What will be the cheapest package if I want to travel every weekend between Geneva and Lausanne only for 2 months

Walking or biking won't cost you anything.

Hi!

I recently discovered that sbb sales supersaver tickets:

You can order it in advance and enjoy some nice discounts. I never ordered it but I plan to do it in the future for a trip to Geneva. Have a nice day.
