Jenny Jump State Forest
Jenny Jump State Forest, Mountain state forest in Warren County, New Jersey.
The 4,466-acre forest extends along Jenny Jump Mountain ridge, reaching elevations of 1,112 feet with glacial boulders and rocky outcroppings throughout the landscape.
The forest area contains remnants from the Wisconsin glaciation period of 21,000 years ago, when mile-thick ice sheets from Canada shaped the current terrain.
The Greenwood Observatory, constructed in 1995 by the United Astronomy Clubs of New Jersey, provides public stargazing sessions and astronomical education programs.
The forest maintains 14 miles of hiking trails, 22 camping sites, and 8 shelters, with access to Ghost Lake for fishing and Mountain Lake for swimming.
The forest offers some of the darkest skies in New Jersey, making it a preferred location for astronomical observations and astrophotography sessions.
