The Route 66 Trail was highly enhanced in 2017 and is now 6.6 miles long in a lariat loop configuration. Easy to intermediate trails are located to the South. Intermediate to advanced trails are located to the North, with the Northern "Chicago Loop" containing many uphills and advanced features.
Along the way, you will find flowing singletrack, challenging features, and a number of heart pumping uphills.
You will find many unique log features, a challenging gravel mound, cool bridge, bike moguls, fast downhills, and a woodsy rock garden.
The "Chicago Loop", located to the far North, is mainly for stronger riders and can be ridden in either direction.
There are multiple trailheads along the way but starting at picnic area 3 on Park Road puts you right in the middle. Go North for really cool features and "Chicago Loop" and head South for an easier ride.
