when I'm investigating a potential new trail I use google street view. I know the Google cam-car won't be driving down the trail, but I look for paved road intersections that the Google car has gone down. then I zoom in on the intersections & turn around to look down the trail. do it as much as you can at as many intersections as you can & you can learn a lot
you said you went to their website. did you also check out traillink?

they usually have lots of first hand reviews, pictures & info on parking, restrooms, riding surface & maps!
it looks really nice, maybe Wifey & I can try some of it when we visit her Mom in the spring
