I'd recommend overnighting at one of the three campgrounds on the east shore of
Waldo Lake if you can swing it. It's a beautiful area and only about 10 miles off of Hwy. 58 and 35 miles outside of Oakridge.
We spend a week up there every August, and will be there the week of the 15th this year. The scenery is amazing, it's totally quiet (thanks to no motors allowed on the lake and being well away from Hwy 58 traffic and train noise), and there's a lot of hiking, kayaking, and mountain biking available. We usually stay at the Shadow Bay campground, as it has some more tree cover and is generally cooler, but the two north campgrounds are nice, too.
