My wife and I are trying to plan a vacation to see the redwoods. She also wants to drive into Oregon to see crater lake. We where thinking of flying into SF and driving up to Crater Lake for a day. Then driving across to Creasent City for the redwoods. Then driving down the coastal hwy and back to SF to fly home. Is this a doable trip and is there anything that we must see along the way. Thanks in advance for any input.
