After an early breakfast, we will start our trip to the Calakmul archaeological site, also a World Heritage site. Set deep in the tropical forest of the Tierras Bajas, a Biosphere Reserve, this important Mayan archaeological site played a key role for more than twelve centuries. Calakmul’s outstanding examples of Mayan art provide a testament to the city’s advanced political and spiritual development. After having a box lunch we will procede to Balamku, a site where we find a spectacular modeling stucco façade with policromy, dated at the end of the Early Classic period among 550 to 650 A.D. This frieze is considered one of the most beautiful artistic expressions in the Mayan low lands. Then we will return to Chicanna Ecovillage.
