Wayanad is a must visit. You can cover some places in Karnataka and some in Kerela that are nearby. This way you'll get best of both worlds. Maybe Coorg, Bandipur in Karnataka and then come towards Wayanad in Kerela and Kunnur.
Karnataka has a lot of beautifull places but i prefer kerala because it has a different kind of beauty. Kerala also known as the "God's own country" for a reason
