It is currently for sale here for .99 and it includes a scavenger hunt you can do on your drive that will get you a poster I created highlighting my favorite stops. I have either stayed at all of these myself or they have been recommended to me by people I trust.
Update May 2017: A few parts of Big Sur are closed due to damage from landslides and weather.
Be sure to check on the conditions before driving through the area as it is possible that it will not reopen in 2017.
The Big Sur segment was initially the Carmel–San Simeon Highway or Route 56.
The Highway 1 designation first appeared locally in 1939.
In May of 2016 I completed an e Book guide for Pacific Coast Highway.
This e Book takes my recommendations, adds more details and packages it into a format (PDF) that you can take with you on your favorite device and use offline.
Although popular for its scenic beauty, the Big Sur segment can be hazardous.
Landslides and erosion have caused several closures for repairs.
The highway might not exist today had a single determined Malibu landowner prevailed in her long struggle to enjoin Los Angeles County from starting it.
Since at least the 1890s, a primitive carriage road had run the rocky coast north from Santa Monica only to end at a barrier at her property line.
If you have to go around, consider going to Pinnacles National Park which is an interesting stop. Santa Cruz has a lot of great spots and great food places, but Natural Bridges State Park is one of my favorites by far.
