Part of Maryland's Patapsco Valley State Park, Hollofield Area Campground sits along 32 miles of the Patapsco River corridor within reach of Baltimore and Washington D.C. This state park campground operates seasonally from April through October, offering both electric and primitive sites arranged in two concentric loops. Access requires navigating through residential areas on what reviewers describe as rough roads, with an 11-foot height restriction on the eastbound approach bridge.
The campground's inner loop contains electric sites with 20 and 30-amp hookups, though campers note these spots sit closer together than the outer primitive loop. "The sites feel private," observes Jennifer S., despite the proximity to neighboring areas visible through bare trees in early season. Dense forest canopy provides shade during summer months, while aircraft from nearby airports create intermittent noise overhead. The single bathhouse serves both loops and shows its age, though campers consistently report it stays clean.
Hiking trails lead directly from campsites down to the Patapsco River, where swimming and fishing are possible. A natural playground of large rocks and fallen trees sits within the camping area, while a traditional playground operates near the park entrance. The campground fills completely on weekends but remains nearly empty during weekdays. Camp hosts sell firewood for $5 per milk crate, and a dump station serves RVs up to 24 feet in length.
Campers should bring their own firewood is prohibited, and alcohol restrictions apply except inside RVs. Cell service works well with major carriers, providing reliable connectivity. "You can even swim in this river," notes Travyl Couple !., highlighting the recreational opportunities beyond the campground itself. The location provides budget-conscious access to Baltimore's attractions while maintaining a forested camping experience just minutes from major highways.
