You pretty much have to be travelling independently in a rented car to be able to stop at this park. It is right on the highway just south of Cancun.

There are numerous turtles, lizards, crocodiles, monkeys, etc to walk around and see. The guides are really good and speak English.

The entrance fee was quite small, but the guides aren't employed by the park so they live on your tips. A group of 4 of us gave him around $30 for a 2hr tour and he seemed really happy with that.

We got to hold baby crocodiles, and our guide was very amused by us chickening out at one point. He handed us large and larger crocs (starting at about 5 inches long)....when he started getting out the ones that were over a foot we hastily declined.

The other somewhat scary moment was when we went through a small gate and realized belatedly that he had just taken us into the adult crocodile area. Even though its hot and they are torpid and well-fed it takes a little never to stand within a foot or two of these guys.

It is never crowded since it isn't flashy enough to be on any bus tour itineraries.

Visited Spring Break March 2005 with my husband and 14 year old son. Transportation was the collectivo from Playa del Carmen. We had a fun time at this little advertised "zoo." Admission was about $10 or 12. Refreshments were available. You got your own personal guide to take you through the jungle like grounds. English speaking guides were available. We had a nice guy who had limited English but with my limited Spanish and handy dictionary I had fun practicing my Spanish. I got kissed by a macaw, touched various small crocs and snakes, looked at iguanas and venomous snakes, and fed Pepe, the wild pig. and some deer. There was a rather precarious walk through a crocodile habitat with large enough to eat us specimens and only a low rock fence to separate us from them! However, they seemed uninterested. There was a croc hospital. It seems they like to bite each other. The only negative was that there were some monkeys that were tethered to the trees to keep them from escaping and maybe even away from the crocs, but they were very mobile as their tethers didn't keep them from climbing around. We fed them too. They even pointed to themselves to indicate who to throw the snacks to! There was a giant croc at the end and some bored xoloizquintle dogs. Clean bathroom and place to wash your hands after. Great out of the sun activity that even my teenager enjoyed.

Besides the wonderful beaches, friendly people, interesting mayan pyramides, you should not forget to watch the wonderful nature and be aware that nature is somewhat damaged because of tourism. There is a place on the highway from Playa del Carmen to the Airport which is called Crococun.
That place is great to visit, it will take you half a day with good english speaking guides and the entrance is no more than 15 usd. You will meet great part of the local animals like crocodiles, spidermonkeys, deers, mexican naked dogs, tigrillo, ocelote, birds, snakes, turtles and more. It is an interactive tour, wonderful!! Besides that is it great to know that what you pay, will be at the benefit of the local animals. People are very nice there, most of them work for a low salary or even as a volunteer because of their love for animals and nature.
Do not miss this!! and have fun.
