Hi kosara2,
The link under "More on other websites" on myswissalps.com/car/tr afficinfo provides details. Click "Pässe in der Schweiz". Unfortunately it's only in German but you can have it translated by your browser if you don't read German. It's a bit hard to provide a suggestion as I don't know how long and where you will stay. In any case May is not the best season for road trips as all the higher passes could be closed, although that's not sure, so you'd best plan when you're there and conditions are known. The page I gave you shows current road conditions. Nearly all passes are interesting scenery wise, but the lower ones which are always open (e.g. the Brünigpass) are very different from the higher ones. The Klausenpass should also open somewhere in May. You can also opt for a scenic train ride. They operate all year round.
Do you know how to drive in the mountains? If not, be sure to read this.
