Amazonia - Andes to Atlantic

Amazon river and its tributaries

By Bonnie Hamre, About.com

Amazon River

Amazonia is the geographical area surrounding the Amazon river and its tributaries. This vast area includes portions of Peru, Venezuela, Colombia, Bolivia, Suriname, French Guiana, Guyana and a huge chunk of Brazil. Orient yourself with this interactive map from Expedia.

Many travelers begin their Amazon experience either in Iquitos, Peru or in Manaus, Brazil, flying in from Lima or Rio de Janeiro or other destinations. Others begin at the "end of the line", in Belém or Macapa, where the Amazon flows into the Atlantic Ocean. Still others prefer Santarém.

Once at the embarkation point, travelers have the option of riverboats, jungle cruises, and lodges or a combination designed to see as much as possible within a few days.

Amazonia is a wonderland for botanists, birders, scientists, ecologists, tourists, anthropologists, archaeologists, gold-seekers, explorers and the curious. Sports enthusiasts enjoy whitewater rafting, kayaking, jungle walks and fishing.

Amazonia is hot and humid. Rainfall is a given. Travelers to the area must expect the inconveniences that go with heat and moisture: insects, parasites, mud, less than hygienic conditions, possible claustrophobia from being surrounded by forest, stomach disorders and other ailments. To find out if you are a good candidate for an Amazon adventure, take the Should I Go To The Amazon quiz by author Pamela Bloom.

Amazonia is:

  • "responsible for 50% of the renovated oxygen on Earth, and its hydrographic basin contains over 1000 rivers and lakes, no less than one fifth of the fresh water reserves on Earth. The Amazon is one of Nature's favourite shows, filled with the most exuberant flora and fauna known to man: thousands of noble century old trees where nearly 15,000 species of animals live; among them 1,800 bird species, 2,000 kinds of mammals and 1,500 types of fish."

  • "The largest of the world's rivers in terms of volume of water discharged into the sea is the Amazon. This mightiest of rivers forms a network of water channels that permeates nearly half the continent of South America. The main river is some 4,080 miles long, second only to the Nile in length. It is fed by more than 1,000 tributaries, including seven that are more than 1,000 miles long, and it drains more than half of Brazil, as well as parts of Bolivia, Peru, Ecuador, Colombia and Venezuela. Its total drainage basin of some 2,722,000 square miles and encompasses about one-0third of South America,an area more than 10 times the size of Texas and nearly as large as the entire contiguous United States. Over most of this vast region the climate is very warm and humid. Rain falls about 200 days each year, and total rainfall exceeds 80 inches per year. One result of so much rain is that Amazonia is covered by the largest tropical rain forest in the world. Another result is that the river carries by far the largest volume of water of any river in the world. On the average, some 28 billion gallons per minute flow into the sea, about 10 times the flow of the Mississippi. The discharge is so great that it noticeably dilutes the salinity of the Atlantic's waters for more than 100 miles offshore."

    Since the Amazon begins as tiny streams in the Andes of Peru, this is where we'll start.
