XKeken or Dzitnup. Swimming in a Cenote

After visiting Ek Balam we dropped our things off in Valladolid and went to visit the underground cavern known as Dzitnup or Xkeken. The water in the cave was beautiful and felt great as we swam in it. I heard many kids commenting that this was the coolest thing they had ever done. About 30 minutes into the swim the power went out in the cave. All of the sudden we were swimming in the dark. The only light came from the hole at the top of the cave. As we swam under the light it started to rain and a good amount came through the hole down into the cave. It was beautiful! A storm had blown down some trees and knocked out the power and that's why we were left in the dark. We swam for quite a bit longer after that until some guys came in and said it was time for us to leave. They were closing down the Cenote due to the storm. When we went down into the cave it was hot and sunny but when we came up it was cool and rainy with some really powerful thunder. I'm having a tough time posting pics but I'll do what I can.
