From the parking lot, the trail head is marked just left of the fenced-in dog park next to the woods. This is a single complete loop that runs roughly 3.25 miles. Like many trails in the area, people try to add shortcuts to the original trail layout. If you stick closer to the trail, you shouldn't have a problem. There is a good bit of climbing in the beginning with tight switchbacks, however is then rewarded with fast descents with climbs. The trail is an average of a 1-2 ft wide. There are log crossings in the trail where you can get a little air because you will already be going fast downhill. I recommend learning the trail a bit before you get too comfortable. Not ideal for beginners.
Note: Most people in the area agree that this is not a trail for beginners. It takes skill and endurance to run the full loop without stopping. The climbs and descents are steep and fast. You don't have a wide trail to begin with. This info serves as a more accurate description of this trail system. Thank you.
