We will be going to Ore. at end of July for 7 days. We've driven the coast on a previous trip, so we'd like to spend apprx 3 days in Portland and then stay 3 days in another location, just to break things up. We were considering the wine country, even though it is close in. We like to hike and bike, but we won't have our own bikes. is it necessary to end the trip in Portland, since we will be flying out from there? All itinerary suggestions are welcome!
