My sister and I will be arriving in Portland late Aug.3. Our plan is to drive from the airport straight to Hood River where we already have hotel reservations. We plan to spend Aug 4 making our way back to Portland by exploring the Colombia River Gorge area. My question is knowing we would like to be back in Portland by dinner time what should be plan to see between Hood River and Portland to get the best time out of our day in the area. Thanks in advance!
