Overland Trip With Kids: How to Plan as a Family
How to plan an overland trip with kids through South America: documents, vehicle safety, daily routine, education on the road and children's health.

The question that comes up regularly in every Brazilian overlander group: "can you make this trip with a child?" The short answer is yes, and in many cases, with a child the trip is even better, not worse. The long answer requires recognizing that the logistics change, the pace changes, and some decisions need to be reassessed. Those who ignore these changes and try to do an "adult trip with a child tagging along" suffer. Those who adjust the trip to family reality discover one of the richest experiences the road has to offer.
This article is for anyone considering taking a child on an overland trip, whether a short two-week trip across the border or a long route of months through South America. It applies to a family with a child of any age, with adjustments for each age group.
In short: an overland trip with a child requires adjustments on four fronts: paperwork (minor's authorization for the border, their own passport, pediatric vaccines up to date), vehicle (an appropriate car seat, shade, space to play at stops), routine (reduced mileage, frequent stops, mealtimes and naps respected), and informal education (the road becomes a classroom). The trip gets slower, and almost always the traded pace is worth it.
Is it worth taking a child?
Before the logistics, the honest question.
It is especially worth it when:
- The child already travels well by car (short distances without constant meltdowns).
- The couple or guardians have patience for a slower pace.
- The itinerary is flexible enough to adapt when needed.
- The child is old enough to form a memory of the trip (from 4 or 5 years old, memories begin to stick).
Think again when:
- A very small baby (under 6 months) on a long international trip: a big physical challenge, little enjoyment of the scenery.
- An itinerary with extreme altitude (above 4,000 m): children suffer more than adults from lack of oxygen.
- A child with an ongoing medical need that requires a nearby hospital.
- A trip with many days in a row on a deserted route with no mid-size town.
Older babies (6 to 18 months) usually travel well: they sleep a lot in the car and adapt quickly. Preschoolers (2 to 4 years old) are the age group that tires you out most because they demand constant attention. Over 5, children start to participate actively: asking questions, observing, helping plan. A teenager makes the trip almost an adult trip.
Specific paperwork
A child adds layers of paperwork on top of everything already required for adults, on top of the checklist of documents to cross borders.
Minor's travel authorization
A document that authorizes the child to travel without one parent, or without both, as the case may be. For international travel, it is mandatory at almost every South American border.
- With both parents together in the vehicle: a proof of parentage (birth certificate) is enough.
- With only one parent: authorization from the absent father or mother with a notarized signature.
- With neither parent (child with a grandparent, uncle, or guardian): authorization from both parents, with notarized signatures and, in some countries, a sworn translation.
Note: some borders require the authorization to have been issued less than 60 or 90 days ago. Get it close to the trip.
Passport
Every Brazilian child needs their own passport to travel internationally. It is not enough to be listed on a parent's passport, that model no longer exists. A child's passport is valid for a shorter time than an adult's (5 years for children up to 12), so check before going.
Pediatric vaccines
Basic schedule up to date (BCG, hepatitis, pentavalent, MMR). Specific travel vaccines (yellow fever over 9 months, hepatitis A second dose) according to age. The pediatrician will guide you. Book an appointment 45 days ahead.
Medical prescription
If the child takes continuous medication, bring a legible prescription in Portuguese, and a Spanish translation if possible. It makes it easier to buy at a local pharmacy if you run out.
Vehicle and safety
The base rule does not change: a car seat appropriate for age and weight, properly secured, on every stretch driven. But some specific decisions weigh more on a long trip:
- Car seat for a long trip: a model with good ergonomics, reclining (the child will sleep a lot in the car), with side protection. A city-use model can get uncomfortable after 4 to 5 hours.
- Shade: the sun is strong on altiplano roads, in the desert, and in Patagonia in summer. Window tint on the side glass (if allowed by local law) or interior curtains. In a motorhome or converted van, it is easier to solve.
- Space to play at stops: the car is the "trip bedroom." For a child, sitting 6 hours in the seat and stopping 20 minutes to stretch does not work. Stops need to be longer and in a place where they can run (a big gas station, a plaza, a park, a safe lookout).
- Always-accessible items: water, snacks, diapers (if applicable), wet wipes, a trash bag, an on-board book or toy, a change of clothes.
- Front or back seat: for safety, the child always rides in the back. On a long trip, it is worth alternating who drives and who sits in the back with the child. Whoever is in the back can entertain, distract, and meet needs without making a stop.
The daily routine changes, and that is fine
Here lives the most important adjustment. Mileage drops by half or more. What an adult alone does in 8 hours, a family with a child does in 12, because the routine includes:
- Stops every 1.5 to 2 hours (bathroom, stretching, eating fruit).
- A sit-down lunch, not eating in the car, or a relaxed meal at a picnic-table stop.
- The child's nap. Fit the most tiring stretch of road into that time.
- Arriving early at the destination: a child eating dinner at 6 p.m. and sleeping at 8 p.m. means the last stretch of the day should end before 5 p.m.
What pace works in practice:
- Adult alone or couple: 500 to 700 km per day comfortably.
