ISO camping that involves a bit of backpacking... <5 hours drive from Portland?

Looking for something that is less than 5 hours of a drive from Portland that could provide a couple of miles to hike into a camping spot. Camp for 2 days... would be awesome to drive in late Friday night. And then spend Saturday hiking into the campsite. Sleep there, spend Sunday hiking out in the morning head back to Portland. Any suggestions are greatly appreciated.
