My usual confession. I have gone to lots of ruins and not fascinated by Mayan history. Bonampak is in the Lacandon jungle. Only the Lacandon people can bring you there so you must change to one of their jeeps For the last few kilometres.
Clearly great ruins but in a country with so many I preferred some of the others. These are all in one block so they seem small. The paintings which are still so colourful do make Bonampak a bit different. However, I preferred other sites, including nearby Yachchilan for atmosphere.
It is a real privilege in most of these sites to get up so close. You can enter the little rooms with the wall paintings and walk almost anywhere on the buildings. That wouldn't happen most places in Europe.More
