To travel by motorhome or trailer through the Triple Frontier, bring the vehicle document (CRLV), the Mercosur Green Card insurance, and if rented, the owner's authorization to leave the country. Always cross at customs, fill water tanks and dump sewage only at structured sites, and never spend the night at an isolated station.
Direct answer: Crossing the Triple Frontier with a camping vehicle or motorhome requires an up‑to‑date CRLV, a Green Card insurance (mandatory in Mercosur), a valid travel document and authorization if the vehicle is rented or financed. Use only official crossings (Tancredo Neves Bridge or Friendship Bridge), declare the vehicle at customs and keep receipts. Overnight only at structured sites.
Quick answer
Traveling by RV, trailer or tent through the border of Foz do Iguaçu (BR) · Puerto Iguazú (AR) · Ciudad del Este (PY) is fully feasible, but it demands preparation on three fronts: border documentation (CRLV + Green Card + authorization if the vehicle isn’t yours), infrastructure (water, sewage dump, electricity and gas are not everywhere) and security (overnight only in structured locations). This guide is the "how‑to" — the live list of campgrounds with prices and spots is on a separate page.
Documents and how to cross the border with the vehicle
Vehicle document
Bring the CRLV (Vehicle Registration and Licensing Certificate) for the current year, physical or digital, in the driver’s name or with a verifiable link. Without current licensing, customs may block the exit. Driver and passengers need a valid travel document (for Brazilians, a recent RG in good condition, CIN or passport).
Green Card insurance (Mercosur)
The Green Card is the mandatory civil liability insurance to circulate a Brazilian‑registered vehicle in Argentina, Paraguay and Uruguay. It covers third‑party damages in the visited country and is issued by your insurer before the trip, with a defined period and license plate. It is not the car’s regular insurance nor the DPVAT – it is a specific Mercosur contract. Driving without it can result in fines and seizure abroad.
Rented, financed or third‑party vehicle
Rented: you need express authorization from the rental company to leave the country; many do not allow international exit, and those that do charge a fee and issue a specific letter. Confirm before booking.

Frequently asked questions
Do I need a Green Card to enter Argentina and Paraguay with a motorhome?
Yes. The Green Card is the mandatory civil liability insurance to circulate a Brazilian‑registered vehicle in Argentina, Paraguay and Uruguay. It is issued by your insurer before the trip, with a defined plate and period, and is not to be confused with the car’s regular insurance nor DPVAT. Without it you can be fined and have the vehicle seized abroad.
Can a rented or financed motorhome cross the border?
Only with authorization. If rented, you need express permission from the rental company for international exit (many do not allow it). If financed or under a fiduciary lien, you need the bank’s authorization. If the vehicle is in another person’s name, bring the owner’s authorization with a notarized signature, ideally translated. Customs may require these documents.
Where do I dump black and gray water from the motorhome at the Triple Frontier?
Only at a campground’s sanitary point or a prepared motorhome area — which are scarce and unmarked in the region, so plan the dump around stops with facilities. Never empty on the street, in the woods, in a storm drain or riverbank: it is illegal, incurs fines and contaminates the Iguaçu basin.
Can I drive my motorhome inside Iguaçu National Park?
No, not with your own vehicle. Both on the Brazilian and Argentine sides you park at the entrance and use internal transport (bus in Brazil, train in Argentina). Confirm the parking can accommodate tall/long vehicles and do not count on overnight stays — the parks close at dusk.
What is the best time to travel by motorhome to the border?
Autumn (April–May) and spring (September–October) are the best windows: mild days, less rain and lower visitor numbers. Summer is hot, humid and crowded (Carnival and year‑end); winter has pleasant days but cold nights — bring heating. Avoid the three countries’ holidays, when the bridges jam.
Can I overnight with a motorhome at a fuel station on the border?
Not recommended. Avoid overnighting at an isolated station, shoulder or empty parking lot. Prefer campgrounds and motorhome areas with gate or guard, arrive before dark and, whenever possible, stop near other travelers. This greatly reduces risk in the region.

Financed / fiduciary lien:
authorization from the bank/finance company
Owned by another person (different name from driver): bring owner’s authorization with notarized signature, ideally translated. Customs may require it.
