My husband and I are traveling to Portland for an anniversary trip. We are wanting some time in the city, as well as some hiking/scenic sightseeing. We are planning to stay 2-3 nights in Portland and 1-2 nights somewhere else. We are trying to decide between spending the night in Hood River or Cannon Beach/Astoria. Can we do Columbia River Gorge as a day trip from Portland or would we enjoy it more if we spent 1-2 nights in Hood River. If we can do a day trip to the gorge, we could then drive to the coast and spend a night or two there. Is this too much to pack into 4 nights? We will be there the end of Sept.
