This is a great time of year for the hike -- saw my first NJ butterfly of the spring and quite a few birds there last Thursday, and heard Spring Peepers all three trips. Lots of neat mushrooms, rocks and other stuff along the way
The 1.5-mile hike to the summit is strenuous. It took me 30 minutes to reach the top, and I was walking briskly with no stops. I would bring water and a snack, too. It's a great workout.
You begin at the start of the Red Trail at the Red Trail Parking Lot (below left) at William Paterson University and hike to Marry Me rock at the summit (below right).
That's Manhattan way in the distance. The views from the summit are great.
