In 1862 an emigrant party asked guide Tim Goodale to lead them west from Fort Hall on the cutoff pioneered by Jeffrey. They hoped the alternate trail would enable them to reach the Salmon River gold fields more directly. Goodale succeeded in leading a group of 1,095 people, 338 wagons, and 2,900 head of stock safely from Fort Hall to Boise. In 1863, seven out of every ten wagons en route from Fort Hall to Boise took Goodale's Cutoff instead of the main Oregon Trail.
A network of primitive roads through the park service and Bureau of Land Management (BLM) portions of the preserve offers backcountry driving opportunities and access for those with high-clearance, 4-wheel-drive vehicles.
