Wide open fire/access dirt roads, one patch of rocky road, easy climbs, old quarries with strange mazes built by park visitors in the bottom of 'em.

Trail Directions
From Co Co Co and points east, take 24 west, exit Fish Ranch Road, go right on Fish Ranch to Grizzley Peak, left on Grizzley Peak until it ends at Skyline. You've been driving on the west side of Sibley at this point. The staging area is left on Skyline just 150 yards or so. From the staging area, ride the road on the right side of the exhibit building, and bear left when it forks. The road turns to dirt, and after 50 yds., you'll come to a cattle gate. Past the Cattle gate, you are there!

Summary:
I agree with above posts, though if you want to bomb down a double track with a few stream crossings, a few small jumps, start to the left of the bathrooms going downhill (not immediately to the left, but more of a hard left heading downhill. I started with this and the elevation drop at least let me get a workout on the way back up.

Recommended Route:
Start with hard left going downhill from parking lot (this avoids any bouldery areas.

Other recommended trails in the same area:
Joachim Miller is my go to for short fun, Eastridge/Westridge for more cardio.

Summary:
A fun place to ride around every once in a while, but nothing spectacular. There's two main problems with this "trail".

Problem #1: There isn't really any trail, it's just a few intersecting fire roads, none of them even a mile long. You can't really do a big loop, or even an out and back. Instead you just sort of ride around exploring the nooks & crannies. It would be good for introducing your girlfriend to mountain biking except...

Problem #2: Lots of softball and football sized rocks on the trail make it bumpy and unpleasant at the beginning. Once you get away from the cattle gate and into the park it's fine.

The good news is:

There's some nice views and the little stone labyrinths are pretty nifty.

The main reason I keep coming back here is that dogs are allowed off leash in this park and it's not too crowded. This makes for one of my favorite places to just putz around on my bike while the dog gets to chase at my heels.

Recommended Route:
From the parking lot, the trailhead is to the right of the bathrooms. Go past the gate and follow the paved road about a quarter mile up. Follow the fork to the left. You'll go through a cattle gate and that's the entrance to the park. From there, it doesn't really matter where you go, just explore. You can't really get lost here, it's not that big. Try to find all 3 labyrinths and make sure you leave a little trinket in the center.

Other recommended trails in the same area:
East Ridge & West Ridge Trails are where I first learned to ride. Still love-them. Chabot has some nice long trails as well.

Summary:
Was I missing something? This "trail" was not worth the drive (15 minutes). The trail is interesting in the beginning, there are a lot of medium-sized rocks on the fireroad, but it then turns into a low-grade gravel fireroad to the bottom, where there is nothing but a tractor tire and an empty field. I can imagine the tire would be fun if you're into trials...The quarries are not what I expected, very small. There are some pretty weak 1/4 long singletrack trails above the quarry (by the bathtub), and it is quite possible to fall off the cliff. I think this area would be okay when the backside is dry (past the cattle-gate).

Recommended Route:
From the lot, right around the visitors center, left at the first Y, left at the second Y and go through the gate.

Other recommended trails in the same area:
There is potential for interval training as someone said, but its pretty boring- go to the bottom; ride up to the top; repeat. You'd be better off on pavement with a road bike.

Summary:
This is a really easy ride, so you have to find things to do to make it fun. Riding down into the quarries qualifies. I usually use this ride to practice handleing because of all the baseball to football size rocks and cow pies.
Also, if you don't have full suspension, or a seatpost shock, you're in for a rough time, especially on the first half of the trail. I't more fun to bike up tunnel, especially because you can use your highest gear the entire way down tunnel.

Recommended Route:
Everything, especially the quarries. Try going up Tunnel road, even though it is a road, it makes the entire ride more of an intermediate one.

Other recommended trails in the same area:
Anything within five or ten miles, especially Juaquin Miller and Redwood.

Summary:
Loose rocks, tons and tons of cow sh#t, steep drop offs

Recommended Route:
Go way out in the back and hike some hills and you will find some downhills that will make you wet yourself!

Other recommended trails in the same area:
Big Trees (warning big trees trail is now illegal...but that shouldn't stop us)
