Sterling Forest State Park comprises 21,935.08 acres of nearly pristine natural refuge amidst of one of the nation's most densely populated areas, a remarkable piece of woodland, a watershed for millions, and a tremendous outdoor recreation area. This unbroken deep-forest habitat is important for the survival of many resident and migratory species, including black bear, a variety of hawks and songbirds and many rare invertebrates and plants. Hunting, fishing and hiking opportunities are available.

To help disseminate knowledge about Sterling Forest's environment and history, the commission built the US Senator Frank R. Lautenberg Visitor Center. The visitor center overlooking Sterling Lake features exhibits about the local environment as well as an auditorium for related presentations.
