Reservations open up quickly at Smallwood State Park Campground, and booking six or more weeks out is common for summer weekends. The single camping loop holds just 15 sites, a mix of tent and cabin spots, with electric hookups available and a nightly rate ranging from $27 to $65. Access into the campground can be rough, so drivers with larger rigs should note the 30-foot RV length limit before heading out. The park sits near Marbury in southern Maryland, roughly an hour south of Washington, D.C., making it a workable overnight stop for those coming from the metro area.
Sites are well-spaced and heavily shaded, with thick foliage providing a reasonable degree of privacy between neighbors. A footbridge over the creek connects the camping loop to the marina and day-use area, where campers have access to a fishing pier, boat launch, and a small store. Anglers and paddlers tend to get the most out of this park. Lorraine P. notes that "Mattawoman Creek is right there and great for kayaking." The historic Smallwood mansion is also accessible on foot, though hours are limited and worth checking before planning a visit.
The bathhouse is older and can attract bugs, but multiple reviewers describe it as reasonably clean and well-stocked. Sites 10 through 14 come up frequently as the most desirable. One caveat: on busy summer weekends, amplified music from the day-use area has carried through the campground, so lighter sleepers may want to plan accordingly. For a wider look at the region, campgrounds around Smallwood State Park provide additional context on nearby options. The campground runs March through October, and those who value low site counts and direct water access tend to come back.
