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!

The steep path to the quarry has been washed out and is very rocky due to the heavy rain in recent months. Each biker has to decide for themselves whether the stairs at the end of the trail are rideable.
