Taft is about 5 1/2 miles EAST of LookoutPass. Take I-90, exit 5, down the road department gravel pit, with a "sorta" big brown building. (Red arrow). It comes up quick from the hyway, so watch out for the exit. You can unload here. The trail runs along a creek, paralleling I-90 for a little while. If you go East about 1/8 mile there's a bridge crossing that creek. From there you can go either South (Dominion?) or East (Taft?). The trails wind around the hills for about 5-10 miles and meet at an intersection up high. This is a general meeting area for different groups. There are a few play areas along the way. On the South side of this area are some nice tree areas to play in as well.
This second map of the Taft area might show a little better, and possibly that's the trails you see leaving the I-90 area. It's not completely clear to the Author, hopefully a better (trail) map can be obtained and posted here. There's some green arrows to get started in planning your way.