Crossing customs
Always cross at official posts — Tancredo Neves Bridge (BR↔AR) and Friendship Bridge (BR↔PY) — never via informal crossings. Declare the vehicle and present documents when asked. For tourism entries, the vehicle can be registered for temporary admission; keep any receipt given, as it may be requested on exit. Avoid peak hours and holidays of the three countries, when bridge queues become very long.
Best time and climate
The climate is humid subtropical, so plan for comfort inside the vehicle:
Autumn (Apr–May) and spring (Sep–Oct): the best window for motorhomes — mild days, less summer rain, parks crowded only on weekends.
Summer (Dec–Mar): intense heat and humidity (over 35 °C), heavy showers and high season crowds (Carnival, year‑end parties). Air‑conditioning and shade are essential. This is also when the Iguaçu River usually has higher flow, making the waterfalls fuller.
Winter (Jun–Aug): pleasant days but cold nights — bring heating and warm clothing; it is the driest and most stable period. July vacations fill the region.
Infrastructure for motorhome: water, sewage, electricity and gas
Potable water
Fill the tank at campgrounds and structured motorhome areas, where water is safe to drink. Stations and businesses may provide water, but confirm it is potable before filling the drinking reservoir. Travel with a full tank for long legs.
Black and gray water (dumping)
Dump points (dump stations) are scarce and unmarked in the region — don’t count on one at every stop. Dump black water (toilet) and gray water (sink/shower) only at a campground’s sanitary point or a prepared motorhome area. Never empty on the street, in the woods, in a storm drain or riverbank: it is illegal, fines apply, and it contaminates the Iguaçu basin. Plan dumps around stops with facilities and keep tank levels comfortable.
Electricity
Voltage: Argentina and Paraguay operate on 220 V; the Brazilian side has 127 V and 220 V outlets depending on the location. Bring adapters and a multimeter/tester, and verify voltage before plugging in.
Campground with outlet: most structured areas offer power; confirm amperage so you don’t trip the breaker with air‑conditioning.
Autonomy: solar panels and an auxiliary battery give leeway on stretches without power and reduce the need to stop at dubious sites just to charge.
LPG (gas)
In Brazil, refueling is done by exchanging cylinders (P13/P45) at retailers; filling a fixed tank directly at a pump is not the authorized practice. Leave the trip with a full gas cylinder.
Argentina and Paraguay use different bottles and valves than Brazil — bring adapters if you depend on gas there, or plan to cross with enough reserve.
Always close the gas valve when crossing the border and while driving.
Safety and best practices
Do not overnight at an isolated station, shoulder or empty parking lot. Prefer campgrounds and motorhome areas with gate/guard; stopping near other travelers increases safety.
Arrive at your destination before dark and drive during daylight, especially on unfamiliar stretches.
Do not leave the vehicle unlocked or with valuables in sight, especially in the busy commercial area of Ciudad del Este.
Keep copies of documents (vehicle, Green Card, authorizations) separate from the originals.
Confirm campground fees and services in advance; use official border posts and the day’s exchange rate to convert (live exchange).
What changes country to country (BR × AR × PY)
Brazil (Foz do Iguaçu): natural base of the trip — more campground infrastructure and motorhome support, 127 V/220 V outlets, gas by cylinder, Portuguese language, real. Good spot to refill water, electricity and gas before crossing.
Argentina (Puerto Iguazú): 220 V electricity, well‑established camping culture and Green Card strictly enforced. The vehicle can be registered at customs on entry; keep the receipt for exit. Some routes have tolls.
Paraguay (Ciudad del Este): 220 V electricity, fuel and gas generally cheaper, but less specific motorhome infrastructure and more urban traffic. Many travelers treat the Paraguayan side as a shopping day‑trip and return to sleep on the Brazilian or Argentine side, which is usually the smoother option.
Visiting the waterfalls with a motorhome
You do not drive your own vehicle inside the parks. In the Iguaçu National Park (Brazilian side) you leave the motorhome in the visitor‑center parking lot and take an internal bus to the trails. In the Iguazú National Park (Argentine side) the same logic applies: park at the entrance and ride the internal ecological train.
Confirm the parking area can accommodate tall/long vehicles and arrive early to secure a spot and the best lighting.
Overnight stays inside the parks are not allowed — they close at dusk. Use a campground in Foz or Puerto Iguazú as a base and make daily round‑trips (waterfalls on both sides, Itaipu, Three Borders Landmark).
Bring rain gear and protect electronics: the waterfall walkway gets wet year‑round, even on sunny days.
