NORTH OF GOVERNOR'S ROAD
The photo above is from the McCormack Trail north of Governor's where it turns east and does a loop, ending back somewhat north, on the Bruce Trail. You can then continue on the trail to the west which loops around to the south and rejoins the Bruce Trail (it crosses a horse pasture which is sometimes closed for hikers when being used by the resident horses, which would mean backtracking)
It is a beautiful and varied landscape (above), yet the last gasp of new sprawl below) is encroaching as building of "Valley Heights" (named after a hill was levelled to build on it) continues.
As new houses obliterate the natural area, former access points to trails are fenced off. The easiest access points to this area are either from the north end of Davidson Blvd where there is a signed Bruce Trail side-trail marker; or from Governor's Road, just west of the Conservation Area main entrance, on the north side. You can also access via Newcombe Road, where a small unofficial footpath follows a fence into the woods.

During the week a city bus gets you near the trails (#52 Delaware "Pirie/Governor's)
I've never seen a map of this trail on the CA web site so I made a little google map with some details.
