I live in the area and highly recommend going from Three Creeks Lake to Waldo lake. It is a great excursion. The three creeks trail might have some burn residue from the recent Mili fire but I think it is mostly under control now.
Here is the route post I used to navigate the roads. All are very well marked.

There is also some great trails and sites like Fort Rock and Newberry Crater.
