First, you walk through a low tunnel far into the mountain, where you are finally given a detailed explanation of the working conditions in former times and what happened in the tunnel during the Second World War, including the construction of the first fighter jet. After the mine tour, you continue a bit further down to the largest underground lake in Europe, where you take a short boat trip. The lake is very clear, the air is great, and the lighting is also very beautiful to look at. We went to the Seegrotte purely by chance and were lucky enough to get a private tour, as apparently no one else wanted to visit the grotto at lunchtime. Our guide was very nice, explained everything in great detail, and in the end, we were even allowed to do two laps on the lake.

The Einöd Cave is well-known as a significant habitat for bats, particularly the Lesser Horseshoe Bat.

Natural outdoor formations or trails leading to caves might be dog-friendly, but access to actual cave interiors, especially those with sensitive ecosystems like bat habitats (e.g., Einöd Cave), or commercial attractions like Seegrotte Hinterbrühl, often have restrictions. It's best to check with the specific cave's management beforehand.
Parking availability varies by location. For popular sites like Seegrotte Hinterbrühl, dedicated parking facilities are usually available.
