Gilfklamm

Following the  Passer river in the upstream direction you reach the Gilf gorge, a narrow valley with a terrain jump towards the Passeiertal. Sandwiched between rocks, the river must pass through narrow walls of rock to reach the city.
The swirling moisture allows many plants to grow, which is why the Gilf is also botanically interesting. From there you can reach the Tappeinerweg.
