I've driven most of the paved part and it is a nice country road. There are a lot of homes and farms for the part I've seen. Views are nice but not spectacular. Never stopped to take photos since we were usually heading up to Black Pine Lake to go fishing. There are two roads that go there off of the Twisp River Road and both are paved and uphill if you wanted some climbing but they are rough and turn to dirt after a few miles.
Found some fall photos someone posted that shows the Twisp River road.

I've thought about riding it but I always find something else I'd rather ride when over there. There are a couple of side roads off the Chewuch that I haven't done and I'll repeat the ride to passes every time I'm there.
You've probably done all the scenic rides there that are paved. Sun Mountain is short but nice. We rented mountain bikes when we were over there in early June and that opens up a lot of scenic rides in the area.
