Arriving to Zurich in two weeks, myself, wife and children 18yo and 19yo. Trying to figure out best combination of passes that would be useful and cost saving. Zurich to lauterbrunnen which will be home base for a week and anticipate regional travel to Interlaken, lake Brienz, murren , grindewald, Klein schediegg, gimmewald, etc and other local villages and then back to Zurich a week later. Plan on mostly hiking and pursuing outdoor activities/adventures so plan on several trips per day. Thanks!