- Couple with a small child (up to 6 years old): 300 to 400 km per day.
- Family with a school-age child: 400 to 500 km per day.
The consequence is that itineraries need to be rethought in duration. A trip an adult makes in 20 days, a family makes in 30. Those who accept this adjustment have a good trip. Those who try to force the adult pace turn it into a car marathon with a daily family crisis.

Education on the road
A long trip requires a decision about school. Three common paths:
- Short trip within the school term (up to 2 weeks): arrange complementary activities with the school, such as a travel journal, photos, and a short presentation on return. Most schools accept an excused absence in this format.
- Medium trip (1 to 3 months) during the school term: informal homeschooling keeps the child on track with reading, math, and writing. It does not replace formal school, but avoids a total loss. School material sent as PDFs, exercises done in a regular notebook, daily reading. Some schools allow a temporary suspension.
- Long trip (6 months or more) or open-ended: consider formalized homeschooling or worldschooling. In Brazil, it is still a legally complex topic. Alternative: enroll the child at the start or end of the school year, travel during the extended vacation period, or use structured digital content.
Regardless of the format, the trip's informal education delivers:
- Real geography: a physical map, identifying terrain, vegetation, climate.
- Language: Spanish in daily life, interaction with locals.
- History and culture: pre-Columbian sites, museums, contact with native peoples.
- Biology: wildlife in parks, vegetation in different biomes.
- Coexistence and adaptability: social skills, patience, problem solving.
More education per month of travel than a year of classroom on several topics.
Child-specific health
Visit the pediatrician 45 days before the trip, to check that vaccines are up to date, prescribe altitude medication if applicable, and certify general health. The vaccines and health checklist for overland travel covers the adult side of the same preparation.
Pediatric vaccines for travel: yellow fever over 9 months (mandatory for Bolivia, Peru, Colombia), hepatitis A second dose, MMR up to date, COVID according to the current protocol.
The medical kit carries everything in the adult kit, plus:
- Digital thermometer for children
- Pediatric pain reliever and fever reducer (acetaminophen or ibuprofen, as advised)
- Oral rehydration salts in sachets
- Children's bandages (ones with cartoon prints help with acceptance)
- Repellent formulated for children (do not use adult repellent on a small child)
- Pediatric sunscreen SPF 50+
Altitude: children suffer altitude sickness faster and harder than adults. Climb very gradually. Above 3,500 m, pay extra attention to a heavy head, vomiting, and loss of appetite. A strong symptom means going down.
Traveler's diarrhea: common in children changing water and food. Intense hydration, oral rehydration salts, light food. In a severe case, see a doctor. Dehydration in children is serious.
When it is not worth the risk
Honesty that many people avoid voicing:
- Baby under 4 months: a long trip is very costly, with little enjoyment for everyone.
- A stretch above 4,000 m for many days in a row: a real risk for a child. The Bolivian southwest with a small child requires careful evaluation.
- A route with a lot of severe ripio: extreme discomfort for a child who gets carsick. The interior of the Carretera Austral gets uncomfortable.
- An itinerary with few mid-size towns: a pediatric emergency on a deserted route is a difficult scenario.
- A family going through a hard time (divorce, grief, crisis): a long trip amplifies, it does not dilute.
None of these is "forbidden." Some travel anyway and it works out. But recognizing the challenge before leaving reduces frustration later.
Frequently asked questions
From what age is it worth taking a child on a long overland trip?
From 6 months on, the trip becomes viable. Between 3 and 6 years old is the most tiring age group. Over 5 or 6, the child participates actively. The choice is not "what is the ideal age," it is "how do I adapt the trip to the age I have."
Can I do official homeschooling during the trip?
In Brazil, homeschooling regulation is still being built. The most common path: arrange with the school an enrollment model with excused absence or temporary suspension. On a long international trip, some states accept the child taking assessments on return.
How do I prevent carsickness in a child?
A well-positioned car seat (high enough to see the scenery), ventilate the space, avoid a heavy meal before hitting the road, stop early at the first symptoms. Pediatric dimenhydrinate only with medical guidance.
Is it worth doing an overland trip as a single-parent family?
It is, with extra adjustments. Paperwork gets simpler, with no need for authorization from the other parent, but daily logistics are heavier because everything falls on one adult. A shorter itinerary, longer stops, and extra attention to your own rest help.
What if a medical emergency happens on the route?
A mid-size town in any South American country has a public hospital. For children, emergency care is practically universal and generally free or very cheap. International health insurance with pediatric coverage is prudent. Some plans have specific coverage for minors.
Wrapping up
An overland trip with a child is not a "harder" version of an adult trip, it is a different trip. Slower, more detail-oriented, with stops that adults alone would not make, with questions that change the way you look at what is around you. The child turns the traveler into someone more patient, more observant, more present. And what the child takes from the trip, the geography learned by driving, the language truly heard, the sense that the world is big and varied, cannot be reproduced in a classroom. The logistics weigh at the start. The following years show it was worth every kilometer.
