Patapsco Heritage Greenway

Working to advance the interests of the Patapsco Valley for all who share it.

Maryland’s Heritage Areas allow us to explore parts of Maryland in a truly unique way. Within the Heritage Areas, individuals, businesses, non-profits, and governments form partnerships to preserve the best of Maryland’s historic sites and towns, unspoiled natural landscapes, and long-lasting traditions.

In 2015, Patapsco Heritage Greenway celebrated a major milestone when the Patapsco Valley became one of Maryland’s 13 certified Heritage Areas. This designation depended upon the unanimous approval of the Patapsco Valley Heritage Area (PVHA) Management Plan by both the Baltimore and Howard County governments.

In 2020, the PVHA boundary expanded northwest to extend from Granite and Marriottsville as well as southwest to the Baltimore City-County line including Daniels, Ellicott City, Oella, Catonsville, Ilchester, Relay, and Elkridge.


In 2025, the Patapsco Valley Heritage Area lies at the heart of a network of protected lands along the Patapsco River, representative of Maryland’s Piedmont forest and industrial heritage. Natural processes, natural beauty, and history combine to create a unique opportunity for neighboring residents and visitors from across the state and beyond, to understand and enjoy Maryland’s most dramatic river valley. Through the efforts of many partners, the public appreciates the significance of the valley’s heritage, understands its history, and enjoys the experience it has to offer


As the non-profit managing organization for the Patapsco Valley Heritage Area (PVHA), Patapsco Heritage Greenway (PHG) is dedicated to preserving, protecting, interpreting, and restoring the environment, history, and culture of Maryland’s most dramatic river valley for all.
