There were 10 ziplines across the canopy of the jungle of varying length and intensity. I was only scared on the first lift off! As I was about to get clipped into the first line, I noted that my guide was wearing a simple wooden rosary. I jokingly asked if I could wear it. He immediately took it off and placed it over my head. I don't consider myself a religious person, but somehow I felt safer. After the ziplines were finished, I went to give it back the rosary and he said, "No, you keep it until the end of the day." I love those kinds of moments.
No pictures of the ziplines or ATV ride, but here is the amazing cenote. The water was so refreshing and clear. I've been to a bunch of other cenotes, and they are all different. Some dark and dank, amost spooky. Some deep in a cavern. This was one of the nicer ones.
There's a cliff that you can jump off. I did! It was one of the scariest things I've ever done in my life. Way more scary than The Hulk roller coaster at Universal Studios. No picture of me doing it, but here's a little video of my friends doing it. It's higher than it looks.
