RV Campgrounds in Maryland: Hookups, Sites, Honest Reviews

Maryland is a small state pretending to be five — a barrier-island marsh on one end, an Allegheny plateau on the other, with Piedmont farmland and the tidal Chesapeake jammed between. You can drive the whole thing in a long day. What that means for RV camping is that the campgrounds don't share a logic; a full-hookup site near Ocean City is doing entirely different work than a 30-amp pull-through in Garrett County, and pretending otherwise leads to the kind of generic listicle I try not to write.

Most of the public-land sites you'll book in this state were laid down by the CCC in the 1930s or built out during the mid-century state-parks expansion, when the loops were sized for a Coleman and a station wagon, not a 38-foot fifth wheel. That history is still in the road geometry. I'll point out where it bites.

The Eastern Shore: Marsh, Pine, and a Lot of Wind

If you're hauling an RV to Maryland for the first time, the Eastern Shore is probably where you're aiming, and probably for the wrong reasons. People want Assateague. Fine. But understand what you're getting into.

Assateague State Park (off MD-611, south of Ocean City) sits on a barrier island that physically migrates west. The campground has electric hookups at a portion of sites, no sewer, and dump stations on site. The wind is constant, the sand gets into everything, and the horses — the famous feral horses, descended from Colonial-era livestock — will absolutely walk through your site and chew on a folding chair. I love it there. I would not bring a brand-new rig. Shoulder season (late April, October) is the only time I'd consider it; July on Assateague is a meteorological event.

Just inland, Pocomoke River State Park (Shad Landing area, near Snow Hill) is the quieter pick and the one I usually recommend. It's a loblolly pine and bald cypress system — the northernmost reach of cypress on the Atlantic coast, which is a geolgoical and botanical curiosity worth a paragraph in its own right. Electric and water at many sites, a dump station, and a camp store that operates on its own schedule. The land here was Pocomoke and Nanticoke before European contact; the river name carries forward, the people were displaced south and west.

For full hookups on the Eastern Shore, you're looking at private RV parks. Castaways RV Resort (Berlin, near the Verrazano Bridge to Assateague) and Frontier Town (also Berlin) are the two big operations. They are not subtle. They are full-service, with pools and shuttles and the entire summer-vacation apparatus. If that is what your family wants, they deliver it. Just don't tell me you went to the Eastern Shore for nature and then parked between two diesel pushers running generators.

The Chesapeake and Northern Bay

The mid-Bay region is underrated for RV camping, partly because the public sites are smaller and book up fast through Maryland DNR's reservation system.

Elk Neck State Park (North East, at the head of the Bay) is the standout. Mixed terrain — bay beach, hardwood ridge, a working lighthouse at Turkey Point — and a campground with electric loops, a dump station, and some sites that can fit a mid-size travel trailer comfortably. The roads were not designed for big rigs; a 30-footer is the upper limit I'd attempt, and even that requires patience at the loop entrances. The Susquehannock had villages near the head of the Bay before they were pushed out by disease and warfare in the 1600s, and the bluff above the campground gives you a sense of why they were here.

Janes Island State Park (Crisfield) has electric sites and a dump station, and is essentially a launching pad for kayaks into one of the better paddling trail systems on the East Coast. It's a long drive to get there from anywhere. That's a feature.

Susquehanna State Park (Havre de Grace) is small, wooded, and historically rich — the Rock Run mill complex, the Stafford ironworks ruins downriver — and offers electric hookups at a portion of sites. The campground itself is a CCC-era layout; tight turns, a few sites you should not try to back a long trailer into. I have watched it go badly.

Western Maryland: The Plateau, the Lake, the Old Logging Country

Garrett County is where my preferences live. Most of what is now state forest and park out here was scalped between roughly 1880 and 1920 by the lumber companies — Garrett, Davis, the West Virginia operators — and what you camp in today is second-growth northern hardwood that has had a hundred years to reassemble itself. It is not wilderness. It is a recovery. The distinction matters.

Deep Creek Lake State Park (Swanton, off US-219) sits on a reservoir built in 1925 for hydropower, not recreation; the lake is a happy accident of the Youghiogheny River drainage being dammed for a power plant that is still operating. The campground has electric sites, a dump station, and one of the better swim beaches in the state park system. Summer weekends here are a scrum. Mid-week in September is sublime.

New Germany State Park (Grantsville) is smaller, higher elevation, cooler in summer by ten degrees than anywhere east of Hagerstown. Electric at some sites. CCC-built lake and cabins. The roads are tight but manageable for moderate rigs.

