Let's try the trails at Mallard Lake. I've looked around here before but haven't hiked the trails. The loop is small but going up and back on all the side connections should be about 4.5 miles.
The entrance is at Schick Road and Mallard Lane just slightly west of Gary Ave.
Enter at Mallard Lane (go north) and the parking lot is at the end of the road.
This map should take you to the entrance:
