While this may seem a strange title, so many things we visit are not as expected or don't appear as great as some artfully taken photos make out - such as the ancient pyramids of Egypt we found.
However! The Templo de Kukulkan will not disappoint!!
You can walk all around the 4 sides, however cannot get close enough to touch the stonework. Whilst 2 sides have obviously been restored (what you expect the pyramid to look like), 2 sides have not and we assumed had been eroded from the many years and many millions of pairs of feet that have gone up and down the many steps.
The other parts of Chichen Itza were a bit disappointing really... We actually preferred our visit to the ruins of Ek Balam (both reviewed separately).
