Bodega bay to rockport could be a trip in its own. lots of small towns and food and hikes etc. shelter cove on the lost coast is neat but i usually only go there if im flying my own plane becuase the drive in is kinda long. all the parks around redwoods are nice. trinity alps in the shasta area have better hiking imo. some great fishing. lower/upper sac. mccloud river, klamath, trinity, eel, pit, hat, rogue, umpqua, the list goes on. Southern oregon coast is incredible. stops with short hikes every quarter mile or so for the entire length. could also do a house boat for a day or two on shasta lake or trinity lake. lots of activites on shasta lake also for day trip. Nice wineries in grants pass, roseburg and corvalis. not exactly southern oregon but silver falls state park is sweet. as is the bend area such as smith rock. personally not a huge fan of crater lake. Big area with a million things to do in any given part of it. As you refine your itinerary, follow back up and I can likely provide more detailed recommendations for food/activities etc if needed
