My family and I recently went to Jardin del Eden cenote which is close to Puerto Aventuras. We had a car so we drove in. The road is a bit rough but after paying $6 per adul and $4 per child we made it. The cenote is probable 5 minutes of the road. Facilities are rustic, there are some thatch huts under which one can just find shade or have a little picnic. The cenote itself is beautiful. It is deep and the water is refreshingly cool. In a couple of spots inside the cenote there are some huge boulders where one can sit on top of and take in the scenery. My family and I jumped off the cliff and off the tree, it was quite a rush! They have lifeguards on site. There were some scuba divers that went into the cave under the cenote. Looked like a great experience.
