Cenote Ik Kil is a very large sinkhole located near Merida on the Yucatan Peninsular in Mexico. It costs 80 pesos to enter and then you pay additional for lockers and lifejackets if you need them.
The Cenote is by far the best Cenote we saw during our Mexican visit. This massive limestone sinkhole is draped with vines and tree roots hanging down from the ceiling. The sun shines through the mouth of the sinkhole as water trickles down. It is stunning.
Yes, it does get crowded, we were blessed that we had a thirty minute gap were the numbers were not so great so we could float and really enjoy the moment.
An absolute must experience location.
