El Tajin (El Tajín) is in the state of Veracruz in Mexico. It is a UNESCO World Heritage Site.
El Tajin, Totonac for 'thunder' or 'lightning', is a group of sacred buildings where ceremonies and religious sporting events were held. First begun around AD 100, it was occupied and developed mainly around AD 600 to 900, and later abandoned. El Tajin was rediscovered by the Spanish in 1785.
There are a large number of remaining edifices to be seen, some include multilingual information stands. Voladores (flyers), who ascend a tall pole and spin slowly to the ground while attached to ropes while meditating, can be seen outside the complex.
Wearing a hat is a good idea as the jungle temperatures and sunshine can be draining.
Cheesy souvenir stands surround the complex, along with a few restaurants. There are no hotels but the site is near Poza Rica, Papantla, or the small beach resort of Tecolutla. The site is popular with tourists and can be crowded on some weekends.
There is a small charge for entering the grounds. Voladores performances are free but it's always good to aid the performers with a donation.
