I'm always looking for a loop that's kid friendly.  I like the idea of finding a place to ride that has some rougher XC trails, but also has a way you can work an easier loop out that isn't too challenging that my daughter can ride.  Would give us a chance to take the family and ride together on the easier trail, and would still give me a chance ride the full lap while they play.

Post loops that you know of that aren't too technical.  Prefer singletrack, but if you've done a creeper trail or something like that, then post those too.  We've talked about traveling to do one of the rail/trail rides.  Any feedback on those?
