Cenote question

I went on a cenote trip when staying in Merida. The hacienda where I stayed, Hacienda San Pedro Nohpat, the owners, Canadians,
set me to the Cenotes of Cuzama. There you take a horse and cart ride down the old little train tracks to three different cenotes. The
adventure was one I will always remember and was very cheap. I believe the guides have life jackets for people to use, but even if you do not swim the trip is still worth taking. If you check out www.haciendaholidays.com they have more info on cenotes.
