Anchor the day around Cascade Falls

For one day in Patapsco Valley State Park, make Cascade Falls the non-negotiable, add Orange Grove swinging bridge only if the first stop runs clean, and keep 200-plus miles of trail across multiple areas as the flexible finish.

Car strategy
Patapsco Valley wraps around the southwestern Baltimore suburbs, with separate entrances for the Avalon, Hollofield, Hilton, McKeldin, and Daniels areas off roads like Route 1, Route 40, and Marriottsville Road, near Elkridge, Ellicott City, and Catonsville.
Car strategy
A car is essential, and because the park is split into distinct areas, plan your route to a specific entrance rather than the park as a whole.
Local movement
The popular Avalon area, home to Cascade Falls and the swinging bridge, can fill and close at capacity on weekends, so arrive early.
Pair this with lodging: choose the base that keeps the reservation or permit pickup from becoming the hardest part of the day.
