Piscataway Creek is a tidal tributary of the Potomac River in Maryland, offering a classic Tidewater marsh paddling experience. The primary public access for paddlers is the Fort Washington Marina, located at 13600 King Charles Terrace in Fort Washington. This site, managed by the National Park Service, features two concrete boat ramps suitable for larger vessels, with a designated dock area to the left of the ramps specifically for launching canoes and kayaks. A launch fee applies, reported as $10 per boat and $5 per kayak. Parking is a large gravel lot with over 30 car spaces and 10 trailer spaces, along with permanent restrooms and other marina amenities. An alternative, simpler launch is at Piscataway Park, a free public boat ramp with parking for approximately five cars. Another car-top-only launch is at Piscataway Crossing Regional Park, which provides steps down a riverbank for access to the Potomac River near the creek's mouth; no trailers are permitted there.

As a tidal creek, water levels and currents are governed by the Chesapeake Bay's tide cycle. Paddlers should plan trips around tide tables, as the creek can become shallow at low tide, potentially limiting exploration of smaller sloughs. Launching on a rising tide is recommended to access these narrower waterways. The wind can also build quickly over the open marsh, creating chop. The creek's character is defined by extensive marshes, providing a sheltered environment once away from the highway crossings. Wildlife is abundant, with frequent sightings of bald eagles, ospreys, and great blue herons. The area holds historical significance related to Captain John Smith's explorations and the indigenous Piscataway people. The recommended paddling season spans from March through November. Paddlers should be prepared for potential motorboat traffic, especially near the marina and the confluence with the broader Potomac River.
