After finding a hole in the forest floor a group of spelunker's decided to explore its depth and to their amazement, it lead them into a massive cave. This is what a spelunkers Christmas looks like.

Spelunking, which is often referred to as "caving" isn't for everyone. Even just watching these videos makes the hair on my arms stand at attention. Watching as they squeeze through rocks and cracks makes my chest tight. I couldn't imagine doing it, not if my life depended on it.

Which is why YouTube is such an amazing gift to the world. Are you a big baby? Maybe you're just lazy? Well, no matter your excuse, you can get all the wonder and second-hand anxiety that comes along with exploring caves without even putting on your shoes. So sit back and try to relax, because things are about to get a bit claustrophobic.
