California's SR 1, also called the Pacific Coast Highway, is one of the most scenic drives in the nation. Stunning ocean vistas all but define this coastal route. Don't drive SR 1 if you're in a hurry (that's what I-5 is for). Most of this nearly 656-mile-long roadway is two lanes, narrow and winding, which means you'll want to slow down and admire the many gorgeous views.
