The 1st city that we visited was Palenque, my absolute favorite Mayan city :-) We had a little adventure getting our Passports and Visas stamped; after that things got easier. We got to our hotel near the ruins and relaxed. Unlike previous visits, I did not feel the urge to visit every temple.
On December 21st, the Winter Solstice, the sky poured rain like I have never seen before. Several groups came to Palenque to chant and pray and hold ceremonies. Despite the weather, I had a great (albeit wet) experience.
For more photos of Palenque, see our 2005 trip to Chiapas, 2008 trip to Palenque, and my 2010 trip to Chiapas.
