This is a multi-use trail made of crushed gravel. There are no technical features at all, but it is good for a lunchtime lap or for a couple of laps after work. It's also good for taking small kids riding on to get them onto a dirt trail that won't freak them out.
As a loop it's about 2.7 miles, 3.9 if you ride out to each of the two overlooks, and it can be ridden in either direction.
