Start off on the Bell Rock trail, go about 1.25 to 1.5 miles untill you locate the tunnel under Hwy 179 ( kinda hard to find without a map ). Go through the tunnel to start this fast rolling trail with some good sized drops on a few of the down hills.
On Hwy 179 across from the Bike N Bean bike shop in Oak Creek, you will find the Bell Rock trailhead. Stop at the bike shop for maps and a cool 3D Topo style map of the area with the trails marked. Get a preride java fix or bike adjustment while you are there.
