How We Infiltrated Mexico Twice from a National Park (And Why You Should Too)
A Complete Guide to Crossing into Boquillas del Carmen from Big Bend — With Burros, Bureaucracy, and a Four-Year-Old in Full Firefighter Gear
I have now led my family across the Rio Grande into Mexico twice. Once on a spontaneous Sunday in 2019, in the middle of a minivan circumnavigation of the United States, with three boys, no plan, and a four-year-old dressed head-to-toe as a firefighter. And once in 2022, without our beloved overloaded skoolie (converted school bus), which had been diplomatically informed by the Mexican border that its presence was not required.
Both times were absurd. Both times were wonderful. Both times ended at a video kiosk where a U.S. Customs officer in El Paso had to compose himself before clearing us back into America.
This is the story of both crossings — and everything you actually need to know to do it yourself, ideally with fewer parasitic worm concerns and more functioning burros than we managed.
What Is Boquillas del Carmen, and Why Can You Enter Mexico Through a National Park?
Boquillas del Carmen sits on the banks of the Rio Grande in the Mexican state of Coahuila, tucked against the southwestern end of the Sierra del Carmen mountain range. It is one of the most isolated inhabited places in North America — the nearest city of any size, Santa Rosa de Múzquiz, is 240 km (150 miles) south on roads described diplomatically as "second-class," a journey of at least four hours. There is no mobile data. For years there was a single landline, operated on a callback system: you'd call, leave a message, and an operator would physically go find the person you wanted to speak to, then ask you to ring back at a set time. This is either charming or maddening, depending on your personality type and how urgently you needed to speak to that person.
The village was founded in the late 19th century when silver, lead, and zinc were discovered in the nearby Sierra del Carmen mountains. At peak operations, somewhere between 2,000 and 4,000 people lived here. Mining stopped in 1919, the population collapsed, and Boquillas reinvented itself around the only industry available: tourists from Big Bend National Park crossing the river for tacos and cold beverages. Jose Falcon's restaurant opened in 1974 and has outlasted mining booms, a decade-long border closure, a global pandemic, and whatever it was we put it through in 2019.
By 2000, about 250 people called Boquillas home and roughly 15,000 visitors crossed the river annually. Then September 11 happened. In May 2002, the Department of Homeland Security closed all informal Rio Grande crossings. The population dropped to around 70. Half the village simply left.
It took over a decade, a presidential agreement between Obama and Calderón, and some genuinely creative federal bureaucracy to fix it. On April 10, 2013, the Boquillas Port of Entry officially reopened as a Class B crossing — the only unstaffed legal border crossing between the United States and Mexico. Re-entry is handled by a self-service kiosk and a video call to a CBP officer in El Paso. You can arrive by burro. This is legal. This is perhaps the finest sentence in the entire U.S. Code of Federal Regulations.
The First Crossing, 2019: The Minivan, the Manure, and the Mutiny
We were in the middle of a minivan circumnavigation of the United States — our family of five, a Honda Odyssey, and a budget so lean it would make a Trappist monk wince — when Heidi spotted Boquillas del Carmen on the Big Bend park map while we were obtaining our backcountry camping permit. I was busy debating the 4WD capabilities of our Honda Odyssey with a ranger who was clearly trying not to laugh. The ranger had more pressing news.
"The border'll be open till five," he said. "Once it closes it's closed till Wednesday."
It was Sunday. Heidi processed this information for approximately one second.
"Time's wasting, everyone make for the minivan!"
The drive to the Boquillas Crossing from Rio Grande Village — about 1.5 miles east — is the kind of thing that feels too easy. You park. You walk through a small border station. A dirt path leads toward the river. And there, lying between you and Mexico, is the Rio Grande, which looked, on this particular afternoon, to be about knee-deep.
Heidi and I exchanged the look that all long-term traveling couples develop: the silent, rapid-fire negotiation that contains multitudes. In this case it contained: $5 a head times five people is $25, and we are living on $40 a day.
A responsible decision was reached. Heidi would take the boys — Kai (11), Cove (8), and Zev (4, in full firefighter turnout gear, as was his custom) — across in the aluminum rowboat for $5 per person. I would ford the river like a pioneer. Or a man who had done math and arrived at a conclusion that seemed reasonable at the time.
I removed my shoes and socks, rolled my pants to the knee, and waded in. The bottom was pebbly, the water clear, and for approximately forty feet I felt genuinely heroic. By mid-river — which, I had been informed, is technically the U.S.-Mexico international boundary — the water reached my thighs. There were dozens of eyes watching from the Mexican bank. Heidi and the boys were already across. I increased my pace for the audience.
