Answer: The correct answer is: Diving.
Daily rates for certified cave divers are $22, and $30 for all other divers.
If you’re not interested in scuba diving, but simply want to take in the natural beauty of Ginnie Springs, it will still cost you. General admission is $12 per adult ($3 for kids between the ages of 7 and 14; kids under 6 get in for free), and camping overnight runs $20.40 per adult ($6 for kids between the ages of 7 and 14; kids under 6 stay for free).
