Pati's three sons are in Mexico and Pati wants them to experience the essence of the Yucatan. First stop, they climb the ancient ruins of Uxmal and discover how advanced the ancient Maya civilizations were. After an exhaustive exploration, the boys cool off in one of the thousands of hidden cenotes (swimming holes). To fill their bellies, the boys eat the best tamales they have ever tasted and the regions signature dish, cochinita pibil, which uses the ancient technique of cooking the meat with heated rocks buried underground.
