The cave's two indentations form a kind of pair of glasses, hence the name. It is an important archaeological site. Therefore - and for safety reasons - the interior of the cave cannot be entered. It is always an impressive sight.

You can find everything from large cave systems and show caves to natural grottoes and even a unique vertical cave. This geological setting offers insights into natural history and geological processes.
Yes, the Swabian Alb is rich in historical caves. The Hohle Fels Cave is a UNESCO World Heritage Site, famous for being the discovery site of the 'Venus vom Hohle Fels' and the 'Vulture Flute', both among the oldest known artworks and musical instruments in the world. Additionally, the Sontheimer Höhle holds the distinction of being Germany's oldest show cave, with visits recorded as early as 1516.
Several caves around Allmendingen are family-friendly. The Sontheim Cave offers guided tours through its dripstone formations, and it has a guesthouse and playground nearby. The Blautopf, while primarily a lake, features a large, mostly underwater cave system and is a popular, accessible natural spectacle. The Laichinger Tiefenhöhle is also equipped with carved steps and metal ladders, making it safely accessible for visitors of various ages.
The caves maintain a consistent cool temperature, typically between 6°C and 9°C, making them a refreshing escape during hot summer days. They can be visited year-round, but it's always advisable to check the specific opening hours and seasonal availability for each cave, especially during winter months.
The caves showcase impressive geological features. The Blautopf is a karst spring known for its striking deep blue color, caused by light scattering on tiny lime particles. The Laichinger Tiefenhöhle is Germany's only publicly accessible vertical cave, offering a rare opportunity to explore a significant vertical system with stunning dripstone formations and evidence of ancient cave streams. The Sontheim Cave also features fascinating dripstone formations.
The Laichinger Tiefenhöhle provides a truly unique experience as Germany's only publicly accessible vertical cave. Visitors descend approximately 55 meters into the earth, traversing 330 meters of passages through massive shafts and large halls. It offers a distinct perspective compared to more common horizontal caves.
Some caves offer amenities on-site or nearby. The Sontheim Cave has an attached guesthouse (Rasthaus) where visitors can enjoy refreshments. The Laichinger Tiefenhöhle features a speleological museum at its entrance building, which can be visited independently of a cave tour.
The region offers various outdoor activities. You can find numerous routes for mountain hikes, such as the Blautopf Spring – Blautopf loop from Blaubeuren. For cyclists, there are options for gravel biking and cycling, including routes like 'The first kilometers along the Aach – Hohle Fels Cave loop from Großallmendingen'.
Given the consistent cool temperatures inside the caves (6°C to 9°C), it is advisable to wear warm clothing, even on a hot day. Comfortable, sturdy shoes with good grip are also recommended, especially for caves with uneven terrain or steps like the Laichinger Tiefenhöhle.
The Trail to Brillenhöhle leads to a cave that has been noted as being closed for renovation work. It's always a good idea to check the latest information for specific caves before planning your visit.
The duration of a cave visit varies. For show caves like the Sontheim Cave, guided tours typically last around an hour. Exploring the Laichinger Tiefenhöhle, with its self-guided audio stations, might take a similar amount of time, depending on your pace. Shorter grottoes like the Little Grotto can be explored in less time.
