Ice bathing in summer? Sounds impossible, but it's possible in Tyrol's largest glacier cave. We don't even know why almost nobody brings their swimming gear when they visit here... but a boat trip across the underground glacial lake is fun after all. And you can marvel at the many ice wonders of the glacier cave much better in warm clothing anyway.
Admittedly, the almost vertical Martinswand does not look particularly accessible. And yet the cave, which can be seen from afar, can also be reached by families via a well-secured path. Emperor Max didn't have it so easy back then.
Marble, mill, running water. Sounds like a classy kitchen facility for DIY enthusiasts? That's right. But that's also the name of three of the cave points on the Hintertux Glacier. But don't be misled: there is of course nothing to eat on the three tours through the interior of the mountain.
If you want to find Stone Age relics or bear bones in this cave, you can save yourself the trip, as they are already on display in the valley. But then you would miss out on a rather adventurous hike and this place of power, and we really don't recommend that.
Hiking, Kaiserschmarrn, pedal boating at 2,300 metres above sea level and then exploring Tyrol's second-longest ice cave... sounds a bit much for one day? Anyway, pack your toothbrush and sleeping bag and stay in the Obstansersee hut, then you'll finally be able to jump into the mountain lake in the morning.
