The Amazon is a huge place, full of rich experiences and the locals say that it would take many lifetimes to experience it all.
Marajó is an island located at the mouth of the Amazon River in Brazil. It is the largest fluvial island in the world, with a land area of 40,100 square kilometres (15,500 sq miles) and is roughly the size of the Netherlands and Switzerland. It is approximately 295 kilometres (183 mi) long and 200 kilometres (120 mi) wide.
Together with several smaller neighbouring islands, separated from Marajó by rivers, it forms the Marajó Archipelago, with an aggregate area of 49,602 square kilometres (19,151 sq mi). Large parts of the islands are flooded during the rainy season because of the higher water levels of the Amazon River along the coast and heavy rainfall in the interior. Marajó is almost entirely flat and during the rainy season, much of the island turns into a large lake.
The east side of the island is dominated by savanna vegetation. There are large fazendas (ranches) with huge herds of domesticated water buffalo on the island - c. 700,000 of them (breeds include Carabao, Jafarabadi, Murrah and Mediterranean).
Marajo island was also the site of an advanced pre-Columbian society - the Marajoara culture - which existed from approximately 400 B.C. to 1600 A.D. Washed by fresh and saltwater at one of the world's most majestic deltas, Marajó Island is an alluring destination for riding in the Amazon environment.
No more than a dozen towns are scattered on Marajó, and most of Marajó's 250,000 inhabitants live on the main island's eastern shores, where the towns of Soure and Salvaterra are located. Just like the ancient marajoara mound builders, whose culture thrived between the 5th and 14th centuries and whose survival was closely tied to the Amazon river, today's marajoara life greatly revolves around water.
To give a succinct overview of the complete fauna and flora of the Amazon is difficult. The rivers and streams of the basin teem with life, and the forest canopy resonates with the cries of birds and monkeys. There is a notable paucity of large terrestrial mammal species; indeed, many of the mammals are arboreal. Avifauna is particularly rich with about 540 species. Marajó is a birdwatcher's dream. The scarlet ibis (Eudocimus ruber), or guará is one of many species of birds which can be seen on the island - roseate spoonbills, parrots and little blue herons are some of the other birds easy to spot during the dry season (roughly May-November).
