California has more of what a driver wants than anywhere else in the country: coastal highways, high Sierra passes, and canyon roads that start minutes from Los Angeles and the Bay Area.

Mount Hamilton Road climbs out of San Jose to Lick Observatory, Del Puerto Canyon runs west from Patterson, and the Central Coast routes wind through Carmel Valley and the back roads of Paso Robles wine country.

58 routes in California cover 1,991 miles and 22,720 graded corners — 5,061 of them tight enough to grade a 1 or 2. Most of them start around Carmel Valley, Paso Robles, Palmdale and Crestline. The twistiest, King Ranch Road + Extras, packs 23.6 corners into every mile for 8.4 mi.
