Chichén Itzá is a complex of Mayan ruins on Mexico's Yucatán Peninsula. A massive step pyramid, known as El Castillo or Temple of Kukulcan, dominates the ancient city, which thrived from around 600 A.D. to the 1200s. Graphic stone carvings survive at structures like the ball court, Temple of the Warriors and the Wall of the Skulls. Nightly sound-and-light shows illuminate the buildings' sophisticated geometry.
In addition to its beaches, one of the most popular attractions of Puerto Morelos is undoubtedly the Cenotes Route (Ruta de los Cenotes), which stretches across 21 miles, dotted with 60 of these mystical sinkholes that are connected to each other through the world’s longest underground river system: the Great Maya Aquifer.
