Blue Mash Trails

Blue Mash Trail Map Locator Description

The Blue Mash natural surface trails are located in the buffer area surrounding the site of the former Oaks Landfill, near Mt. Zion.

The Blue Mash Nature Trail commemorates the pre-Civil War settlement called Blue Mash inhabited for many years by freed slaves. "Mash" was the colloquial pronunciation of marsh. Before emancipation, the Blue Mash swamp was known to have been a hiding place for fugitive slaves.

Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are "Shared by All" trails which includes hikers, bikers and equestrians. Additional information about permitted uses of Park trails is available on our Trail User Information page.
