The Lois Y. Green Conservation Park consists of a 200-acre parcel that Lois Y. Green gave to M-NCPPC in 1975 and an additional dedicated stream buffer area of 50 acres. The 250-acre conservation park is located adjacent to the Montgomery County Airpark and is surrounded by residential development.

Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are “Shared by All” trails which includes hikers, bikers and equestrians.

Use: Hiking, Biking, Equestrian

Length: 3.8 miles of natural surface trails

More Info: When Mrs. Lois Green donated the park to M-NCPPC, she specifically directed that the park, “shall be used as an open space, for parkland, and for recreation in such a manner as to evidence the conservation of soil, water, woods, and wildlife… and shall be maintained essentially in its natural condition…” Today the Park is a remarkable oasis in a highly developed area of the County. Even though it lies beneath an airpark flight pattern, the expanse of the park’s grasslands, topography, tree-lined stream, large ponds, wetlands, and woodlands create a feeling of respite and retreat.

Water & Restrooms: Drinking water and restrooms are not available.

Access and Parking: 8711 Snouffer School Rd, Gaithersburg, MD 20879. The main park entrance is from Snouffer School Rd.
