Major trail complex with lots to do. Trail maps are available at stations and you will need to pay a $5 fee for parking. The trail is about 5 miles long with little technical challenge but a great place for a fast workout. In April of each year it is home to the Fat tire Classic race, more info can be found at route 66 race series website.
Winding Trails is easily accessible from Interstate 84, exit 39 (Route 4, Farmington). Head straight off the exit and travel west on Route 4 for 2.2 miles. Turn right onto Devonwood Drive and then turn left onto Winding Trails Drive.
