1 hour car from the cruise port. Chacchoben is one of the most popular mayan ruin site in Quintana Roo state. It is a relatively recent discover. In fact it was sighted in 1972 during an helicopter flight by doctor Peter Harrison, an American archeologist. The Mayans established here around 200 BC and they built the structures around 700 AC. The ruins are being visited by tourists only from 2002. Guests can enjoy a circular track that is going around 3 pyramids and some more walls.
