This was the craziest spot in the area.

How to get here: First you have to reach the spot from which you get the first view of Tre Cime's iconic side. There is a crossroad. Instead of continuing forward turn your back to Tre Cime and walk towards the huge mountain. There is only one path leading up. After 10 minutes you will reach the first tunnel.

We're not sure how far this path goes since we turned around after few minutes. It seems a bit dangerous and there are some exposed parts where you have to hold on to the rocks and use a rope. You can certainly take your kids here and once you get to the point where you start to feel uncomfortable.
