Amazon Forest and Amazon River

The Amazon River discharges roughly 20% of all the freshwater entering the world’s oceans from a drainage basin that covers 7 million square kilometres across nine countries. At its mouth, the river is so wide that you cannot see the opposite bank. The forest it sustains contains an estimated 390 billion individual trees of 16,000 species, roughly 10% of all species on Earth live here, and the biochemical diversity hasn’t been fully catalogued because no one has come close to finishing the inventory.

The practical challenge is that “the Amazon” is not a single destination – it’s a region the size of Western Europe, accessible from multiple countries, in different ways and at very different price points. Most tourists choose between the Brazilian Amazon (Manaus as the main hub, river cruises, and the Meeting of the Waters as the signature attraction) or the Peruvian/Ecuadorian Amazon (Iquitos in Peru, the Napo River in Ecuador, with more accessible wildlife lodges and arguably better wildlife density in the protected reserves). The choice depends on what you’re optimising for.

The Brazilian Amazon: Manaus and the Meeting of the Waters

Manaus is the largest city in the Amazon, accessible by direct flights from major Brazilian cities and internationally. The Meeting of the Waters (Encontro das Aguas) – where the black-water Rio Negro meets the tan/brown-coloured Amazon (Solimoes) and the two run side by side for 6 kilometres before finally mixing – is the most visited natural phenomenon in the region and genuinely strange to witness from a boat. The colour contrast results from temperature, speed, and chemical composition differences; the waters don’t mix immediately because they have different densities. Entry to the observation area by boat costs around 60-100 BRL per person with standard tours from Manaus.

Multi-day river cruises from Manaus are the most immersive Brazilian Amazon experience. A four-day cruise on a smaller vessel (15-30 passengers) exploring the Negro and its tributaries costs around $400-800 per person, with pink river dolphin sightings a near-certainty in the right channels.

The Peruvian Amazon: Iquitos and the Reserves

Iquitos, in northeastern Peru, is the largest city in the world with no road access – reachable only by air or river. From here, dedicated wildlife lodges in the Pacaya-Samiria National Reserve and along the Napo River provide access to flooded forest ecosystems with excellent wildlife: giant river otters, anacondas, pink and grey river dolphins, caimans, and a bird list that will take serious birders several days to work through.

Tambopata National Reserve in southern Peru (accessed from Puerto Maldonado, flying time from Lima about 90 minutes) offers clay lick sites where hundreds of macaws and parrots gather each morning, one of the more visually spectacular wildlife events in the Americas. Day visits are possible; overnight stays at dedicated lodges are far better.

What to Expect

The Amazon is not a walk in a city park. Heat and humidity are constant. Insects are significant and require serious repellent (DEET-based). Medical preparation – malaria prophylaxis, yellow fever vaccination, travel health consultation – is necessary for most areas. The rewards for accepting these conditions are encounters with wildlife and landscapes that exist nowhere else.

Guide quality is the single most important variable in any Amazon visit. A knowledgeable naturalist guide who knows where specific species shelter, how to read the forest sounds, and how to move through jungle quietly transforms the experience from background nature to specific, identified wildlife. Budget for this rather than cutting it.

The dry season (June through November in the Brazilian Amazon, June through October in Peru) offers easier navigation and better trail conditions. The wet season brings flooded forest that is beautiful and ecologically fascinating but requires boat access to areas that are dry-forest in other months.
