At 655 miles long, Pacific Coast Highway is the longest state highway in California and it passes right through Orange County's stunning coastline from the junction of Interstate 5 in Dana Point to Sunset Beach. Along this 35 mile stretch, you will encounter 3 harbors (Dana Point, Newport, and Huntington), several shopping districts, many restaurants, piers, clear blue coves, sandy beaches, a state park, wildlife estuaries, and great surf breaks. Whether you live here or you're from out of town, PCH is always a beautiful drive.
