About
Patapsco Valley State Park is a large, elongated park following the Patapsco River gorge for many miles through Baltimore/Howard/Carroll counties, with camping in its Hilton and Hollofield areas, both covered under a single address and location (unlike Cunningham Falls and Pocomoke River, this park's camping areas are not separately addressed). No clean total site count is published. 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 $19.50-$20.50/night, Campsite Electric $25.50-$26.50/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).
