Charles County, Maryland

Southern Maryland’s got a gem called Charles County, about an hour’s drive from DC. Its western border is the Potomac River.
You’ll find some serious natural beauty here. We’re talking 300 miles of shoreline and tons of parks. Fishing, boating, hiking. Take your pick.
The county seat is La Plata. It has a small-town vibe but don’t let that fool you. It’s not all perfect though. Traffic can be a pain, especially for folks commuting to the city. But for many, the trade-off is worth it.
