221 Maryland RV Dump Stations - Sani-Dumps Directory 2024

Sanidumps.com lists {{stationCount}} dump stations across Maryland, with {{freeCount}} offering free disposal. While the count is lower than larger states, Maryland's compact size means dump stations are within reasonable driving distance from most campgrounds. Coverage spans from the western mountains to the coast.

Little Bennett Regional Campground in Clarksburg (Montgomery County) is the closest campground to DC with dump station access, about 30 miles north of the National Mall. Cherry Hill Park in College Park is a private option closer to the city. Neither is "in" DC, but Metro access makes day trips into the city practical.

The Chesapeake Bay Bridge (US-50) handles RVs regularly, but it's narrow with no breakdown lane. High winds can restrict large vehicles -- the Maryland Transportation Authority will stop high-profile vehicles when sustained winds exceed 40 mph. Summer weekend eastbound traffic can back up for hours on Friday afternoons. Consider crossing early morning or midweek.

The Assateague State Park side accommodates rigs up to 40 feet with electric hookups and a dump station. The National Seashore side has more primitive camping with size restrictions. Reserve well ahead for summer weekends. Both sides offer beachfront sites, but the wild ponies will investigate your campsite -- never feed them.

Western Maryland's Garrett County offers mountain camping around Deep Creek Lake with cooler summer temperatures than the rest of the state. State parks like New Germany and Herrington Manor have campgrounds with dump access. The scenery is Appalachian -- forested mountains, waterfalls at Swallow Falls State Park, and fall color that rivals New England.

I-95 through the Baltimore-Washington corridor is consistently among the worst traffic in the country. Rush hour extends from 6-10 AM and 3-7 PM on weekdays. Summer Fridays heading to Ocean City on US-50 are equally bad. Plan to transit through during off-peak hours -- early morning, late evening, or midday. Weekends are better but not great.

True boondocking is very limited in Maryland due to the lack of federal public land. Green Ridge State Forest in Allegany County allows primitive camping at designated sites for a small fee -- it's the closest thing to boondocking in the state. Some Walmart and rest area locations permit overnight stays informally, but Maryland's dense population makes finding isolated spots difficult.

No if you're carrying propane. The Baltimore Harbor Tunnel and Fort McHenry Tunnel on I-95 prohibit vehicles with propane tanks. You must detour via I-695 around the city, adding about 30 minutes. Signs warn well in advance, and violations result in citations. Empty propane tanks still count as prohibited.

The {{freeCount}} free sanitary dump stations scatter across state forests and select municipal parks, concentrated in Western Maryland counties. Garrett County has several free options near Deep Creek Lake. Ocean City area offers almost no free dumps -- everyone charges during summer. Check individual listings for seasonal closures and water availability.

Absolutely for summer weekends. Assateague State Park campground sells out three to six months ahead for June through August dates. The reservation window opens exactly six months in advance at 8 AM -- set an alarm. Walk-up sites occasionally open mid-week during shoulder seasons, but don't count on it for beach camping.

It's illegal statewide. Maryland prohibits overnight parking at all rest areas and welcome centers, and State Police actively enforce this. You'll get knocked on and told to move, even at 2 AM. Use truck stops, campgrounds, or ask permission at Walmart locations instead. Cracker Barrel restaurants generally allow RV parking overnight.

Not in mountain areas. Western Maryland stations close November through March due to freezing temperatures. Ocean City and Eastern Shore facilities mostly stay open year-round, though some reduce hours off-season. State park campgrounds follow their camping season schedules. Always call ahead for winter dumps -- frozen lines shut down stations without warning.

Expect $5-15 at most locations. State park campgrounds charge $5-8 for registered guests, sometimes free with camping fees. Private campgrounds near tourist areas hit $15-20 for non-guests during peak season. Truck stops run $10-12 with 24-hour access. The {{freePct}}% free stations save money but may lack amenities like potable water or rinse hoses.

They roam freely and will walk right up to your campsite looking for food. Do not feed, touch, or approach them -- they bite and kick, causing serious injuries every year. Store all food inside your RV, not in exterior compartments they can smell. Rangers issue citations for feeding wildlife. They're beautiful to photograph from a safe distance of at least 40 feet.

The highest-rated is Swallow Falls State Park with a rating of 4.8/5 stars.
