To reiterate, Switzerland is an integral part of the Eurail Global Pass network. This inclusion allows travelers to hop on and off the highly efficient Swiss Federal Railways (SBB) and several partner private lines. While the Global Pass covers the "base" travel between cities, Switzerland is unique in that it has many "private" mountain excursions. For these, the Eurail Pass acts as a discount card, often providing 25% off for lines like the Gornergrat Railway in Zermatt or the Pilatus Railway. It is also important to note that the Eurail Pass covers several lake boats in Switzerland, such as those on Lake Thun and Lake Brienz, which are operated by BLS. If you are a resident of Europe or the UK, you would use the Interrail Pass, which offers the exact same coverage in Switzerland as the Eurail Pass does for non-European residents. For those focusing exclusively on Switzerland, the "Swiss Travel Pass" might be a better value as it includes local buses, trams, and free entry to over 500 museums, which Eurail does not.
