We started at the Pleasant Valley Road entrance (thanks JPO), which is about 3 miles up from Rt. 29. If you want to start at a higher elevation and ride down (then back up again to your car), this is the entrance to start from (conversely, if you want to ride up first, then ride back down, start at the Fiddler's Creek Road entrance). The white trail (Ridge Trail) was nice...little rocky, but nice, long downhills and uphills - it's about 2 miles one way.
The orange trail (Copper Hill Trail) was overgrown, steep, very rocky, and has it's share of obstacles - parts of this trail are basically unrideable. The Creek Spur (one of the blue trails) connects Fiddler's Creek Road to the orange trail. This trail is very tough - good for hikers and equestrians - don't bother unless you feel like carrying your bike or breaking your neck. We did not have time to explore the other trails.
Interesting note: There is a clearing close to the visitor's center (end of white trail) with a great southward view of the Delaware River, Trenton, and the giant landfill down by Tullytown - probably great for stargazing and photography.
