My favorite cenotes are near Tulum and Puerto Aventuras called Garden Of Eden and Crystalino. You pay about 35 pesos to get in to a little, old lady in a shack. On a hot summer day the water is colder than the ocean. Super clear water that you can see the bottom even at 50 feet deep. I miss cenotes. In April all the rubber trees have orchids growing on them and thousands of colorful migrating birds of every color. Watching them fly looks like red, blue and yellow clouds.
