Chichen Itza stands as a crowning jewel of Mayan culture in the Yucatan Peninsula, boasting some of the most astonishing architecture among ancient Mayan cities. It's the largest and most awe-inspiring of the Mayan ruins. If your itinerary allows for only one day trip from Cancun, make it this one. The grandeur and mystery of Chichen Itza are simply unmatched. The name Chichen-Itza, pronounced "chee-chehn eet-sah," translates to "Mouth of the well of the Itza" in the Mayan language. This sacred city, located 75 miles east of Merida, the capital of Yucatan, Mexico, spans roughly six square miles. Once upon a time, hundreds of buildings adorned this landscape. Today, while many remain as mounds, over thirty structures are still visible to curious travelers. Chichen Itza's ruins are divided into two distinct groups. The first group hails from the classic Maya Period, constructed between the 7th and 10th centuries A.D. During this time, the city rose as a prominent ceremonial hub. The second group represents the Maya-Toltec Period, extending from the late 10th century to the early 13th century A.D. This area features the Sacred Well and many of the site's most remarkable ruins. For those with a penchant for history and architecture, the Temple of Kukulkan, also known as El Castillo, is a must-see. This pyramid is not just an architectural marvel but also a testament to the Mayans' astronomical prowess. Twice a year, during the spring and fall equinoxes, a shadow resembling a serpent slithers down its steps, a phenomenon that attracts visitors from around the globe.
