle up to the National Mall.
Gangplank Marina (Washington, D.C.)
Right in the thick of things, this marina is located along the city’s bustling waterfront with restaurants, a fish market, and events just steps away.
National Harbor (Oxon Hill, MD)
Further downriver, National Harbor offers slips and moorings, plus access to shops, the Capital Wheel, and riverfront activities.
Colonial Beach (VA)
A charming stop along the way with a laid-back, old-school beach town vibe. It’s a good place to pause before heading further upriver.
Mallows Bay Anchorage
Mallows Bay is home to the Ghost Fleet—a hauntingly beautiful collection of sunken wooden ships from World War I. Anchoring here feels like stepping into a living museum, and the kayaking is unforgettable. We stopped just for an hour when the tide was low to drive our dinghy around the fleet and see the old ships in their grave.

Tips for Cruisers
Plan ahead. D.C. can get busy, especially in spring and summer. Book marinas and mooring balls early if you’re going during peak season.
Use public transport. Once you’re moored or docked, take advantage of public shuttles, the Metro, or bikes/scooters to explore.
Give yourself time. There’s so much to see—it’s easy to spend a week or more and still not get to it all.
Weather and current. The Potomac has some current and wind-driven conditions to watch for, especially in narrow channels.
A Unique Perspective on the Nation’s Capital
Cruising into D.C. is unlike arriving any other way. You’re navigating waters that once carried tall ships, war fleets, and now—your own adventure. The experience is both humbling and exhilarating.
Whether you’re anchored near quiet coves or docking beside bustling piers, the Potomac offers a mix of nature and history that makes this side trip unforgettable. It might not be an “essential” part of the Loop, but for us, it was absolutely worth it.
