Gambrill State Park sits on the wooded ridgeline west of Frederick, Maryland, and its campground occupies the Rock Run area with 34 sites spread across a forested loop. Sites vary in character: numbers 8 through 11 sit on a more open field with smaller trees, while sites near the creek allow campers to pitch a tent within earshot of the water. Electric hookups are available on most sites, with a 31-foot maximum length, though at least one reviewer notes that site 13 "just fit" a 30-foot trailer, so rigs on the longer end should plan carefully.
The campground draws a consistent crowd of campers from the DC and Baltimore corridors, given its location roughly an hour from both cities. That convenience comes with a trade-off: a low road noise hum is audible from some sites when conditions are quiet, and the loop offers limited seclusion between neighbors. Park staff make frequent rounds, which reviewers generally appreciate. Cell coverage is workable; one camper recorded 63 Mbps down on T-Mobile mid-day on a Friday.
Trails fan out directly from the campground and connect to the surrounding Frederick watershed. Melissa C. notes that "every hiking trail except for the white trail allows mountain biking and horseback riding," and the park also draws wildlife, including foxes, bears, and occasional bobcat sightings. Camp Misty Mount sits a few miles northeast for campers wanting a second nearby option. Cunningham Falls, Catoctin Mountain, and Greenbrier State Park with Appalachian Trail access are all within a short drive, making Gambrill a workable base for a multi-day itinerary.
The campground runs April through October, with reservations available. Rates range from $18 to $50 per night depending on site type. There is no camp store on site, but a full grocery store is a short drive away, and firewood bundles are sold near the bathhouse for $5 cash. No dishwashing station exists at the bathhouse, so campers should bring their own tubs. Showers run hot. Pets are welcome throughout, including in Cabin 18.
Campers who want a low-key overnight close to the mid-Atlantic corridor, with solid facilities and trail access right from camp, will find Gambrill worth a reservation.
