Jackson Blue is one of the cave systems feeding the Merritt Mill Pond near Marianna, FL. It has a beautiful cavern zone, and the cave system is one of the prettiest I’ve ever seen, with clean white limestone.
It is normally a fairly high flow system, which limits penetration unless you’re using a scooter.
It is located in a county maintained park, and requires paying a $20 fee to get into the park. Contact Edd at Cave Adventurers to buy your permit.
PLEASE NOTE: This is a CAVE dive - don’t attempt without proper training and equipment.
