I recently spent 9 days in Eastern Washington, visiting some mountain ranges well beyond the familiar realm of the Cascades.  I visited 30 mountaintops including many which still have lookout towers atop them, like Moses Mountain (pictured).  The weather was terrific for the most part, and I became very familiar with an entire region of the state which had been unknown to me previously.  I have to say that there aren't really an abundance of great hikes over there, but definitely a few that are very nice.  It's really just hilly country, lots of forests, and scattered small towns.  Still, places like Mt. Bonaparte, Abercrombie Mountain, Moses Mountain, Mount Rogers, Molybdenite Mountain, Sullivan Lake and Mount Spokane were memorable.
