We will be flying into Geneva, staying in Lauterbrunnen for 8 nights and plan to do a lot of hiking and exploring the area - assume a lot of high mountain lifts on a daily basis. It seems that the Swiss pass provides a 50% discount on most mountain rails and cables, but I'm wondering if it would be a good investment to get one of the regional passes. it's difficult to find prices for the mountain transport, which makes it hard to do the math. We're also planning day trips to Lucerne and spending a couple of nights in Zermatt.
Any advice would be much appreciated.
