Hi Nomad44, welcome to MySwissAlps!
If you'll be focusing on the Bernese Oberland, a Regional-Pass Bernese Oberland may be a very good deal as it offers free traveling throughout the region. This even includes quite some mountain trips. Please find details, including a validity overview and purchase options, at our Regional-Pass Bernese Oberland page. Does this seem to fit your plans?
If you want to make sure which pass is best, you should make calculations as explained at our "How to choose" page.
