Captain John Smith and his crew passed by this point twice in June 1608 as they explored the Potomac River in their unfruitful search for the Northwest Passage to the Pacific Ocean. Smith and his explorers made it all the way up the river to its head at Little Falls, where they left their Discovery Barge and continued on foot to Great Falls.
Today, the area is a bustling metropolis, home to Virginians, Marylanders, and Washingtonians. Washington, D.C., our nation's capital, is a busy city -- but is just a few miles away from scenic natural areas on the Potomac.
The buoy is visible from both the Maryland and Virginia sides of the river from south of the Woodrow Wilson Bridge. Water access is available at marinas up and down both shores, including Belle Haven Marina, on the grounds of the George Washington Memorial Parkway.
Be sure to check the weather forecast before you head out.
