The Rio Negro presents an otherworldly landscape: mirror-like black waters reflect the rainforest’s emerald canopy, creating a realm of mystery and unparalleled biodiversity. Here, the Amazon’s secrets seem to whisper on the current. To truly understand this hidden world, you need a guide, someone who speaks the river’s language. Enter Jordi Miguel, a seasoned naturalist and ichthyology expert, whose life is interwoven with the Amazon’s rhythms. Jordi’s passion translates into unique Amazon River cruise experiences, journeys that delve beyond the surface, revealing the intricate life thriving beneath the dark waters and within the surrounding rainforest. The sensory immersion is incredible. The sounds of the rainforest, the unique scent of the flora, and the feeling of the dark water against the hull is something that is hard to describe.
In the summer of 2022, River Mixer traveled to Manaus to collect the Amazon River and Rio Negro, and to learn more about the region’s river systems. We embarked on Jordi’s popular 5-day exploration of the Anavilhanas Archipelago, the very itinerary we are about to describe. A last-minute cancellation left us with the entire boat to ourselves for a few nights, allowing for one-on-one experiences with Jordi and his crew, a truly unforgettable excursion. The cook even expertly filleted the piranha we caught the day before, for a unique lunch experience. Let us share with you, the unique experience of the Rio Negro, as seen through the eyes of Jordi Miguel.
Since 2002, Jordi has dedicated himself to exploring and understanding the Amazon, with a deep specialization in the aquatic ecosystems of the region. His years of experience have made him an invaluable resource for biologists, photographers, and adventurers alike. His specialization in ichthyology (the study of fish) is key. The Amazon teems with diverse aquatic life, and Jordi’s knowledge allows him to pinpoint and explain the fascinating adaptations of these creatures. He often shares stories of discovering rare fish species or witnessing unique aquatic behaviors. He has tales of the Arapaima (Pirarucu), and many other amazing fish. He knows the best places and times to look for specific species. His vessels “Lo Peix” and “Acqua Amazon” are more than just boats, they are mobile research stations, and gateways to the hidden Amazon world, with a strong emphasis on the Rio Negro’s unique environment. His passion for the river is infectious.
The Rio Negro’s dark, acidic waters are a result of decaying vegetation, creating a unique environment distinct from the sediment-rich ‘white water’ of the main Amazon. This acidity is a vital factor in the biodiversity of the river. Despite its dark appearance, the Rio Negro is a haven for an incredible variety of life. From colorful cichlids to elusive river dolphins, the ecosystem is teeming with wonders. Unique flora, like the flooded forests (igapós), and fauna, such as monkeys, sloths, and a vast array of birdlife, as well as unique fish, thrive here. The lack of mosquitos due to the water acidity, and the differences in pH, water clarity, and fish types, when comparing the Rio Negro to the main Amazon river, are very important factors to understand. The “Meeting of the Waters” is a spectacular sight, where the dark waters of the Rio Negro and the muddy waters of the Solimões River (the name often given to upper stretches of the Amazon River ) run side by side for miles, due to differences in water chemistry, temperature, and speed. It’s a natural wonder that must be seen to be believed.
Jordi’s presence transforms a typical river cruise into an immersive educational experience. He doesn’t just point out wildlife; he explains the intricate relationships within the ecosystem. Activities like piranha fishing, nocturnal wildlife spotting, exploring flooded forests by canoe, and guided nature walks offer educational experiences. Opportunities to see rare and elusive wildlife, such as pink river dolphins, monkeys, and a plethora of bird species, are available. Nature enthusiasts, wildlife photographers, and anyone seeking an authentic Amazon experience, would most enjoy these expeditions. These small group tours, allow for an intimate experience, and access to areas larger boats cannot reach.
Jordi and his team offer a popular 5-day cruise up the Rio Negro, exploring the Anavilhanas Archipelago. This journey includes:

Our journey into the heart of the Rio Negro, guided by Jordi’s deep understanding, underscored the vital importance of preserving this unique ecosystem. The Amazon, with its intricate web of life, is a treasure that demands our respect and protection. As we add these river samples to our collection, let us remember that every drop of water, every creature, and every moment spent in this extraordinary place reminds us of our shared responsibility to safeguard these invaluable natural wonders for generations to come. By supporting eco-conscious explorations like those offered by Jordi Miguel, we can contribute to a future where the Rio Negro, and the Amazon as a whole, continue to thrive.
The Rio Negro’s dark, acidic waters are a result of decaying vegetation, which releases tannins and other organic compounds into the river.
The “Meeting of the Waters” is where the dark waters of the Rio Negro and the muddy waters of the Solimões River converge, creating a striking visual contrast as they run side by side.
Activities include piranha fishing, nocturnal wildlife spotting, canoe trips through flooded forests, guided nature walks, visits to local communities, and opportunities for swimming and beach visits (seasonal).
The Anavilhanas Archipelago is a vast network of islands and flooded forests in the Rio Negro, known for its exceptional biodiversity and scenic beauty.
You can expect to see pink river dolphins, various monkey species, sloths, numerous bird species, diverse fish (including piranhas and Arapaima), and potentially caimans and other reptiles.
