We travelled from Zurich to St Moritz and Lucerne via some of the most scenic train rides in the world, including the Bernina Express, the Glacier Express and the cog railway up Mount Rigi.
En route, we visited world class museums, rode an electric bike, crossed Lake Lucerne by paddleboat, and recuperated in one of Switzerland's best mountain spas.
