Falkenstein Cave - Falkensteiner Höhle
Summer months and dry weather are the best conditions to get about 150 meters deep inside the cave. Of course, you can get deeper into the cave, but it's highly recommended to do with a guide. Check the weather forecast first, if severe weather is predicted don't enter the cave. At the end of July 2019 two men; a guide and his client got trapped in the cave. The water level became too high for leaving. A rescue team of 90 people got them out alive. So please, the Falkenstein Cave is not accessible during winter, when heavy rainfall is predicted and, after rains. None of these caves shouldn't be entered from October to mid-April. Usually, caves are home for protected bats in the colder season.
The Falkenstein Cave is located in the Swabian Alps, close to Bad Urach and south of Grabenstetten. From the car park, it is a short walk to the entrance. It is an active cave that means a river is flowing through. The source of the Elsach river is rising in this cave and disappearing into a sink hole. In summer it is possible to walk inside of the cave almost dry for 150 meters with rubber boots and neoprene socks, minimum two flashlights. Hereafter the water level is chest deep for the first time, and the temperature is around 7 degrees. After rainfall and in winter the water level is too high for the sink hole, and the river is flowing out of the cave. If the river flow is too strong and high even the trail get flooded sometimes damaged. The cave is several kilometers long and only for experienced cavers accessible. Guided tours are offered from mid-April until late September depending on water level inside of the cave. Early booking is advisable. We tried to book it just a week before, but unfortunately, it was already fully booked.
