Chuckwagon is a 11 mile hiking trail in Sedona, Arizona.
Drive up Dry Creek Road (off 89A at the west end of Sedona) to the junction with FR --- (which goes up to Devils's Arch and Vultee Canyon). Turn onto this dirt road and park along the shoulder. Note: at the end of 2012 a major trailhead construction project was underway a quarter of a mile up this road so you may not have to park on the dirt.
