the coast road from la to San Fran is the best drive I've ever done
Do it over a couple of days... Good place for a stop over is Big Sur about halfway down...
My tip for your roadtrip if around the Grand Canyon area is to nip up into south western Utah for Monument Valley and Bryce Canyon... Both pretty surreal places!
Bryce Canyon - Try and get to one of the viewing points for sunrise if you can, absolutely stunning.
Thanks for all the help guys. Im certainly going to have a look into and see what comes up. Is there a age limit for hiring cars over there. Im only 20 so i think i might struggle?
