If you are new to Mayan archeology then it is recommended to use a guide when visiting sites for the first time. Guides are provided at most sites in Spanish and English. German guides can be found through German agencies.
Guides must take a course and be certified to work as a professional guide at an INAH site. This is taken seriously and only under certain conditions will you get an uncertified guide. Hotels, resorts and fly-by-night operations generally provide uncertified guides. Sometimes, however, an uncertified guide is extremely knowledgeable.
Many guides have grown up in the area and know much about the plant and animal life. Many guides have been hunters and know the landscape well. Some guides actually live in the jungle while others live in nearby towns or cities. A guide who has grown up in the jungle, who still lives in the jungle can show you many interesting things and divulge many unique insights.
Each guide has their specialty, some know about what can be eaten in the jungle, some know about the rocks and minerals or animals, some are experts in ruins while others garnish a keen understanding of the area’s history.
