Deep Cave in Edwards County, Texas has more than one entrance, but daredevils prefer to use one so tight that it can make claustrophobes extremely uncomfortable just looking at it.
Videos of spelunkers literally squeezing themselves into Deep Cave through this incredibly tight hole in the ground have been doing the rounds online for years now, but frankly, they never get old. It’s terrifying, it’s electrifying, it’s something you don’t really want to see, but can’t really stop either. Even if you don’t really have a problem with tight spaces, seeing people going down this little hole is guaranteed to make your palms a little sweaty.
