17.50 per person, but you can walk the park and go up in a very old stone tower for free. Well worth the entrance fee.
The state park itself is free. They have picnic tables and 1 display about the caves. However to actually go into the caves, you must take the walking tour (with a guide) which is $17.50 pp. They also offer another cave exploring tour.
16 dollars for each adult.
$17.50 person unless you have TPWD State Park pass. 10% discount.
