The river arises at 2,548  m in the White Mountains at the confluence of the West Fork Colorado River from the left and the East Fork Colorado River from the right in the Apache National Forest near Greer in Coconino County . Immediately afterwards the river is dammed to the artificial lake River Reservoir . It flows shortly to the northwest, then to the northeast to Springerville . The Nutrioso Creek flows here from the right , before it now mostly flows to the north-northwest, while US 189 follows a few kilometers away .

The Little Colorado River is dammed 16 km south of St. John's to Lyman Lake . After the reservoir, it reaches St. Johns and passes under US 191 before entering the Hunt Valley . It crosses under US 180 twice before reaching Holbrook .

The river flows at 823  m about 115 km north of Flagstaff in the Grand Canyon and the Grand Canyon National Park from the left into the Colorado River.
