About the Amazon
The Amazon River and basin
The Amazon River has a length of approximately 6,800 kilometers and flows
through the biggest rainforest in the world, the Amazon, and through three
countries. Downstream the river becomes navigable in Iquitos (Peru), just after
the confluence of the Ucayali and Marañón rivers where it takes its name. From Leticia upstream the
river flows 116 kilometers through Colombia between the Atacuari River and the San
Antonio Creek. The river is called the Amazon, except
between Tabatinga and Manaus (both Brazil), where it is called Solimões.

The Amazon basin covers nine countries and measures approximately 7 million square kilometers.
It holds 20% of the fresh water of the world and is home to 30% of all living animals and plants of the planet.
It contributes, through its more than 300 kilometers wide mouth, with more than 200,000 m3/sec of fresh water to the sea
and its fresh waters may be found 200 kilometers offshore.
The Triple Frontier Zone or Amazonian Trapezium
The term ‘Amazonian Trapezium’, which originally applied to the shape of the Colombian frontier with Peru and Brazil over the Amazon River,
is today used more widely to refer to the area of 200 kilometers of tourist trails along the Amazon and Javari Rivers which
encompasses places of great interest and natural beauty.
Leticia is a Colombian town at the river side and its Brazilian neighbour town Tabatinga
is separated from it by the frontier line.
The Peruvian village of Santa Rosa is situated opposite to Leticia and Tabatinga, across the river, on the southern bank.
Leticia is a quiet town with an airport, a river harbour, a hospital, several clinics, banks,
money exchange facilities, cash machines, post offices, and internet cafés.
Leticia is connected with the national and international mobile telephone networks.
Medical services such as Sanitas may also be found.
Puerto Nariño is a Colombian town at the Loretoyacu riverside, 85 kilometers away from Leticia.
This river is a tributary of the Amazon River.
Puerto Nariño is known as "The Nativity Scene of the Amazon" and is acknowledged for its ecolological approach; any form of petrol
propelled vehicle is forbidden in town and they pride themselves on their rubbish disposal. There is a hospital,
an internet café and is connected to the mobile network both local and long distances.
The Brazilian towns of Tabatinga, Benjamin Constant and Atalaia do Norte also provide the visitor with sufficient infrastructure for a pleasant visit.
The Amazonian Trapezium is a safe place.
The fauna of the zone is not as dangerous as it is otherwise generally believed: piranhas prefer fruit and cold meat;
the most lethal snake of the subcontinent can not be found in the area and the numbers of mosquitoes are not greater than
anywhere else in the tropics.
