The Pacific Coast Highway is also known as Highway 1. It runs along the pacific coast of California. You can start up north in San Francisco and drive down to Los Angeles. There are faster alternatives like the Interstate 5 and Highway 101 which runs further inland. I have done the pacific coast highway four times in a year and I still want to do it again. You need to add this scenic drive to your to-do road trip list and I mean it. Flipping through any travel guide books or Google searches will reveal that it is often mentioned in them. It is usually in the top ten road trips in the world and it really does live it up.
