Of all the sites, Chichen Itza is the one most closed off. If touching the ruins is important, skip it. There are barriers around most of them. https://www.tripadvisor.com/ShowTopic-g150812-i23-k4705866-Can_you_still_climb_the_steps_at_Chichen_Itza-Playa_del_Carmen_Yucatan_Peninsula.html
Why do women mess things up for the rest of us?
I was there in '03 and made the climb. It is quite dangerous; on the return trip. The 'steps' are QUITE tall and I came down by facing them and inching down each one, always keeping three of my hands or feet on them!
The owners decided to shut down the trail.
BTW; the woman was wearing high heels.
Sorry to hear they have xlosed so much of the Chichen Itza site. I got some great pixs from the top of the Pyramid back in the day.
Byt the eeriest part of the exploration was the descent into the interior of a pyrmid to a chamber with a statute of the Jaguar god. The passage way was very steeop and very small in diameter. Becaouse there was a long line of tourists going both ways, up and down, the oxygen was used up and it was hard to breathe. Great side trip from Cancun.
