A tourist center with two magical cenotes.
To enjoy the place quietly, go there early in the morning, bus loads of tourists will arrive from 11 a.m.
I stayed in Valladolid, a "pueblo mágico", twice: through August 2013 and at the end of October, when I was going back to Europe. In both cases, my principal objective was to visit the cenotes in the area. The first time I came from the south, Mérida, (where I had visited other of these enchanting geological formations).
