Watch: Roger Federer and Trevor Noah star in Switzerland Tourism ad

During the advert, Federer, the global brand ambassador for ST, takes the Grand Train Tour of Switzerland alongside Noah.

The campaign will be rolled out globally, with a focus on the US, India, Korea, south-east Asia, China, the UK and Germany.

The feature also promotes the Swiss Travel Pass, which is an all-in-one ticket from ST allowing tourists access to the Swiss transport network.

With a single ticket, travellers can explore the country by train, bus and boat over three, four, six, eight or 15 days. 

As part of a special offer, from 15 April to 14 May 2023, up to two additional travel days will be added free of charge when buying the pass.
