Horsepen Run Stream Valley Park
- Nature reserve
- Regional draw
- Floris
Horsepen Run Stream Valley Park protects a creek corridor and wooded open space in the Floris and Herndon area.

The stream-side landscape provides a quieter nature setting among surrounding neighborhoods and transportation routes.
Use county trail information and posted public entrances rather than crossing neighboring private property. Routes can be uneven or muddy, and creek levels change after rain. The photograph shows Horsepen Run within the wider corridor rather than a staffed visitor facility or a promise of a continuous easy trail through every park parcel.
