Chichen Itza activity and adventure holidays from the travel experts at Exodus Travels. Chichen Itza is the largest and most significant ancient Mayan site in Mexico. Chichen Itza, the most famous Mayan temple city, served as the political and economic center of the Mayan civilization. Its various structures - the pyramid of Kukulkan, the Temple of Chac Mool, the Hall of the Thousand Pillars, and the Playing Field of the Prisoners – can still be seen today and are demonstrative of an extraordinary commitment to architectural space and composition. The pyramid itself was the last, and arguably the greatest, of all Mayan temples. The ancient city is the jewel in the crown of the Yucatan Penninsula.
