An overview of the crime mystery trails
Murder in the Moor
On the Voralpen-Express
In 2001, the young monk Father Markus disappears from one day to the next without a trace. The police are in the dark and the case is shelved. Now, over twenty years later, a gruesome discovery is made in the Rothenthurm upland moor - the case is reopened...
Murder in the Castle
On the Alpenrhein Express
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 idyllic stretch of countryside between Lake Walen and Lake Zurich is thrown into turmoil when two bodies are found in the water—at first glance, seemingly unrelated. But it soon becomes clear: both victims were known in the area. And they were anything but popular. Two lakes, a quiet canal, and plenty of gossip from sharp-tongued locals form the backdrop for this mystery trail, which takes participants from the romantic shores of Unterterzen, past the historic Linth Canal, all the way to the cozy town of Schmerikon.
