Located only an hour from Boise, Summit Flat Road (FSR 380) stretches from just north of Idaho City on its eastern end to the historic mining town of Pioneerville on the west. Pioneerville was one of the main mining towns during the Boise Gold Rush of 1862.
This tree-lined dirt and rocky road traverses the Boise National Forest, offering spectacular views of the rugged Sawtooth Mountains to the northeast and the Boise Mountains to the south. Be sure to take the short spur up to Pilot Peak; it offers the best views, and the spur is located at the southeastern end of the trail. Grimes Creek runs alongside most of the trail.
Towards the east of the trail, there are bumpy rocky sections with a mild incline that will keep your speeds low, but any high-clearance vehicle can make it. 4WD is recommended but not necessary. Along the drive, you will find only a few pullouts suitable for camping.
