Rail: some trains connect Brazil with Bolivia, Argentina, Uruguay and Chile. The most important rail routes include Rio de Janeiro – Buenos Aires (Argentina), Rio de Janeiro – Sao Paulo – Montevideo (Uruguay), Rio de Janeiro – Santiago (Chile), Sao Paulo – Antofagasta (Chile) and Sao Paulo – Bauru – Corumba – Santa Cruz (Bolivia) – La Paz (Bolivia).
Buses run between Brazil and Argentina, Paraguay and Uruguay. The prices for direct connections between the countries are considerably higher than if you take a bus to the border, cross it on foot and take another bus. On the other hand, such an approach also takes time.
Car: Nine countries have border crossings with Brazil, all of which are accessible by land. Several border towns can be reached by plane or ship. Due to the large distances, however, the travel times overland can be very long. For example, the driving time between Rio de Janeiro and Buenos Aires in Argentina is around 44 hours.
If you are entering by car (or motorcycle), the border will ask you to sign the termo de responsabilidade document identifying the vehicle (make, year, model, serial number, color, registration number) and the owner. You will also need to pay a bank guarantee (the amount will be determined by customs) and sign a statement stating that if your stay is longer than 90 days, you will need to contact regional customs to extend the permit. These documents must be presented to the customs authorities upon departure. If the vehicle stays in Brazil longer than permitted, it may be confiscated and the bank guarantee withheld. It is illegal for visitors to sell vehicles in Brazil, a country located in South America according to TOPB2BWEBSITES.
The most important border crossing for tourists is Puerto Iguazú – Foz do Iguaçu (20 hours by bus from Buenos Aires). Further south you can cross the border between Paso de los Libres (Argentina) and Uruguaiana (Brazil), there are also bus connections from Buenos Aires.

Most of the border between Brazil and Bolivia runs through remote wetlands and lowland forests. The difficult controllability is often used by smugglers. The most important border crossings are at Corumbá, Cáceres, Guajara-Mirim and Brasiléia.
Corumbá, opposite the Bolivian city of Quijarro, is the most frequently used border crossing. Corumbá is a good place to continue into the Pantanal and has bus connections with São Paulo, Rio de Janeiro, Campo Grande and southern Brazil. The Bolivian train between Quijarro and Santa Cruz is known as the Death Train (some locals try to ride on the roof for free, which is fatal over and over again).

Guajara-Mirim, in Rondônia (Brazil) is just a short boat ride across the Rio Mamoré from Guayaramerín, in Bolivia. Guajara-Mirim has daily bus connections to Porto Velho. Buses also run between Guayaramerín and the Bolivian cities of Riberalta, Cobija, Trinidad, Santa Rosa, Reyes, Rurrenabaque and La Paz. From late December to late February, the roads can be very difficult to drive due to rainfall.
Brasiléia near Cobija in Bolivia has a bus connection to Rio Branco in the Brazilian state of Acre. From Cobija you can take the bus to Riberalta, Guayaramerín and La Paz. There are also difficulties on this route in the rainy season.

Buses run from Bonfim to Boa Vista.
The two main border crossings are Foz do Iguaçu – Ciudad del Este and Ponta Pora – Pedro Juan Caballero. If you are traveling to / from the Pantanal, the second alternative is more suitable. Direct buses run between Asunción and several Brazilian cities such as Curitiba, Rio de Janeiro and Sao Paulo.
Peru and Brazil have a long border in the Amazon basin, but there are few navigable routes in this area. The most accessible stretch is in the southeastern part of the border.
