Your encounter with the Maya culture starts with a 1,500 year-old historical journey to the ancestral city of Coba, an archaeological site hidden deep inside the rain forest of south-eastern Yucatan Peninsula. The Mayan Ruins of Coba are one of the most important archaeological sites in the area and not frequently visited by tourists. Built between two lakes, it was at one time a very large city spread over 80 square kilometers (49 miles).
