About 2 hours outside of Cancun are the recently discovered and partially uncovered ruins of Coba. The temple there is taller than the one at Chichen Itza and the only one you can still climb on. It's not nearly as defined or as understood. The archaeologists believe that this ruin is older than Chichen Itza, dating before the Mayan encounter with the Toltecs, which changed their culture almost as drastically as the discovery by the Spainards.
Some of the tour group climbed, some of us remained safely on the ground.
One of the ruins in Coba. The site is only 10-20% uncovered and accessible to tourists. What remains hidden is still huge. Who knows what is there.
The stairs accessing the beach at Tulum. Built to allow foot traffic to one of the most beautiful beaches in the area, the stairs safeguards the ruins built at the top of the cliffs. The sand is like sugar, almost the same texture. There is quite a surf, crashing into the sand.
