La Mesilla is the Pan-American Highway crossing between Guatemala’s Huehuetenango department and Ciudad Cuauhtémoc in Chiapas, Mexico: the road border for San Cristóbal de las Casas and Comitán. The IGM tariff lists no routine land exit fee, and Mexico’s Ley Federal de Derechos exempts land stays of seven days or less from its visitor fee (Art. 11, fraction II a; IGM tariff read 27 October 2026, Mexican law read 4 November 2026). Three sellers run weekday tourist shuttles that change bus at the line.

Quick summary

  • Where: Guatemalan customs sits at Km 336 of the CA-1, Aldea La Mesilla, in the municipality of La Democracia. The Mexican side is Ciudad Cuauhtémoc, municipality of Frontera Comalapa, Chiapas.
  • Hours posted: Guatemala customs 06:00-21:00 daily; Mexico’s garita at the line 06:00-22:00 daily. Only a 2021 IGM directory lists 24-hour Guatemalan migration service; none of the current sources we read on 25 October 2026 confirms it.
  • Fees: the IGM tariff lists no routine land exit fee (read 27 October 2026); Mexico’s Ley Federal de Derechos exempts land stays of 7 days or less from its visitor fee and sets MXN 983.00 for longer stays, paid on exit (read 4 November 2026).
  • Shuttles (Mon-Fri): Antigua to San Cristóbal USD$70-80, Panajachel USD$55-60, Xela USD$60, with a bus change at the border.
  • Warning: the UK Foreign Office advises against all but essential travel near this border on both sides.

How to read this. Among the current sources we read, the only hours that cover every day are the Guatemalan customs window (06:00-21:00) and the Mexican garita (06:00-22:00). INM’s published office hours are weekday business hours; we found none published for the migration filter itself. Cross on a weekday, in daylight. The CAIT at La Trinitaria is an inland checkpoint on the road to Comitán, so keep your passport and entry paperwork where you can reach them after the border too.

Documents and fees

  • Fees: Guatemala charges no exit fee: none of the border-control lines in the migration tariff in force (Acuerdo IGM-029-2023 as reformed by IGM-039-2025, Art. 3, numeral 4.2) is one, and if you stayed past your authorised time, the overstay fine is due on the way out. The same numeral also lists document services that are not exit fees, such as replacing the entry stamp in a valid passport (USD 10). Mexico does not charge its visitor fee for land stays of seven days or less: the exemption is in the Ley Federal de Derechos itself (Art. 11, fraction II a), which the reform published on 7 November 2025 left unchanged while setting the fee at MXN 983.00 for 2026 (Art. 8, fraction I); above seven days the fee is paid when you leave Mexico (read 4 November 2026). Amounts and caveats: border-run costs page.
  • Tarjeta de Visitante Regional (TVR): free, valid 5 years, for nationals of Guatemala, Belize, El Salvador and Honduras and for foreigners who are permanent residents of those countries. It allows visits of up to seven days to Campeche, Chiapas, Tabasco, Quintana Roo and Yucatán, and is issued at the southern entry points on a passport, personal identity document or identity-and-travel document (original and copy), with biometrics and an interview. It does not allow paid work. Minors also need a birth certificate issued no more than six months earlier and permission from their parents or legal guardian granted before a notary or justice of the peace; foreign residents of those countries also show the document proving their permanent residence.
  • FMM online: INM’s portal lets foreigners entering by land fill in the FMM before the trip, but the form is released only after the fee is paid on INM’s services portal. If your stay is seven days or less and therefore fee-free, the online route is built for people who pay; deal with the form at the INM post instead, and ask there.

What one shuttle seller tells its customers, and how it contradicts itself. Adrenalina Tours’ notes for its San Cristóbal shuttle give two different Mexican exit amounts in pesos (one said to apply whatever the length of your stay, the other only to stays longer than seven days) and a separate quetzal payment at the Guatemalan border. The two peso amounts contradict each other, and none of the three charges appears in the official texts above. If you are asked for money, ask for the official receipt.

Guatemala Transportation marks its San Cristóbal and Comitán products “bus change at the border”. AtitlanTour gives Xela to San Cristóbal as 9 hours.

What the San Cristóbal shuttle is really like, in the seller’s own words. Adrenalina Tours publishes an unusually frank list: the service is subcontracted; the buses are mostly old, with little legroom; punctuality is not guaranteed; all seats are used; from Antigua you change bus at La Cuchilla (joining the bus from Panajachel) and again at La Mesilla (the bus from Mexico), with stops at Cuatro Caminos and Huehuetenango; and the driver is not a guide. It tells you to budget 13 hours from Antigua, 12 from Panajachel and 10 from Xela, and warns that roadblocks between San Cristóbal and the border are frequent, with any extra cost on you. Its notes mention a 5:30 am start from Antigua while its timetable says 03:30, so be ready for the earlier time.

By public bus. Take Los Halcones from Guatemala City to Huehuetenango (six hours as published). No operator we read publishes a Huehuetenango to La Mesilla timetable or fare, so ask at the Huehuetenango terminal.

Huehuetenango to San Cristobal de las Casas

Guatemala Transportation lists a weekday offer; Adrenalina Tours also lists this route on its historical Huehuetenango page (read 25 October 2026). These are advertised offers, rather than confirmation of seats for a travel date.

Adrenalina Tours describes drop-off at the zócalo in San Cristóbal de las Casas, rather than door to door.

Coming back from Mexico

Guatemala Transportation lists San Cristóbal de las Casas departures Monday to Friday: to Panajachel USD$60 (06:00, 11 hours) and Xela USD$60 (06:00, 13 hours), and to Antigua USD$75 and Guatemala City USD$100 (14.5 hours, minimum 2 passengers) with no time given. AtitlanTour lists the same 06:00 departures to Panajachel (USD$60, 11 hours), Xela (USD$60, 9-10 hours) and Antigua (USD$75, 13 hours). Adrenalina Tours’ fares from San Cristóbal back to Antigua and Guatemala City, and its 02:30 Guatemala City departure, are compared on Antigua to San Cristóbal de las Casas.

Driving across

SAT’s directory lists only goods clearance (import, export and transit) among La Mesilla’s services. Its entries for Tecún Umán II and Melchor de Mencos, by contrast, list Permisos de Turista (tourist permits) without saying whether that means vehicles; only El Ceibo’s entry says Vehículos de Turista. If you are driving a foreign-plated car into Guatemala, confirm with SAT that a vehicle permit is issued at La Mesilla before you plan on it; our foreign-plated vehicle guide covers the Guatemalan permit.

Safety

  • UK Foreign Office (Guatemala): it advises against all but essential travel within 5 km of the Mexican border from the Pacific coast up to and including the Gracias a Dios crossing, citing gang-related violence along the border. La Mesilla is inside that band. It also names the town of La Democracia, together with Santa Ana Huista and San Antonio Huista; SAT’s address places La Mesilla, a village (aldea), in La Democracia municipality.
  • UK Foreign Office (Mexico): it advises against all but essential travel within 40 km of the Guatemalan border in southern Chiapas, up to the Gracias a Dios crossing, and against Federal Highway 199 between Rancho Nuevo (outside San Cristóbal) and the Chancalá junction near Palenque, where illegal roadblocks are frequent.

What is not published

  • Current confirmation of Guatemalan migration hours: the historical IGM directory issued 31/01/2021 lists Monday to Sunday, 24 hours a day (read 25 October 2026).
  • Hours for INM’s migration filter as opposed to its weekday public office.
  • A Huehuetenango to La Mesilla bus timetable or fare.
  • A walking distance between the two countries’ offices from any official source.
