Hello, I will be visiting for 10 days and looking where to buy the half fare card. I’ve found the SBB site, and another called Swiss-pass.ch. Should I stick with SBB or are there any other sites I could purchase from? Not sure if prices may vary or not.

Was planning to go to the falls but it seems the pkwy into it is closed, are there any alternate routes to get there?
