An overview of the crime mystery trails

Murder in the Moor

On the Voralpen-Express

At first glance, Einsiedeln and the area around the Rothenthurm Moor seem to be the perfect idyll. But appearances can be deceiving – a murder has been baffling the police for decades...

Murder in the Castle

On the Alpenrhein Express – New from June 2026

The theft of a worthless painting casts suspicion on six people, as the thief is found shot dead shortly afterwards. Three stately castles, a national border and a perfidious murder form the backdrop to this crime trail, which takes you from Sargans through the Principality of Liechtenstein to idyllic Werdenberg.

Murder in the Canal

With the IR Aare Linth – Bookable from autumn 2026

The case is still in its early stages. Clues are scarce and suspects are yet to be identified – but the story is already taking shape. We’ll be revealing more about this new crime game very soon.
