4 Adults are starting to plan a trip late August into 1st week of Sept. The only thing we have is reservations at Crater Lake for 2 days Sept 2nd and 3rd, flying in from South Carolina and trying to see the coast and red wood forest, plus Crater Lake. Should we start from San Fran, Eugene,or Portland?? Can we squeeze in Napa? We have 8 days. Trying to decide where to start.
