Keep in mind when searching that Avon is in Eagle County. Depending on your difficulty level, check out the Holy Cross trail.

Rusty, if you are reading this, I am still waiting for my $249 refund from 06/2010. Pm me for my address to send the check. Thanks!
Holy Cross is EXREMELY difficult! A Rubicon model will have trouble if not be incapable and a stock vehilce will absolutely not be able to do it.
Colorado is one big "park." A significant portion of our state is public land, open to all as long as you abide by the rules. There are enoug old mining roads that even a resident could spend a life time attempting all of them.
I suggest looking up "Colorado Backroads and 4-Wheel Drive Trails" (ISBN 10: 0-9664976-6-x or 13: 978-0-9664976-6-3) by Charles A. Wells. It is a thorough book of Colorado trails.
I also suggest looking up the National Geographic maps for the area. They will show foot trails, vehicle, multi use, etc... For Avon you are looking at map 108 or 121. They are tear resistant and water resistant. Colorado trails are big enough to get lost, turned around, and generally screwed...
You can PM me as well. How is the AVE Rubi setup? tire size? Trough Trail is a fun trail. You can make it in a setup Jeep. I've lived in the Vail area my whole life, I'd be happy to show you around if I'm in town, hiking, 4x4ing or biking.
