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!

Unfortunately, the cave was completely overrun with visitors when I visited. Therefore, I recommend not visiting this place on the weekend, unless you want to enjoy the deliciously fragrant grilled food that is offered right next to the cave. The cave is surrounded by many legends and stories about meerkats and meerkat women. A visit is definitely worth it, whether to enjoy a delicious lunch or to take in the mystical surroundings.

At the Ramsflue above the sleepy hamlet of Hard, there is a small cave between high limestone towers. A beautifully laid out forest walkway leads past it. According to legend, dwarves used to hide there. Anyone who dares can enter the cave. Happy, colorful little fellows and dangerous tigers await the visitor ;-)
