Trails: 18.5 miles of trails

The network of trails makes the center's fields, woodlands and streams accessible to both students and the casual visitor. These facilities are for use by hikers, all-terrain bicyclists, horseback riders and cross-country skiers. We suggest that non-hunters wear blaze orange during hunting seasons.

Jacobsburg was dedicated as an environmental education center in October of 1985, and is one of four environmental education centers operated by the Pennsylvania Department of Conservation and Natural Resources, Bureau of State Parks. Through its environmental education programming at centers and state parks, the Department aims to help develop a citizenry that is aware of and concerned about the environment and its problems, and also has the knowledge, attitude, motivation, commitment and skills to work individually and collectively toward solutions of current problems and the prevention of new ones.

The Jacobsburg environmental education program consists of a variety of quality programs including; student field learning experiences, Youth Environmental Learning Series, Environmental Forums for high school students, Conservation Leadership Schools, the Bureau's Watershed Education, school site and curriculum development, and numerous in-service and pre-service teacher workshops focusing on problem-solving for a variety of environmental issues and natural history. The center's program staff also offers community programs and supports ecological research, in addition to assisting in developing regional and statewide programs that serve educators and other Bureau and Department program and staff needs.

Educators and school groups wishing to participate in a learning experience at Jacobsburg should contact the center office for program scheduling and reservation information.

The Jacobsburg National Historic District lies almost entirely within the boundaries of Jacobsburg Environmental Education Center. The district is on the National Register of Historic Places and its story is intertwined throughout the early development and growth of our nation. The history of Jacobsburg focuses on the Henry Family and their small arms industry; an industry that played a key role in the American Industrial Revolution.

The first of the Henry gunmakers, William Henry I, opened his gun factory in Lancaster, Pennsylvania, in 1750. He became Armorer for the Braddock Campaign of 1755 and for the Forbes Expedition of 1758. William Henry II established a small gunmaking shop in Christian Springs near Nazareth in 1778. In 1792, William Henry II purchased land at Jacobsburg from the heirs of Jacob Hubler, who in 1740 founded the community from which Jacobsburg draws its name. Henry II built a gun manufactory at Jacobsburg. A few years later, he erected a forge (bloomery) to supply the gun factory with iron to manufacture guns. In 1812, a larger manufactory was built in nearby Boulton in order to accommodate large government firearms contracts.

Three succeeding generations of Henrys produced small arms at Boulton until the late 1800s when competition from small arms companies using mass production techniques made the Henry's handcraft technology obsolete. It is still remembered, however, that the Henrys not only produced firearms for all of our nation's major conflicts from the Revolutionary War through the Civil War, but that they were also the primary suppliers of rifles for the largest American business enterprise of the early 19th century, John Jacob Astor's American Fur Company. The Henry firearm became the most prominent weapon of the western frontier due to its durability, accuracy and relatively low cost.

Only the foundations remain from the colonial village of Jacobsburg. The Jacobsburg Historical Society administers and operates one of the most significant and picturesque historic sites in the Lehigh Valley. The Henry Homestead, built in 1812, lies on a beautiful tract of land leased from the Bureau of State Parks. In 1989, the society also acquired the John Joseph Henry House from the estate of Mary Henry Stites. The house, built in 1832, is surrounded by 23 scenic acres.
