There is an entrance fee per person based on age and or height. If you're a Collier County resident you get a discount. You need to bring towels if you wanna dry and there is food at cost. They don't allow coolers and outside food/drinks. They do provide life vests free of charge. I would visit the website or call during business hours if you have further inquiries.
There are also family passes available. As Ron stated, it is all laid out on the website.
