South West Association of Mountain bike Pedalers, or SWAMP. They have an excellent web site which is a great resource for trails in the area. This particular trail network has two sections, a 7-mile and a 5-mile, both of which a pretty similar in that they are flat and non-technical. Despite the fact that the trails are flat and easy, they are still quite fun, with lots of twists and turns and great scenery. I think SWAMP did an excellent job with these trails as they are all well marked, with the possible exception being at trail marker 2 where you have to cross over the paved path. There's a small (easy to miss) arrow that points to the right, but looking directly across the path there's a trail, so I flew straight across and it took me a bit to figure out what I had done wrong.
Anyway, I enjoyed the trails enough to make the trek back a second day with my wife because I knew she'd have fun too. And she did.
It was $2 for park access and there are bathrooms and other facilities near the parking area, including a bike wash station at the trail head... that's pretty awesome!
