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.<br />

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.
Take MN 169 North from 494 to Hayden Lake Road, turn left (West) at the intersection. As Hayden Lake Road curves to the right and turns into Tilden Avenue, you will see a brick maintenance building on the left and Hayden Lake Road continues left at the intersection. Follow Hayden lake Road until you come to the trailhead. There is also a nice paved trail that runs near much of the singletrack.