This was a mistake.
As I reached the far bank, my foot descended not onto rock but into something that can only be described as a warm, grasping biological paste. A gooey mixture of river silt and what was plainly donkey manure locked around my feet and ankles with the grip of a slow-motion catastrophe. I stood there, shin-deep in the mire, and did what any rational person does in that moment: I catalogued every parasitic worm I had ever read about. The little ones. The ones with the Latin names. The ones that pierce soft skin and make straight for the liver. The ones that appear in case studies with titles like "Unusual presentation in an otherwise healthy adult male." On my gravestone, I thought, the inscription would read: He Saved Five Bucks.
A stocky man in a large cowboy hat, watching from the bank, took mercy on me and gestured upstream toward the rocks. I backtracked through the biological hazard zone, reached solid ground, and rejoined my family. They were absolutely fine. They were also smiling in a way that suggested the next few minutes of my life were already being formatted for future dinner party use.
The Burro Situation
On the Mexican bank we were met by approximately thirty burros, a couple of dust-covered pickup trucks, and fifteen caballeros who materialized from the desert scrub with the practiced efficiency of people who have done this many times and find it entirely normal. A couple we'd seen cross just before us was already vanishing into the mesquite in a truck, enveloped in a photogenic cloud of dust.
The caballeros closed in. "You ride truck?"
"No gracias." (Respiratory health of offspring. Concerns noted.)
"You ride burros?"
Now here was a proposition. Heidi — who had not come all this way to put her children in a dusty pickup when there were tiny donkeys available — entered negotiations with the confident fluency of someone who has bartered at many markets on many continents.
"Dos burros, para los tres hijos."
The caballeros conferred. Two burros, three riders, $10. They shrugged, loaded Kai onto one burro, wedged Cove and Zev onto another, accepted our money, and delivered a firm swat to each animal's flank.
The burros departed.
Heidi and I looked at each other, then at the retreating caballeros, then at our children, now disappearing down a desert track at burro-pace on unsupervised livestock.
"Do they think we know what we're doing with these things, or where we’re going?" Heidi asked.
"I hope the burros can help with the latter," I said.
(We would later learn the standard rate is $15 per burro — with a guide. We had purchased the bargain option. The option without the guide.)
For a while, everything was magnificent. Kai on his burro, hollering "Yaaaa! Yaaaa!" and attempting to pull ahead. Cove holding the reins and laughing with his whole body. Zev perched behind Cove, smiling in full firefighter regalia — helmet, turnout coat, boots — looking like the world's smallest and most prepared emergency responder. Heidi and I walked behind, snapping photos and upgrading our assessment of the $10 investment to Best Money We Have Ever Spent.
Then the lead burro stopped.
Not slowed. Not hesitated. Stopped. A full, dignified, zero-explanation halt. A split second later, Cove and Zev's burro walked nose-first into the leader's rear end. Both animals stood motionless, staring at nothing, in the way of creatures who have made a decision and are at peace with it.
"Yaaaa, Yaaaa!" Kai tried, flopping his feet. Nothing.
I took the reins of the lead burro and leaned into them. The metal bit scraped between the animal's teeth. Feeling barbaric, I stopped. I turned instead to the full arsenal of my Spanish command verbs: "¡Vaya! ¡Venga! ¡Ándale! ¡Corre! ¡Adelante! ¡Arriba!" I accompanied each verb with what I hoped were universally understood forward-motion gestures.
The burro considered this. Then, having weighed the evidence, it formed a new theory: these people were on the wrong side of the Rio Grande, and it was the burro's civic duty to correct the situation. It turned around. The second burro, displaying the herd loyalty of the deeply committed, turned too. Both animals began walking our children back toward the United States.
My wife, I should note, was incapacitated. Not with alarm. With laughter. Tears. The full convulsive variety. She was also filming.
I managed to wrestle the lead burro to a halt, but could not simultaneously stop the second, and the leader immediately resumed its unauthorized repatriation mission the moment I turned away. I needed two sets of hands. I had one. The other set was documenting the situation for posterity.
Salvation came around the bend in the form of a middle-aged caballero, leading a string of burros, each carrying a tourist who appeared to be having a considerably smoother experience than we were. I called out a greeting. He smiled warmly, waved at our tiny Fireman, and continued on his way — because what I had failed to do, in the crucial moment of greeting, was actually communicate our situation.
But what I missed, the boys had caught. The caballero had been clicking — a specific tongue-to-roof-of-mouth sound. Kai, eleven years old and apparently gifted with faster language acquisition than his father, reproduced it perfectly. The lead burro, which had been immune to every Spanish command verb in my vocabulary, heard that click and started walking.
