The Honey Hollow Environmental Education Center is located on the Honey Hollow Watershed in Solebury Township. The Center is open to school and community groups for educational programs throughout the year. Because of the early conservation work carried out by local farmers and the Soil Conservation Service, the entire watershed of the Honey Hollow Creek was designated as a National Historic Landmark in 1969. It remains the only agriculturally based National Historic Landmark in the United States. Educational programs have been conducted here for over 60 years. The land is owned jointly by the Bucks County Audubon Society, Heritage Conservancy and the Crooks family. The Center is operated by the Bucks County Audubon Society.
