Campgrounds and RV parks near Ashton-Sandy Spring, MD

Ashton-Sandy Spring sits in Montgomery County between the Washington, D.C. metro and the rolling farmland of the Patuxent watershed. RV renters use it as a base for the National Mall, the Smithsonian complex, and Baltimore attractions, all reachable within roughly an hour by road or transit. There are no campgrounds inside the community itself; sites are clustered on the I-95, I-270, and I-70 corridors within a 20 to 40 minute drive. Cherry Hill Park in College Park is the closest full-service RV park and markets itself as the closest campground to Washington, D.C., with shuttle and tour access to the city. Greenbelt Park Campground, run by the National Park Service about ten miles from D.C., provides a wooded, primitive alternative. Ramblin' Pines in Woodbine and the Washington DC / Capitol KOA Holiday in Millersville widen the options to the northwest and east. Patapsco Valley State Park - Hollofield Area rounds out the list on the Baltimore side, though renters should check current status before booking.

Reservations run on three different systems in this area. Greenbelt Park Campground is a National Park Service facility; sites must be reserved online through Recreation.gov, walk-in and cash or check drop-box payment are no longer available, and there are no electric or water hookups, though hot showers and a dump station are available to registered campers. The booking window is six months in advance. Maryland state parks, including Patapsco Valley State Park, use the state's parkreservations.maryland.gov portal. Reservations can be made up to 365 days ahead, so a stay a year out opens on the same calendar date the prior year. The Hollofield area campground is currently closed for renovations, though the Hollofield day-use area and pavilions remain available. Cherry Hill Park, Ramblin' Pines, and the Washington DC / Capitol KOA Holiday are private parks and book directly through their own websites or the KOA reservation system.
