A question for anyone who would know the answer. I am hoping to climb Tacaná, which is the second highest volcano in Guatemala (and in Central America) this weekend. The volcano is right on the border of Guatemala (San Marcos department) and Mexico (Chiapas state). I would like to climb from Guatemala and descend into Mexico to get a nice round trip (since I don't have a car and there's busses everywhere in this part of the world it's very easy logistically.) Does anyone know if I would have trouble getting back into Guatemala, as the first time I would cross the border away from a legal border crossing? I know if necessary I could cross "illegally" again (the Guate-Mexico border does not compare, in any way, to the Mexico-USA border), but it would take longer and/or cost more.
Thanks for the help! P.S. If anyone who reads this has summitted Tacaná please message me as I have a couple questions.
