Getting there:
I won't be much help here since I am not from Mexico, but I know it was located off the main road through Tulum.
Experience:
If you visit Tulum, this is a must do. I was a little skeptical at first because I was thinking, "swimming in dark caves, seems a little sketch," but I was so glad I did it. Also, they have lighting inside the caves. Our tour guide Carla was so awesome. She made us all feel safe and welcomed, and we were able to hangout with her like she was a part of our group of girls for the day.
First, they make you rinse off any sunscreen or oils you may be carrying on your body (to preserve the caves is my guess). Then they take you to a small area where a man asks mother nature for permission to enter into the caves (really cool). So we were taken into 4 cenotes. The first one we repelled down into. It seems scary at first, but I promise it is not at all. The second one was a fully open cenote and the third and fourth were completely underground, but again they have lighting so it's not scary.
This was probably a once in a lifetime opportunity, and it was such a blast and so cool to see how the caves have eroded over time. I fully recommend. (I apologize as I didn't grab any pictures inside the 4th cenote.) read more
