I'm currently in the process of planning a Summer/Autumn holiday from Ireland to California. My initial plan was to drive up the West coast from San Diego to San Francisco and possibly into Napa Valley or in the opposite direction. After doing a little more research a few other areas of the interest have come to my attention i.e Redwood National Park, Death Valley, Las Vegas, The Grand Canyon, Lake Tahoe, Yosmite.
I have two (possibly three) weeks, I was wonderin are all of these places possible to visit in this time and what the best possible route to take would be? Also if I had to prioritise which sights would be the best to see, any information would be great.
