AtlasAdventured recommends visiting this cenote!
Definitely one of the better cenotes in the area, both in quality and in value. You get two cenotes for the price of 1 and they didn't charge us for our 5 year old daughter. It's 300 pesos per person (about $15 USD) and gives you access to both. You can't buy single cenote access for a cheaper price. The ticket counter lady said we could walk to the other cenote across the main highway but recommended we drive. That was good advice because its across the street and down the road quite a bit. Probably a 30 min walk if you decide to go that route.
The first cenote we swam in is the one right by the ticket counter, Cenote Cristal. It's a large circular swimming area with steps to get in, a small rope swing and a large platform to jump off. There are many different seating areas along the edge of the Cenote and lots of shade from the trees. You will see many fish swimming around and someone said they saw a turtle but we didn't see it. Water is cool but refreshing on a hot day.
Cenote Escondido is long and has lots of seating along the ledge and at either end of the cenote . There's a rope swing and multiple spots to jump off. It's deceptively deep since the water is so clear and it looks shallower than it actually is. There were scuba divers at the bottom doing a training course or something and there was still enough depth to jump off the ledges. There was a large family and another small group of people there during our hour or two there so it wasn't too crowded. We had one end of the cenote, the large family had the middle area and the small group was at the other end. Make sure you are aware of those around you. Unfortunately we had a slight incident where my daughter and I were snorkeling in the very end of the cenote where nobody was jumping but apparently one of the dad's from the other group decided to run and jump off by us and landed right on my head while I was snorkeling. Luckily he didn't land on my daughter because I was in a lot of pain for the next couple of weeks unable to move my neck much. That cut our visit to this cenote short.
Besides that mishap, we had a great time and really enjoyed these cenotes. A great option during sargassum season to beat the heat and swim in some clear, refreshing water.
