Sun Valley to Placerville: Epic Road Trip Guide

The roughly 600-mile journey from Sun Valley, Idaho, to Placerville, California, is a trans-Sierra adventure across the Basin and Range province. You leave the Sawtooth Mountains at 5,920 feet and descend into the foothills of the Sierra Nevada at 1,867 feet.

A little-known fact: the route roughly parallels the old Central Overland Route of the Pony Express, and near the Nevada-Utah border, you'll cross the Bonneville Salt Flats, remnants of an ancient lake that covered 20,000 square miles.
