Crossing Mexico from Guatemala
 

Hi there! I am planning a trip with my son starting in Guatemala and ending up in Canada, through Mexico and USA. I am a little concerned about riding Mexico and the USA border. Any comments as well as recommendations will be welcome. Thanks!

From Guatemala to the USA you have several options for border crossings into Mexico. The least hectic border crossing into Mexico would be El Ceibo up in the Peten, Very calm crossing, open from 6am to around 8pm. Then ride to Tenosique and whatever route you wish .
Getting the Mexican TVIP for a bike or car may still be difficult at El Ceibo on any Monday when the Banjercito man haas his day off. , but other days it should be easy.
The Crossing of the Panamerican Highway at La Mesilla to Cd Cuauhtemoc is a bit of a mad house, very crowded street scene at the GT border exit.Open from 6 am to 9pm . The Mexican customs post for that border is actually 4km north at the bottom of the mountain in Cd Cuauhtemoc town.
Down on the coastal strip the crossing to Cacahoatan northeast of Tapachula is also fairly tranquil now that most heavy truck traffic gets directed to the more southern crossing at Tecun Uman. You can get your Mexican bike papers at the new roadside terminal o Mex 200 near Huixtla .about 40km into Mexico

For entry to the USA you have loads of good options, really any crossing from Mexico to the US is acceptable and easy enough.... as long as you have all your paperwork and visas in order.US customs are real sticklers for those kinds of things
Enjoy your planning and your trip
