Near Isny im Allgäu there is a very special sight for nature fans: the Eistobel. In a nature reserve of more than 3.5 km, you can marvel at the unique natural spectacle with impressive waterfalls, high rock walls, deep whirlpool holes and imposing boulders. Those who do not want to explore the unique natural spectacle on their own via one of the four circular hiking trails can book one of the many different guided tours and learn more about the geological world of the ice goblet. Numerous plant and animal species, such as the rare dipper, can also be discovered in the nature reserve. Extra tip: Good shoes and surefootedness are a must for the sometimes uneven path!
