The Yellow Grade road is the easiest way to get to Cerro Gordo. It is steep, but maintenance by Inyo County makes it suitable for passenger cars when the weather is good. At the same time, the possibility of bad weather and the steepness of the grade mean that a 4WD just makes more sense. On the climb up, we shifted into 4-Low to make life easier and cooler for our transmission. Cerro Gordo owner Mike Patterson told us that winter storms and washouts sometimes make this road completely impassable.
