In the Llanos de Moxos there are more than 20 thousand artificial hills, hundreds of kilometers of ridges or dikes and other expressions of an ancient formidable technology of control and exploitation of floods. Our tour includes a presentation onboard about the latest archeological discoveries in the region as well as walks to the pre-Columbian mounds where we will find all kinds of buried ceramic fragments along our paths. A visit is recommended to the Kennet Lee Archaeological Museum, before embarking, which offers well-explained information and images about this incredible "agricultural hydraulic culture".
