Year-round camping in Maryland
49 Maryland campgrounds are listed as open year-round by the managing agency, the state park system or OpenStreetMap. We found a published season for 60 of the 152 Maryland campgrounds we list; the rest are marked "Season not listed" rather than guessed.
"Year-round" often comes with winter limits: some loops close, water is shut off, or bathhouses are winterized. Where the source says so, it's listed below. Weather and road closures can still close a campground, so check the official page before a winter trip.
