The trail starts out climbing from the parking lot and heads right at 0.2 miles. Continue climbing, and at about 0.8 miles you'll find another junction. Stay right and the next three miles are a nice combination of climbs and descents, true cross-country style.
At 3.7 miles in, you'll come to a gravel road. You'll also see another trail crossing the road. This is an easy place to get lost as the Flume Trail intersects at this point. The Flume Trail does not allow bikes so you need to turn right on the gravel road and within 50 yards you'll see singletrack veering off to the left of the road. Follow this singletrack to avoid taking a detour on the Flume Trail.
Next, you'll find yourself biking near a church camp. You'll want to stay to your left as you pass two intersections. You'll ride on private land for a short while, stay on the trail. Follow the East Ridge trail signs as you climb out of the church camp. You'll hit doubletrack for a short distance, then at 5.3 miles in, you'll see singletrack off to the right that you'll want to follow.
Pick your way through the next 1/3 of a mile as the trail is a little rocky and technical, descending to another gravel road. Once you see the gravel road, at about 5.6 miles, you'll notice a singletrack trail that parallels the road. Climb this trail for the next mile then, at 6.7 miles in, you'll come to an intersection (the same place you turned right at the 0.8 mile point of your ride).
Jump on the gravel road to your right and take it downhill for about a 50 yards, and you'll see a trail take off from the road to the right. Follow this singletrack trail, crossing a primitive logging road then taking a right turn. After around a tenth of a mile the trail turns left. If you miss this turn you'll end up back on the gravel road within 100 yards. You'll climb with some short descents interspersed along the way until about 8.5 miles in.
Now, it's time for mostly downhill riding back to your car. You'll ride through a super-D course with a few jumps and berms. Cross the road at 10.2 miles, then meet up with the trail you started on. Take a right turn on this trail and ride it 0.2 miles back to the trailhead.
