Does it cost anything or is there anything I must do if I want to take family pictures at the scenery and trails?

It is free to walk about the property. The only thing that has a fee is the cave itself. There are several nice, well marked trails and a observation tower that is a must see. Enjoy!

Cavern entry has fees, once inside, no flash on camera's rule is enforced.

No cost to walk trails or see park area. Only pay for cavern tours.
