Please help... We (2adults) are coming to California for a well deserved break over the Xmas break and beyond. We love the outdoors and have travelled extensively but not in the USA. Really want to see national parks, not cities so much. Will have a car, 4wd an option if needed and want to see desert areas as well as beaches. Can fly into Lax or SFO and don't have to leave from same airport as we arrived in. We want to see Vegas and SF but dont mind missing La or San Diego. Should we see Tuscon or just stick to the national parks? Pretty flexible really but do want to try and see the non commercial side of this area, not what we see on TV.
What are the not to be missed areas for our road trip?
