Vertical caving can be an awesome adventure and may be attempted by novice cavers as long as they come properly prepared with a guide and adequate gear. A great place for spelunkers with a bit of experience is Petty John Cave of Georgia. As the third largest cave in the state, this natural wonder offers well-traveled routes and a different brand of adventure. Cave formations that you'll see along the way are stalactites and stalagmites, soda straws, cave bacon and cave popcorn.

One of the challenging attractions of this cave is a 150-foot crawl, called the Worm Tube, that is guarenteed to constrict and contort your body. So check your claustrophobia at the door. You'll have to brave this feat if you wanna get to the Echo room, the largest room in the cave, the Volcano room, and beyond. Be prepared for other cave surprises including an underwater stream and waterfall.
Note: This cave is considered a wild cave. As such, a helmet, gloves, sturdy boots, headlamp (and back-up sources of light), knee and elbow pads, and the appropriate clothing are a necessity as many people are injured in this cave every year due to ill-preparedness. Having a basic caving class or two under your belt couldn't hurt either. Minimize your risk by educating yourself and gearing up.
