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 Grotto of Mary is located on a forest clearing below ground level, the entrance is secured with posts or a small concrete wall, the interior of the grotto is largely natural. At the entrance there is a small table and a seat, a small bell can be rung by pulling a cord. On the right side of the grotto is a painted statue of the Virgin Mary, modeled after Gothic madonnas, protected above the entrance by a wooden gable roof, a carved, unframed figure of the Virgin Mary in the style of the mantle madonnas.

Where Mary is venerated and prayed to, faith takes root and becomes alive and strong. Where Mary is loved, the Church is also loved.

Höllensteinlucke – the breather for altitude heroes 😅 Are you on your way to the Höllensteinhaus, panting like a broken vacuum cleaner and wondering if you're lost? Don't worry – you've arrived at the Höllensteinlucke! 🎉 This legendary "lucke" isn't a magical portal, but simply a small cut in the terrain – but for tired hiking legs, it feels like a gift from the Vienna Woods. 🌲✨ Here you can take a short breather, question your existence, and mentally prepare for the final climb. Because from here on, things get tough again – but hey, you're not here for fun. Or are you? 😄
