We recently went on a trip down through the center of Oregon past Crater Lake to Rogue River. That is an incredible drive. The scenery is awesome. On the return trip we did the crater lake 7 mile loop.
If you like to take photos, that is the drive. The people in that area are very friendly also. I was lazy and only took the tent this time. The neighbor in an RV next door came out and offered me coffee and asked if we needed anything else.
