Patapsco Valley State Park · Baltimore County, MD
Patapsco Valley — Daniels Area
Upstream gorge of the Patapsco with ruins of the old Daniels mill town. Standard riverside loop to the dam ruins; longer ridgetop connectors add a powerline-cut climb if you want a 4–5 mile day. Quieter than the Avalon area; bike-legal on designated trails only (yield to anglers along the river).
