☠️ Cueva de la Muerte – the deadly mercury tunnel Tucked away in the hillside is this former tunnel, once used to extract mercury, now known as the "Cave of Death." Poisonous gas (including mercury vapor) constantly escapes from within, making the cave extremely dangerous. A fascinating, yet threatening, site of geological and historical significance. Tip: Never enter! Even a few breaths in the tunnel can be life-threatening. Observe only from a safe distance and treat the area with respect.

This hut and the tunnel can be found when you cycle down the hiking trail from PVH Hütte Eulenbis towards Erzenhausen. Be careful, there are some steep slopes where you have to brake a lot. And lots of tracks from forestry and tractors. So be careful when cycling down

The stalactite cave was rediscovered in 1911 after being forgotten. It is a 76 m long tunnel system that was created in the 18th century by mining work. You should definitely take a good flashlight with you when exploring the caves. Waterproof shoes are also recommended as the floor is one huge puddle.

This is where the escaped and dangerous burglar Peter Stein hid in February 1849. And this is where he was caught...

Not so easy to find from above. Over the take-off hill, take the narrow, winding path down! Lovely picnic spot with a view and a lovely story about the Fri-Fra Loch!
