Gustav Jakob Cave - Gustl
The cave is closed from October until the end of March to protect the bats. It is advisable to visit the cave with dry weather conditions.
The cave is open from April to the end of September.
The Gustav Jakob Cave nickname Gustl was discovered in 1936 by Gustav Fetzer and Jakob Kazmaier. The cave is more than 400 meters long and the longest dry cave in the Swabian Alps. It is a steep descent along a small trail through the forest to the entrance of the cave. It is not dangerous to enter the cave. It takes about half an hour with several stops to enjoy and to have a look around.
Very important there is one entrance and one exit to avoid to burst upon other cavers! It is often too narrow to let people pass that means one group has to move backward. In the beginning, you can stay inside later on depending on your size you need to crawl. After 200 meters you reach a hall where the whole group can stay together. The cave is often very tight, narrow and winding. For smaller people like me, it was very easy for my husband more difficult. In the end, even I had to crawl. The car park is not far away. Don't take a backpack with you; it makes the adventure even more challenging. When you get out of the cave, you walk back uphill and climb up a ladder. At google maps, I marked the car park for the cave. Above the cave on the top of the hill is the ruin Hofen. Enjoy the view from here.
To find the entrance to the cave we used Locus Map on our mobile. Very important have a headlight and flashlight just in case. You walk in complete darkness. Unfortunately, we met a group inside of the cave; they took the wrong entrance. They had worn helmets. To be honest, we didn't because you might hit your head even more often.
Take your time, enjoy and be careful.
