Planning a road trip in April, flying in/out of San Francisco and thinking of staying 10 days but possibly up to 14 depending on how much we want to fit in. Only planned stops so far are 2 days in San Francisco at the start to recover from the flight from the UK.
We want to see as much spectacular scenery as possible in the remaining time, also with time for outdoor activities and some relaxation, but not sure how much we can fit in. Is some sort of round trip possible - starting southwards on the coast and returning north via Grand Canyon, Death Valley, Yosemite and Lake Tahoe? Trying to strike a balance between seeing as much as possible and not needing another holiday when we return!
