One of our most memorable trips included Lauterbrunnen. The valley, waterfalls and the peaks are amazing, I can still hear the cow bells in the fields. Not sure if you would drive or train?, quick google shows just over an hour by car and over 2 by train. basically you would get to Interlaken, then up the valley to Lauterbrunnen. From there I'd continue up via mountain train to Grimmelwald, Murren and a gondola all the way to the Schilthorn Piz Gloria!
