Alpine Pass Route Overview Map (Cicerone Guide)

… a 340 kilometre (211 miles) hiking trail that spans the breadth of Switzerland. Starting in Sargans on the border with Liechtenstein, it passes up and over sixteen mountain passes before reaching its western terminus at Montreux, situated on Lake Geneva.

I completed the Alpine Pass Route in August, 1997. Nineteen years and many hiking miles later, it remains one of my favourite European trails. A memorable combination of gorgeous mountain scenery, picturesque villages, great hospitality and some very cool side trips …

It’s one of our best hikes in Europe.
