I'm planning a two week trip in mid July, starting in San Fran and ending in Vancouver. I'd like to spend a few days in both cities, as well as a couple of days in both Portland and Seattle. I'd really appreciate any suggestions as to what else to visit within the timescale we have. Would love see some of the coastline (ideally warm beach, and also redwood forest). We were thinking of driving from San Fran to Portland, then taking trains from Portland to Seattle, and Seatte to Vancouver. Is this realistic/advisable?
Any thoughts, suggestions etc would be very welcome.
