Chichen Itza was once the place where you could see grand old pyramids and climb to the top. Imagine the views up there! Travelers enjoyed that experience for hundreds of years without interruption. But eventually, the number of people curious about ancient stones began to get overwhelming. The Mexican government put a stop to it, in the interest of preservation. Unfair? We don't think so. Sad for wanderlusters? You betcha!
Rumor has it that graffiti was a concern. Or maybe it was simply too dangerous for so many people to climb up there. Who knows!
