This site below will help you decide! Or not, there are frankly too many choices. Personally, I adore Ticino. We spent 8 days in a lake front fewo in Locarno last October, the train/bus/boat options to get to trails made it super easy to go somewhere different every day; we bought a local version of the Swiss Pass and used it multiple times a day. However, we're not into "challenging" walks, so your mileage may vary. I really don't think you can go wrong anywhere in Switzerland, sunshine is easy to travel to from many locales, depending on the time of year. Have a wonderful time!
