Pacific Coast Highway (PCH) is a portion of State Route 1 (SR 1) running along most of the Pacific coastline of the U.S. state of California. It is also part of the larger Pacific Coastal Highway that extends along the Pacific coast of the entire Americas.
This asphalted state highway runs along some of the most beautiful coastlines in the world, leading to its designation as an All-American Road. It’s heralded as one of the most scenic drives in USA.
The road's winding design, providing stunning panoramic views, is very curvy and fun for a leisurely ride, so it pays to take it slow. Drive north to south if you're able to choose. That way you're on the coast side of the highway, which means better views, and it's much easier to pull off into the best viewpoints. Allow plenty of time. There are lots of viewpoints, official and unofficial. The Pacific Coast Highway is a state of mind. It’s one of the most beautiful road trip drives in the United States, so do as much of it as you can in the time you've got available. There are some great beaches and seaside towns that require you to get off the highway and explore them. Likewise there are some state parks and gorgeous areas.
The surface of the road is asphalted. Don't run out of gas. They tend to get less frequent the further north you go. Even in one of the most famous and most beautiful stretches of the road, Big Sur, gas stations are pretty spread out. Don't take chances.
