This road will take you right to the Observatory (top of the hill).
From 78 East use Exit 17.
From 78 West use Exit 16.
Then take Route 31 North. Approaching the second traffic light turn right onto Route 513 North (to High Bridge), right at the end of the ramp to head north and go through High Bridge. Note, 513 North turns sharply right at the train station just before Main street, then again at the end of Main St., which is only a few blocks long. Moments after turning off Main go left at the church (which keeps you on 513 North). Just over a mile later look for a small brown sign on the right for the NJAA Observatory. The next left is the south entrance to Voorhees State Park onto Observatory Road. The observatory parking lot is about 1/2 mile up on the left.
From 513 Southbound
Coming down 513 from the south (or east), about 5 minutes after you pass through Califon you will see Voorhees High School on the left. Directly across from the school entrance is the main park entrance. KEEP GOING!! 1 mile further down the road is the entrance you want, there is a small brown “NJAA Observatory” sign on the right, the entrance is just after that on the right.
