Rail pass help

Welcome to the forum c1628. The Swiss Half Fare Card looks like a good option. Specifics and purchase options can be found at the Swiss Half Fare Card page. You don't need seat reservations for most trains and it's best to buy each discounted ticket just before you board the train or bus.

The Golden Pass Line is the most scenic route to Montreux indeed. It's best to make seat reservations online in advance. You don't have to buy your discounted tickets yet; you can do so before boarding the train, as long as you've arranged for your reservations. Make sure that you buy a ticket via Zweisimmen and Gstaad (otherwise you may end up with a ticket that covers another, more direct route).

Hello c1628! You can board the Golden Pass in Interlaken or Spiez. Connections can be found in the regular timetable and at the Golden Pass website. If you make sure you arrive in the late afternoon or early evening, there will still be enough light along the route. Your Swiss Half Fare Card is valid indeed (apart from the additional seat reservation fee).

Hi again! I just saw that you posted pretty much the same questions in a new topic. Creating a new topic for new questions is fine, but in order to prevent duplicate questions (from the same forum visitor) I'll remove that one. This is also mentioned in our forum rules.