We made it to Boquillas.
The Village
We tied our burros to a scrubby tree with long branches that served, evidently, as the official burro parking lot, and walked up the dirt road that was Main Street. At the first house, a white cloth was strung between two trees, two words embroidered on it: No Wall. More signs followed as we walked deeper into the village. The same words, the same quiet insistence.
The stakes are not abstract here. In May 2002, when the border closed after 9/11, tourism — the primary economic activity for the village — vanished overnight. Half the residents left. The population dropped below 100. That two-word sign isn't political decoration. It's a community's understanding of what it nearly lost.
We ate at Jose Falcon's. We bought things from the honor-system craft displays along the road — handwoven blankets, embroidered textiles, wire sculptures — where you take what you want and leave cash in a jar. In a place this remote, with no oversight and no enforcement mechanism, this system works. I find this quietly extraordinary every time I think about it.
On the walk back to the crossing, Zev delivered his field report:
"They really like firemen here."
He wasn't wrong. Los Diablos — a wildfire crew of around 32 Mexican nationals who live in Boquillas and cross into the United States to fight wildfires in Big Bend National Park — are genuinely beloved. In a village of 150 people, running an elite international firefighting operation is not a small thing. It is extraordinary by any measure. Zev, who had spent the entire day in full turnout gear, was presumably understood by the villagers to be some kind of advance scout.
Re-Entry: Entertaining Federal Agents
Back at the Boquillas Port of Entry, we scanned our passports at the self-service kiosk. The screen connected us to a CBP officer in El Paso — over 300 miles away — who appeared on video to confirm our identities and wave us back into America. This is the future of border security, apparently, and it works remarkably well. Heidi spoke to the agent, answered his questions, and then went quiet. She was just standing there, holding the handset, not talking.
"What's the look about?" I asked.
"He was laughing," she said. "The whole time I was talking. Couldn't control himself." She handed the phone to Zev. "He said he needed to speak with the fireman."
The Second Crossing, 2022: Plan B (Base Camp Sits This One Out)
Three years later, we were back at Big Bend — this time with Base Camp, our beloved and aggressively overbuilt camper van, which had been with us through deserts, mountain passes, and one memorable incident with a low-clearance parking structure that we do not discuss. We had ambitious plans to drive Base Camp into Mexico. Mexico had other ideas. Base Camp, it turns out, significantly exceeded the weight and dimensional tolerances of the border crossing infrastructure on the Mexican side. This was communicated to us at the U.S./Texas side of a different border crossing, after we had driven a very long way through very flat Texas to get there. You can read about that misadventure in: Denied Entry to Mexico in a School Bus: Two Border Crossings, Zero Stamps, One Hard Lesson
We drowned our sorrows in emergency guacamole at a Mexican takeout joint on the U.S. side. Then we hatched Plan B.
We would leave Base Camp at Big Bend, drive to the Boquillas crossing, and do what we'd done in 2019: walk in on foot, cross by rowboat, and let Mexico come to us rather than trying to force four tons of camper van through a gap it was not designed for.
This time we had the advantage of experience. We knew about the burros, the honor-system crafts, the tacos, the single-landline callback phone system, and the importance of arriving before the border closed. We also knew to stay out of the mud at the river's edge. This felt like growth.
The crossing was everything we remembered: the absurd simplicity of it, the $5 rowboat, the burros standing around looking philosophical, the Sierra del Carmen mountains going pink in the afternoon light above the village. Jose Falcon's was still there. The honor-system craft displays were still on the road into town. The No Wall signs were still there too.
We rode the burros. They cooperated this time, because the boys had not forgotten how to click.
Your Complete Guide: How to Do This Without Our Mistakes
Getting There
The Boquillas Crossing Port of Entry is inside Big Bend National Park, about 1.5 miles east of Rio Grande Village. Rio Grande Village itself is 21 miles southeast of the park's Panther Junction headquarters — a drive that drops nearly 2,000 feet from the high Chihuahuan Desert down to the Rio Grande, with sweeping views of the Sierra del Carmen looming across the border. Free parking at the crossing. No drama getting there. All the drama comes later.
Hours (Check Before You Go)
The crossing operates seasonally. November through April: Wednesday–Sunday, 9 AM–4 PM. May through October: Friday–Monday, 9 AM–4 PM. Arrive back at the U.S. side at least 30 minutes before closing — the doors lock promptly, and the person who missed the last ferry at a genuine international border will have a very specific kind of bad afternoon. Confirm current hours at nps.gov before you go, as they do adjust.
