Favorite NJ Reservations with Fun Outdoor Kids' Activities and Hikes

Looking for fresh air and family adventure? Head out to explore one of New Jersey's "reservations"—forested nature preserves that are like mini state parks. Hidden along river banks and tucked into woodlands, these green spaces are ideal for family hikespicnics, and biking. You can bring binoculars to spy on colorful birds or wear boots to let the kids muck around with turtles and frogs.

Some reservations have marked trails, education and nature centers, playgrounds, and restroom facilities, while others are a bit more rugged, with "carry in/carry out" policies—meaning not even trash cans are provided.

We've rounded up 10 reservations with a variety of offerings. Read on to find the best spot for your next outdoor adventure!
