I have not been to the Maya parts of Mexico since 1992, when I traveled to the Yucatán Peninsula with Martine and several co-workers at Urban Decision Systems. Now I am thinking of going again. My January trip to Guatemala only whet my appetite for more.
On past trips, I have seen the ruins at Chichén Itzá, Uxmal, Dzibilchaltun, Acanceh, Mayapan, Palenque, Tulum, Kabah, Labna, Sayil, and Xlapak. I would not mind seeing Chichén, Uxmal, and Palenque again, and perhaps even spending a little time at Valladolid and Izamal, which I have not seen. New destinations would include several Maya ruins in the State of Campeche, most notably Calakmul and Edzná, and Bonampak and Yaxchilán in the State Of Chiapas. The latter two can be seen on a tour from Palenque.
The most problematical destination is Calakmul, which may possibly have been the largest Maya city at one time—perhaps even bigger than Tikal in Guatemala. The problem is that the southeastern edge of the State of Campeche has not yet been sufficiently developed for tourism by the Mexican government. I can possibly get a tour from either the city of Campeche or of Chetumal in Quintana Roo.
There is also the possibility of Cobá in Quintana Roo. I might visit it if I have to go to Chetumal to set up a tour for Calakmul. Otherwise, I would be reluctant to run into the passenger ship mobs that dock at Cancun and the Maya Riviera.
Two cities I would love to re-visit are Mérida in Yucatán and Campeche in the state of the same name. Both are delightful places that positively reek of contemporary Maya culture, with hints of the Mexican mestizo culture and—oddly—an admixture of Lebanese and Syrian, due to the merchant classes that set up there in the 19th Century.
