At Chichen Itzá, students encounter the impressive convergence of Maya architecture, mathematics, agriculture, astronomy, commerce, and religion. The Pyramid of Kukulcan, Temple of the Warriors, Observatory, and Ball Court help students appreciate pre-Columbian advances and restraints. Our excursion culminates with an optional swim in a beautiful cenote (natural pool). Cenotes were spiritually important to the Maya, and there are many theories about their significance to death rituals, fertility offerings, and a connection to the underworld.
