I'm interested in a side trip to Amatenango del Valle. Are there combis in San Cristobal de las Casas that travel to Amatenango del Valle? I suspect that one could probably take a combi that is headed toward Comitan, it looks as though you would have to drive right through. It's also unclear to me if there are combis to Comitan. I'm aware of the first class buses, but I suspect they don't stop in Amatenango del Valle. Any thoughts?
