The Logan River rises in the Bear River Mountains in Idaho and flows south, then southwest through Logan Canyon and the Wasatch-Cache National Forest to the city of Logan, Utah, in the Cache Valley. In this valley, it joins the Little Bear River a few miles west of Logan and about 5 miles (8 km) south of where the Little Bear River joins the Bear River.

The river is dammed at the 1st, 2nd, and 3rd dams at the mouth of Logan Canyon.
