The cog railway from Montreux takes us up to four very special attractions at the top: a marmot sanctuary with seven enclosures for marmots from Asia, Europe and North America, the Rambertia botanical garden with more than 800 Alpines from all over the world, the Plein-Roc restaurant hewn into a rock face high above Montreux, plus the chance to spend a night in a yurt.
