Idaho State Highway 75 (SH-75), also known as the Sawtooth Scenic Byway, transverses the valley's entire length. SH-75 enters the valley from the south at Galena Summit and exits to the north near Stanley. SH-75 was formerly designated as U.S. Route 93, which is now routed through Arco.
Sawtooth Valley contains several large lakes in the SNRA, including Redfish, Alturas, Pettit, and Stanley lakes. Valley floor elevations range from just under 6,300 feet (1,920 m) near Stanley to over 7,500 feet (2,290 m) below Galena Summit. Elevations along the valley's borders reach 11,815 feet (3,601 m) at Castle Peak in the White Cloud Mountains to the east and 10,715 feet (3,266 m) at Thompson Peak in the Sawtooth Mountains to the west.
