Hello River. Thanks for giving us your comments. Around the peninsula of Yucatan there are hundreds of cenotes, each one is different depending on different environmental conditions, age, and other external facts. The tastes of each cenote depend on each traveler. Our guides are certified to give you the best quality service without putting you at risk in each of the activities that are performed during the tour, it is important to follow their instructions to avoid any kind of accident, due to past situations is why we implement a collision insurance, which is not mandatory to purchase and this insurance is usually used by people who do not have any experience driving an ATV. We appreciate your understanding, have a nice day.
