Petty John's Cave is a karst cave located in Walker County, Georgia on the east side Pigeon Mountain in the Appalachian Plateau of Northwest Georgia. It has a surveyed length of 31,490 ft and reaches a depth of 235 ft. The cave is accessible via a path from a gravel parking area on the side of Rocky Lane.

Petty John's Cave is a very popular cave for local students and spelunkers. It is a horizontal cave, but a 50 ft handline is the recommended kit when visiting the cave. Petty John's cave is a wild cave, not a commercial cave, and one should only enter with the proper equipment and training, e.g. three sources of light, water, a helmet, boots, and appropriate clothing. Many would-be explorers are injured here each year. Those interested in exploring this cave and others should contact a local caving club, or grotto. Some of the best grottoes in the country are located very near Petty John's Cave. Grotto members are involved in conservation, cave rescue, and exploration. You can find more information at (the National Speleological Society's website ).
==Passageways==
It starts with an easy climb down into a large breakdown passage. A handline is recommended for the climb down to the stream level. One of the most popular and most challenging of passages in the cave is the Worm Tube. The Worm Tube is a long 150 ft crawl. It is a very tight passageway and unavoidable if venturing to the Echo Room and beyond.〔http://caversandspelunkers.tribe.net/thread/92de9555-dd3d-4b39-aa4e-45fb2cf64159〕 Other intriguing passageways include the Mason-Dixon Passage and the Pancake squeeze. When going to the waterfall or Raccoon Room, the stream canyon passages and the Z bends can be an alternate route to the Pancake Squeeze.
Do not use or trust any ropes or lines left in the cave. Please also help this much abused cave by not damaging formations and packing out trash.
