Ellicott City High Intensity Patapsco Valley State Park
It's been called the Moab of the East for its variety of world-class trails and terrain. The park offers biking in three sections—Avalon, McKeldin, and Hollofield—along the Patapsco River. The hardcore Avalon area features single-track trails with steep climbs, fast descents, and lots of rocks and exposed roots for brain-jarring excitement. Log ramps, sharp switchbacks, tunnels, rolling hills, open fields, and water crossings add to the insanity. For more, visit the park's website.
