Jenny Jump State Forest is located in Warren County along the stunning rolling terrain of Jenny Jump Mountain Range. Panoramic vistas of the Highlands and the Kittatinny Mountains and Valley to the west, and scenic views of the Great Meadows in the east dramatically greet the visitor who climbs the narrow path leading to the top of Jenny Jump Mountain. Rocky outcroppings and boulders line the trail - evidence that great glaciers once covered what is now known as Jenny Jump State Forest.

Effective November 8, 2008 through March 31, 2009, the administrative office at Jenny Jump State Forest will be open Monday - Friday. The forest will remain open seven days a week for both passive and active recreation. Administrative office hours will resume seven-day scheduling on April 1. Camping is still available on weekends with advance reservations.

Through the Carry-In/Carry-Out Program you can help us keep your parks clean and beautiful by carrying out the trash you carry in. Bags are provided throughout the site. Thank you for your cooperation and remember to recycle.

Glaciers receded from Jenny Jump Mountain near the end of the Wisconsin Ice Age, about 21,000 years ago. Exceeding a mile in thickness, the ice advanced southward from Canada, gouging out valleys and rocks from mountain tops, incorporating sediment, boulders and debris into its mass. Much of this debris was carried by the glacier or transported by meltwater to the edge of the ice where it was deposited in huge ridges called moraines. The dramatic effects of this can be seen in Jenny Jump State Forest.

The United Astronomy Clubs of NJ (UACNJ) leases property from the NJ Department of Environmental Protection and in 1995 completed the Greenwood Observatory. The UACNJ provides public programs on Saturday evenings from April through October, from 8:00 to 10:00 pm, at which an astronomy presentation is followed by an observing session, weather permitting.

Six miles of hiking trails and three miles of hiking and mountain bike trails offer magnificent views of the mountains and scenic Mountain Lake. The Summit Trail, at an elevation of 1,090 feet, offers a view of the Pequest Valley.