Rocky Gap State Park (Flintstone, off I-68) has the most accommodating loop geometry for larger RVs in western Maryland, electric hookups widely available, and a dump station. The casino-resort next door is a strange neighbor for a state park but you can ignore it from the campground.

Big Run State Park (Savage River Reservoir, near Grantsville) is primitive — no hookups, no real RV infrastructure, and I'm only mentioning it because people ask. Don't bring a Class A. Don't bring a Class C either, frankly.

Near the Cities: The Cherry Hill Question

Most roundups of Maryland RV parks lead with Cherry Hill Park (College Park, off I-95), and the the reason is straightforward: it is the closest full-hookup RV park to Washington, D.C., with a Metro shuttle, full hookups including 50-amp, cable, Wi-Fi, and the operational competence of a place that has been doing this for decades. It is not cheap. It is not quiet (you are wedged against I-95, the Beltway is audible). For a family parking the rig and spending three days at the Smithsonian, it is the answer. For a nature trip, it is not.

Bar Harbor RV Park (Abingdon, north of Baltimore) is the equivalent play for the Baltimore side — full hookups, family-oriented, easy interstate access. Functional. Not scenic.

The Catoctin and Central Piedmont

Greenbrier State Park (Boonsboro, off US-40) has electric sites, a dump station, and a CCC-built lake that is one of the prettiest swimming holes in the central part of the state. The campground loops are forgiving for medium rigs. The South Mountain ridge above it is the same ridgeline you'd hike on the Appalachian Trail; in fact the AT crosses just east of the park, and a day of hiking from camp is easy to arrange.

Cunningham Falls State Park (Thurmont, adjacent to Catoctin Mountain Park) splits its camping between the Manor and William Houck areas; both have electric loops and dump stations. The 78-foot cascade the park is named for is a short walk from the William Houck campground and the only sizable waterfall in this part of Maryland. The Catoctin range is metarhyolite — old, hard, volcanic rock — which is why the falls exist; softer country erodes flat.

What "Full Hookup" Actually Means Here

A note on language, because the marketing copy gets sloppy. In Maryland's public campgrounds, "hookup" almost always means electric only — 30-amp at most loops, 50-amp at a smaller subset, water at some sites, sewer at almost none. Dump stations are standard. If you need true full hookup (electric, water, sewer at the site), you are booking a private RV park, and your options narrow to roughly:

• Cherry Hill Park — College Park; closest to D.C., 50-amp, premium
• Bar Harbor RV Park — Abingdon; Baltimore side, family-oriented
• Castaways RV Resort — Berlin; Ocean City access, resort amenities
• Frontier Town RV Park — Berlin; Western-theme park attached (yes, really
• Sun Outdoors Ocean City — Berlin/West Ocean City; chain operation
• Yogi Bear's Jellystone Hagerstown — Williamsport; western terminus of I-70 corridor

For everything else — and "everything else" includes most of the genuinely beautiful camping in this state — you will be dumping at a central station and filling your fresh tank before you leave, which is how RV camping used to work everywhere and is not actually a hardship if your rig is set up for it.

Booking, Seasons, and the Reservation Reality

Maryland DNR uses a centralized reservation system; popular sites at Assateague, Deep Creek, and Cunningham Falls release a rolling window that fills within minutes for summer weekends and you should treat the release morning like a concert ticket drop because waiting until June to plan an August Bay weekend at Elk Neck is how you end up at a KOA off I-95 instead. Check the DNR public lands page for current windows and fee structures; I won't quote prices that drift. Assateague State Park books differently from Assateague Island National Seashore (administered by the NPS) — same barrier island, two reservation systems, and if you want the National Seashore loops you go through Recreation.gov.

I camp in shoulder season whenever I can. Late April through mid-May, and September into early October, are the windows where Maryland weather actually behaves and the campgrounds are not full of people who would rather be at a hotel. Browse our parks index and trail listings if you want to pair a campground with a specific hike; the Catoctin and South Mountain corridors are particularly easy to plan around.

Honest Take

If I were planning a Maryland RV trip tomorrow, I'd go to Rocky Gap or Deep Creek in late September, take the electric-only site, dump on the way out, and skip the full-hookup-resort circuit entirely. For a family with kids who want a pool and a shuttle, Cherry Hill near D.C. or Castaways near Assateague genuinely deliver what they advertise. The rest of the marketing-driven roundups will tell you every campground is a destination; most are not, and the ones that are tend to be the ones the CCC built in the 1930s on land that was already, by then, recovering from something. Bring layers, a decent camp stove, and a willingness to drive a little further than the listicle suggests. The rest of your gear matters less than people pretend.
