THROAT (SIGMUND-THUN KLAMM)

One of the natural passages of the very picturesque valley. 14,000 years ago, the site was occupied by a glacier. Over the centuries, the glacier melted and the water runoff carved out this 320 m long and 32 m deep gorge through the rock. You walk through this gorge on a wooden grating overhanging the river and its waterfalls to the cave. Bring waterproof clothing. At the entrance, visit the museum on local geology. Perfect for families.
