Honestly if you like wine you are guaranteed a good trip. The competition is so fierce that bad places are gone in an instant. There is some hiking and activities on the river like SUPs. Things were insanely expensive when I was there a few years ago. I think we looked into a hot air balloon package and it was like $2,000 for a two hour trip for two people (breakfast afterwards was another $50). Having never taken a balloon trip that may be reasonable, but it seemed crazy to me.
