Quite stable suspension bridge, but especially the access path from Hohtenn is only suitable for sure-footed and vertigo-free people

The unlit and very dark tunnel has a handrail in places. This allows you to move around the tunnel relatively safely. If you still feel unsafe, you should take a flashlight with you.
