Admission charge to the ruins is around 75 pesos. The evening sound and light show costs 35 pesos (add another 25 pesos for headphones if you want to listen to the commentary in English). The show usually starts at around 8.00pm, but we'd suggest you r-confirm the time when you arrive. Your ticket permits re-entry on the same day only.

At the entrance to the site is a large visitors’ complex, with cafeterias, restrooms, bookshops and a small museum. There are also models of the layout of the site. Note that there is a second refreshment shop with toilet facilities by the cenote.

History Chichén Itzá has been widely studied, and excavated and restored more than any of the other Mayan cities. Yet its history is still clouded in mystery and there are many contradicting theories and legends.

The Toltecs originated from Central Mexico, and one respected theory suggests that the Toltecs invaded Chichén Itzá and imposed their architectural style on new constructions. Alternatively, we know that the Maya traded extensively and it is possible that they were influenced by the Toltecs in their own architecture. Another more recent theory claims that Tula, capital of the Toltecs, was actually under the domination of the Maya, resulting in a transfer of style from one city to another. There are fragments of evidence to support each line of thought, but no conclusive evidence for any single theory.

Compounding the mystery are ancient legends passed down through the Mayan tribes and also the Toltecs. According to Toltec history, in 987AD the legendary ruler Quetzalcóatl was defeated and expelled from Tula. He was last seen leaving from the Gulf coast on a raft of serpents. However, in the same year, Mayan stories recorded the arrival of a king named Kukulkán, the Serpent God, whose return had been expected. Kukulkán defeated the Mayan city tribes, and made Chichén Itzá his capital.

The Pyramid of Kukulkán Towering above the other buildings at 79 feet (24 m) high, the Pyramid of Kukulkán has a structured feel about it. Two of its sides have been completely restored, the other two were left to show the condition before work commenced. Each side had originally 91 steps, adding the platform at the top as a final step there are 365 in total one for every day of the year. Further evidence that this building was linked to the Mayan interests of astronomy and the calendar is demonstrated at the spring and autumn equinox. On these days the shadow of the sun playing on the stairs causes the illusion of a snake processing down the pyramid in the direction of the cenote. Naturally, it’s an impressive sight, and there are usually thousands of people on the site at these times.

The Ball Court (Juego de Pelota) From the Pyramid of Kukulkán, head north-east to the Great Ball Court, the largest of its kind in the Maya world. There are eight other much smaller ball courts at Chichén Itzá and more in other Maya cities, but this one was deliberately built on a much grander scale than any others. The length of the playing field here is 40 feet (135 m) and two 25 feet (8 m) high walls run alongside the field.

The game itself involved two teams, each able to hit the ball only with elbows, wrists or hips, and the object was to knock the ball through one of the stone hoops on the walls of the court.

Look at the carvings on the lower walls of the court and you will see that this was not a casual sport there are clear depictions of one team member with blood spurting from his headless neck, whilst another holds the head aloft. Some people think the captain of the losing side was executed by the winner; others suggest that the winners earned an honorable sacrifice. No-one knows for sure. It is said that the game was used either as a method of settling disputes, or as an offering to the gods, perhaps in times of drought. Only the best were selected to play, and to be sacrificed in this way was a great honor.

Temple of the Jaguars and the Tzompantli From the ball court, head east across the central area towards the Group of the Thousand columns. On the way, you will see the Temple of the Jaguars with its friezes of the Toltec jaguar emblem, and the Tzompantli or Platform of the skulls. It is believed that the Tzompantli (a Toltec word) was the platform used for the sacrifices resulting from the ball game.

Sacred Cenote Before you reach the Group of the Thousand Columns, you will see a pathway heading north, just by the Platform of Venus. This is actually the route of an ancient sacbe, and leads to the Sacred Cenote.

A cenote is a sinkhole in the limestone bed, accessing an underwater river. These cenotes were very important to the Mayans as their main source of water and had great religious significance. Here you will see a deep almost circular hole with steep sides and murky green water beneath.

A stroll to the cenote is a pleasant diversion from the ruins and makes an ideal refreshment stop there is a small café/shop nearby and restrooms are available.

Group of the Thousand Columns After visiting the cenote, head back towards the Group of the Thousand Columns. This complex incorporates the Temple of the Warriors and a series of columns, some of which feature carvings of Toltec warriors. It is believed that the columns originally supported a thatched roof which may have been used as a market place.

The temple itself displays another aspect of Toltec architecture the use of ‘Atlantean figures’, or statues supporting the altar. Here the statues are of warriors, each with the appearance of a different racial type. It is unclear as to whether these designs were accidental or whether the Maya were really aware of the diversity of the human race.

Look also for the large Chac Mool sculpture, again a feature of Central Mexican rather than Yucatecan design. The reclining figure holds a bowl, awaiting some sacrificial offering.

The Caracol From the central plaza, take the path to the southern area of the ruins. This is thought to house the oldest constructions, and is predominantly Mayan in design.

The Nunnery (Edificio de las Monjas) and the Church (La Iglesia), both erroneously named by the Spanish, are in relatively poor condition. Look for depictions in La Iglesia of the four bacabs; these creatures (the crab, armadillo, snail and tortoise) were believed to be responsible for holding up the heavens.

The most impressive structure is the Caracol, named for its curved inner stairway reminiscent of a snail. Also known as the Observatory, this tower was used for astronomy its windows were aligned with the four cardinal directions and the position of the setting sun at the equinoxes.
