Getting There & Parking
Understanding how to get to Jenny Jump State Forest is straightforward, as it's conveniently located in Warren County, New Jersey. The physical address for the park is 330 State Park Rd, Hope, NJ 07844.
For those traveling by car, we recommend the following directions:
- From Interstate Route 80: Take Exit 12 (Route 521-Hope) and head south on Route 521 towards Hope for approximately 1.2 miles. Turn left at the traffic light in Hope onto Route 519 North. After about half a mile, take the third right onto Shiloh Road. Continue for roughly 1 mile, then take the second right onto State Park Road (look for signs). Follow this road up the mountain; the park entrance will be on your left.

We advise using 399 State Park Road, Great Meadows, NJ, to get directions to the driveway leading to the observatory. The observatory itself is located at 333 State Park Road, Great Meadows, NJ.
Regarding Jenny Jump State Forest parking, there are no entrance fees for the state forest itself, which means parking is generally included with your visit. Designated parking areas are available throughout the park, particularly near trailheads, picnic areas, and the campground. We always recommend arriving earlier in the day, especially during peak seasons or weekends, to secure the best parking spots and avoid potential crowds.
