At 325 acres it offers a little bit of everything, dense forest stands, semi-precious stone mining sites, abandoned quaries, ledges and large glacial erratics.
The trails are all natural surface ranging from old woods roads to sinuous singletracks. In all you'll find just under 8 miles of trails. They are very well maintained by the City. You'll notice many drainage features to keep water off the trails. There are long armored "turnpikes" to keep you high and dry in perpetually muddy areas. There are even benches every half mile of so in case you want to stop and take a break.
For a first ride I'd suggest following the blue blazed trails in a clockwise direction. This will maximize the downhills, although the trail is fun both ways. Then I'd suggest filling in the middle by doing all the red blazed trails.
