This is a great trail for the whole family. I saw fathers and grandfathers out with their children and grandkids showing them the ropes of Mountain Biking. This trail was completed this summer (2011) and doesn't have a lot of technical features but it rolls quickly and in ome sections your bike can get away from you if you carry too much speed around the corners. Just be careful as there were children out on BMX bikes and geared 20" mountain bikes as well.
I use the beginner loop as a warmup (about 2 1/2 miles), and then ride on to the intermediate loop which eventually connects to the advanced loop. To hit every bit of singletrack in a day you will need to re-ride a few sections but it is all very fun.
Review: My favorite trail system in the metro area. Good variety difficulty and scenery, well designed singletrack, fun features. I've seen deer on the trails often. Only thing to be aware of is there can be groups of newbies going slowly.
Review: Awesome trial for winter fat biking. Very smooth flowing. Love the roller coasting section towards the end. Climbing is not as intense and doesn't have as much variety as Lebanon does.
Since all obstacles have a by-pass route the intermediate section is like an advance beginners; no bumps just sharp flat corners and mild up/down hill.
