'Chichén Itzá is the largest of the archaeological cities of the pre-Columbian Maya civilization in the Yucatan Peninsula of Mexico. It is one of Mexico's most visited tourist destinations. It was granted World Heritage Site status in 1988 by UNESCO World Heritage Site and was recently selected as one of the New Seven Wonders of the World.
Many tourists visit Chichen Itza as a day trip, especially from Cancun, more than 100 miles away. This archaeological site is also an hour and a half away from Merida, the capital of Yucatan. The Maya communities near Chichen Itza have developed many wonderful sites for travelers to rejoice in the Maya Cultural heritage. It is recommended you avoid a day-trip visit to Chichen Itza and schedule a night or two to enjoy all the activities nearby. This allows time to see more than just a portion of this large site. If you stay a night here, come to the archaeological site early in the day before the sun is so hot, and before most of the day-trippers arrive. This is a large park and usually visitors are on a tight schedule, consider the services of a guide. They can be found in the museum at the entrance and are very nice and reasonably priced. If you tire of their company, they will not be offended if you mention that you would like to visit on your own. A guide can give you information on sleeping overnight at the site.
The site is open daily, 9-5. For entrance you have to pay 145 pesos of tax for Adult and 59 pesos for a ticket (May 7, 2014) and if you want to film with a video camera, you'll need to pay an additional 45 pesos.but it's free for taking photos.
Chichen Itza was a center of pilgrimage for the ancient Maya for over 1,000 years. The Sacred Cenote (a large natural well or limestone sink hole) was holy to the ancient Rain God "Chac".
About 987 the ruler of the Toltec people of central Mexico came here, and with his Maya allies made Chichen Itza the most powerful city in the Yucatan. The ruler called himself "Kukulcan", the name of the Mesoamerican Feathered Serpent deity (also known as "Quetzalcoatl") and Chichen Itza became a center for worship of that god as well. More buildings were built here in a mixture of Maya and Toltec styles.
About 1221 the Maya revolted against the rulers of Chichen Itza. The city was not abandoned, but as political power shifted elsewhere it declined and no major new buildings were constructed. Chichen Itza remained a place of pilgrimage for the Maya until it was conquered by the Spanish Conquistadors in the 16th century.
The structures of Chichen Itza were overgrown with jungle and slowly decayed until major archaeological projects began in the 1920s. Since then, more of the ancient structures have been cleared and restored and more and more tourists come to visit.
By road, Chichen Itza is on the main highway between the capital city of Mérida and the resort city of Cancun. If you have time and are looking for a more adventurist route, the "libre' road that runs parallel to the toll highway goes through and by many villages and gives a better feel for the area. If you take the "libre" route, you will need to be more alert for pedestrians and animals on the road, as well as the numerous "speed bumps" you will encounter. If after dark, stick to the toll road. Come by automobile or take the very regular bus service.
ADO bus service from Cancun costs 202 pesos one way trip and the trip takes three hours. You'll have about 4 hours to spend on the area if using the faster bus. A cheaper bus is available for 122 pesos and with travel time of four hours per direction. If you are visiting in transit between different accommodations there is free, well signed, baggage storage after the cashier on the right past the restrooms.
Update April 2015: prices went up to 220 mxn for foreigners.

Also, Chichen Services  which is dedicated to offer travel experiences dedicated to Sustainable Tourism and to financially help the nearby town residents with their community projects and endeavors.
At the site you get around on foot. Wear sturdy, comfortable walking shoes; consider that you may want to try climbing rough stone stairs in them. Sunscreen and a broad-brimmed hat may be good ideas too. There is very little usable shade in the middle hours of the day. Bring a pair of binoculars, star-gazing and birding is incredible in this region. Also, if you want to know more about the Mayan local communities, their cooking, religious rites, calendar system and ancient arts, visit the small towns around Chichen.

"Tales of the Maya Skies" - this is a dome planetarium show produced by the Chabot Space & Science Center in Oakland California. It is shown in English and Spanish (alternating) at the Mayaland Hotel. The "Mayan Planatarium" is a new building completed just in time for the celebrations of 12/21/2012; the building is modeled on the Caracol (the observatory) as depicted in the show. Contact the Mayaland for show times. Visit http://mayaskies.org for details about the show.
Be sure to drink lots of bottled water. Those not accustomed to the tropical heat and sun can otherwise risk dehydration.
There are several refreshment stands in the archaeological site.
There are a handful of hotels by the ruins, along the highway nearby, and in the nearby town of Piste, in a variety of price ranges. Some have good swimming pools and restaurants. The town of Valladolid, 40 km away, is a less-touristed alternate base.
When dealing with vendors; Many will say "Only 1 dollar" or "1 Peso", please do not assume that is the actual price of items they are selling. Once you try to complete the transaction it will be actually 1 dollar off or 1 peso off and you will be ask to further "negotiate" with them. This might delay you unnecessarily if you are with a tour group. Don't be afraid to walk away, they will follow you with a better offer, they enjoy the challenge, it's Mexico!!!
If on a tour, note that prices at a souvenir stop will be much more expensive than those offered by other vendors. Regardless, souvenirs will still be cheaper than those found in Cancun.
If visiting during the rainy season, consider bringing an umbrella and/or a rainjacket. Otherwise, vendors will sell plastic ponchos for $5 USD or 50 pesos. However, the rain comes and goes quickly, so it may be worth it to just tough it out.
Be sure to have cash pesos; changing money may be difficult here, especially on weekends.

Tripods are forbidden unless you obtained special permits months ahead of time.
