The route from the bottom is incorrectly navigated; ignore the left turn sign. There's simply a point where there's no way back and the climb is extremely dangerous. There's no solid ground and hardly any way to hold on. We almost called the REGA (Rega Rescue Service).

Getting into the Banana Cave isn't so easy. Crawling is fine, though. After a short crawl, you can soon stand up again inside the cave. It's a unique feeling to be in there.

The Bsnane Cave is a popular tourist destination. Two inconspicuous cave entrances that are connected together, like the two ends of a banana. First you have to crawl to even get into the cave, and then it gets more comfortable in the darkness of the cave, you can even get up and walk to the second cave entrance. And then crawl out again!
