Mexico's Best Ancient Ruins and Attractions
Ancient pyramids that were already ancient when the Aztecs found them.
Mexico's two headline ancient sites are Chichen Itza (a Maya city near Cancun, home of El Castillo pyramid, roughly $40 entry) and Teotihuacan (a pre-Aztec megacity near Mexico City with the massive Pyramid of the Sun, roughly $5–6 entry, and you can climb it). Both open around 8am; arriving at opening is the single best way to beat both the heat and the tour buses.
Mexico has two 'you have to see this at least once' ancient sites, and they're nothing alike beyond both being older than most countries currently on a map. Here's what each one actually delivers, what it costs in 2026, and the timing trick that makes or breaks the visit.
Questions people actually ask
Chichen Itza or Teotihuacan — which is better?
They're not really comparable — Chichen Itza is a Maya city near Cancun (a long day trip or overnight from the coast), Teotihuacan is a pre-Aztec megacity 45 minutes from Mexico City. If your trip includes Mexico City, do Teotihuacan; if it includes the Caribbean coast, do Chichen Itza. Plenty of longer trips do both.
Can you still climb the pyramids in Mexico?
At Teotihuacan, yes — you can climb the Pyramid of the Sun and (with a separate timed ticket) the Pyramid of the Moon's lower section. At Chichen Itza, no — climbing El Castillo has been banned since 2008 after a visitor died falling from the steps.
How early should I arrive to beat the crowds?
Both sites open around 8am and get seriously crowded with tour buses by mid-to-late morning. Arriving right at opening (or staying at a hotel near Chichen Itza the night before) buys you an hour or more of relatively empty ruins.
