Bodenloses Loch

The Bodenloses Loch is a karst spring in Diebach with an opening measuring approximately 15 meters wide and 20 meters long. Water emerges from a depth of about 6 meters and displays a characteristic blue coloration.

The spring formed through natural dissolution of underground gypsum layers deposited during the Triassic period approximately 230 million years ago. This geological process continues to shape the landscape today.

Local folklore suggests the spring extends to America, with tales of submerged castles and mermaids dwelling in its waters.

The site is located near the Wörnitz exit on the A7 highway and is best reached on foot from the Unteroestheim district. A short walking path leads through the countryside to the spring.

The spring releases between 60 and 80 liters of water per second while dissolving 4000 to 6000 tons of gypsum annually. This enormous volume demonstrates the powerful underground process at work.
