Astoria, Leavenworth, hit cape disappointment when you're in Astoria. If you wanna hit Eastern Washington, look for falls, there's several depending on how far east or whatever you want to go. Have heard great things about the 'ape caves' but haven't been myself. The drive from Yakima along highway 12 is great, but can be a litte dangerous depending on how snow goes next month ... but based on Oct. that is likely not a problem. There's skiiing at the top, but not necessary.
