We woke up early and where there right at 9am (on a Tuesday) when the doors open. Admission was 80 pesos per person. We were asked to shower before going down to the Cenote. Getting all the way down to the Cenote was easy and there weren't too many stairs. We were the first people there so we got to enjoy it and take some pictures before the crowds started rolling in around 10am. The water was a perfect temperature and it felt like you were swimming in a pool. There are mini catfish swimming around, but they would disappear when we dove in because trust me they are more afraid of you than you are of them! Overall this was a great experience and I would definitely recommend making a trip to this Cenote and would suggest you go early if you want to have a peaceful experience.
