About
Greenbrier State Park, along the Blue Ridge near Boonsboro, centers on a 42-acre spring-fed swimming lake. 165 campsites (125 basic, 40 electric) across several forested loops, with bathhouses and a dump station. Golden Age Pass holders get half-price camping Sunday-Thursday. Reservable through the Maryland Park Service's own ReserveAmerica/Aspira contract, hosted at parkreservations.maryland.gov (not a reserveamerica.com subdomain, though it runs the same underlying platform - confirmed live, "Powered by Aspira").
Fees
Campsite Non-Electric $21.50-$22.50/night, Campsite Electric $27.50-$28.50/night. Displayed rates are the vendor's own published BASE rates and do NOT reflect holiday/weekend/residency surcharges or a pet fee (Maryland applies these as add-ons rather than publishing a separate resident/non-resident base rate the way some other states do). Pets allowed in the Cedar and Dogwood camp loops only - not park-wide.
