Christine Falls was such an easy but pretty stop in the park. We actually drove right over the little stone bridge before realizing the waterfall was there and pulled over to explore (there is a pull-off directly after you cross the bridge). Once you get out of the car, there are a few different spots you can wander to for views of the falls and bridge. We visited in the fall, so all of the trees around us were shades of orange and gold, which made everything feel extra moody and very Washington. It only took us a little while to explore, but it was a great side quest!
