Have traveled north to south on CA 1 from where it diverts from 101 at Leggett down to Petaluma. It is a wonderful drive with Bodega Bay, Fort Ross, Mendocino, and Ft. Bragg. I would travel south again from Leggett with our 29 ft. Trek motorhome, but I would not recommend doing it from the south after Ft. Bragg. Leggett to Westport involves 10 mph turns and you would be going uphill. Head inland from Ft. Bragg on hwy 20.
Relax, be safe, drive defensively and you will have a great time and see some beautiful sights.
