This is a great network of short trails for hiking with your kids. We have gone several times with our 3 1/2 year old daughter and she loves it and does great. The provided map isnt great, but they are marked pretty well with permanent markers instead of blazes.
I walked with a boy scout troop and we walked 14 miles in and out. I am assuming out walk was longer than listed because it is part of a larger greenway. It has plenty of rest stops, mile markers and a bathroom at the beginning and about 4 miles in near the Jamestown golf course. I am walking this again with my small children (but not 14 miles.. maybe 6)
It's a great collection of trails if you just want to get a good run in after work! I pretty much go daily. I love the white and blue trails, which run a good distance beside High Point lake. Pretty scenery. I've run into a few deer and turtles on the trail, so it's always exciting. Always sounds serene, which is ideal. You do have to leap over a few trees now and then, but I think that's the fun part. Just don't trip and fall! And there is also a pretty good variety of incline/decline. It's not flat all the way through.
Also, all of the trails are pretty much lost in the trees and shady (so cooler)--which is perfect when it's ridiculously hot and sunny!
There are a decent number of runners that use the trail daily, but there are also couples who just come to slowly hike, walk it, if you want a less strenuous evening. There are also a few shorter trails and a paved "Greenway" trail for bikes or those who'd rather walk on pavement.