Documents
Bring a valid U.S. passport or passport card. Non-U.S. citizens need a valid passport and must be registered with ESTA. There is no flexibility on this. A remote desert crossing on a Sunday afternoon is not the moment to discover your passport expired.
Crossing the River: $5 vs. Free (Choose Wisely)
The rowboat is $5 per person, round trip, operated by local villagers. This is the correct choice. The money directly supports around ten families. Tip on top of the fare. The "wade across for free" option is available when water levels are low. Having done it once, I can confirm it is genuinely fine — provided you approach the far bank via the rocks and not via the section that is, empirically, a donkey toilet. Both banks of the Rio Grande look similar from mid-river. They are not similar.
Getting to the Village
The village is about a half-mile from the river. Walk it, or ride a burro, horse, or catch a truck. The current rate for a guided burro ride is $15 per burro. If you attempt to negotiate this down to two burros for three children with no guide, I respect you, but document what happens when the burros stop. The clicking command is: tongue pressed to the roof of your mouth, released sharply. Practice before you go. Your 11-year-old will get it faster than you.
Mexican Immigration
Present your passport at the Boquillas immigration office. You'll get a Forma Migratoria Múltiple (FMM), Mexico's visitor permit. Cost is around $3–4 USD; often waived for same-day visits. Keep it. You'll surrender it when you leave. Lose it and the process becomes more complicated. Tuck it somewhere that is not your back pocket, not your burro, and not the bag you'll hand your four-year-old.
In the Village: What to Do
Eat at Jose Falcon's or the Boquillas Restaurant. Get the tacos. Get a margarita if warranted. It is almost certainly warranted. The village is cash-only — USD or pesos — with no ATM and no card readers. Bring more cash than you think you need; you'll want to buy things from the honor-system craft displays on the road in, and you'll want to tip your guides, your rowers, and anyone else who kept you oriented toward the correct country.
The handmade crafts — woven blankets, embroidered textiles, carved walking sticks, wire sculptures — are left out on tables and fences with a jar for payment. Nobody is watching. Nobody needs to watch. Buy something. Leave the right amount.
If you have a child dressed as a firefighter, note that you will be received warmly. Los Diablos — an elite wildfire crew of roughly 32 Boquillas residents who cross into Big Bend to fight wildfires — make emergency response a point of community pride. A four-year-old in turnout gear will be treated as a colleague.
Returning to the U.S.
Check out at the Mexican immigration office (hand back your FMM). Cross the river. At the Boquillas Port of Entry, scan your passport at the self-service kiosk. A CBP officer in El Paso will appear on a video screen to verify your entry. This is the only unstaffed legal crossing on the U.S.-Mexico border, and it works. Behave normally in front of the kiosk camera. Do not stare at your own reflection in the mirror surface. This does not convey confidence.
What you can bring back: Handicrafts ✅ | One bottle of alcohol ✅ | Food, meat, tobacco, anything made from animals ❌
Essential Tips
- Bring cash. USD or Mexican pesos. No ATMs. No exceptions.
- Check seasonal hours before you go. The border closes promptly and does not wait.
- Sunscreen and water are non-negotiable. The desert will remind you of this if you forget.
- Take the boat. It's $5 and it matters to the community.
- Learn the click. Tongue to roof of mouth, released sharply. Your burro will thank you.
- Arrive early enough to eat, walk around, and get back well before the 4 PM close.

Why This Place Matters
Boquillas del Carmen is not a tourist attraction with a gift shop and a parking structure. It is a community of roughly 150 to 200 people who built an economy around the goodwill of strangers, lost it entirely for a decade because of events 2,000 miles away, and rebuilt it when the crossing reopened in 2013. The solar farm that gave the village electricity in 2015. The school renovations. The medical office. All of it came from the reopening — from the ferry fees and the taco sales and the burro rides and the craft jars on the road.
When country music singer Robert Earl Keen showed up in the late 1980s, drank at the Park Bar, heard some guy from Texas playing guitar for tips, and went home to write "Gringo Honeymoon" — considered by many to be his finest song — he was documenting something real: a village that existed as an act of mutual good faith between two countries and two communities across a river. That still describes it today.
Go. Take the boat. Eat the tacos. Buy something from the honor table. Tip your guide, your ferryman, and anyone else who pointed you toward the right country. And if your burro stops: click.
You'll figure it out. We did — eventually. Twice. And eventually Base Camp was granted entry, taking us deep into Mexico. Read about it in: 4th Time’s the Charm: Climbing El Potrero Chico and Road-Tripping to Punta de Mita
