(Directions: Many access points: Hydro Corridor, Terraview Crescent, Rodgers Road, Kirkby Crescent)
This basically uses part of the different trails I have described in Preservation Park. Starting at the Hydro Corridor, you turn left immediately after the fenced pond (and before you get to the creek). This is the green trail. The trail will follow the fence, then curve around the subdivision and continue for the most part on the outside of the woods. At one point you will be walking directly behind people's houses and then through an open field which borders Kortright Rd. You will have to look for the path here as there are different ways to continue parallel to Kortright, until you come to the trail runnning from Kortright Rd. itself (at the traffic light between Ironwood and Edinburgh) which will take you to the Rodgers Road trail (the green trail).
You follow the green trail to where it meets the red trail (Terraview trail). Follow the instructions for this trail until you come to the branching of the path, one way back across the woods to the business park or south on the yellow trail to the south end. You come back up the outside of the park to the pond. From here you can continue north on the yellow or black trail back to the Hydro Corridor (the black trail at the Hanlon) then back up to the parking lot.
Obviously you can do many variations of this route starting at many different places. And you will find many other trails not marked on my map.
