Lo Peix: 7-Day Cruise

7-Day Expedition to the Heart of the Amazon (Jau National Park)

This 7-day charter-only cruise transports adventurous groups to the wild, little-explored Jau National Park, one of the most uninhabited places on Earth, a unique world hosting peculiar and unique ecosystems.

Discover a lost city and ancient caves, and explore the wonders of the incredible maze-like Anavilhanas archipelago with over 350 islands, home to manatees, pink dolphins and piranhas.


Please note that the itinerary below is dependent on the river water level, weather conditions, wildlife behavior, and accessibility to locations, so may vary. All times indicated are approximate, and are also subject to change.

In the dry season (Sep-Mar typically) a spectacular 9-tier waterfall on the Carabinani River is visible, however charters in extreme drought (Nov - Jan typically) are not recommended due to inaccessibility.

Day 1
Manaus - Meeting of the Waters - Lake Januari 

Depart from Marina David (near the Hotel Tropical) at 10:00 hrs.

After being welcomed onboard Lo Peix by the crew and having made yourself at home in the cabins, a brief meeting will be held to go over the boat's facilities and to inform you of what awaits over the coming days.

As we start cruising on the planet's mightiest river system, we will see the main attractions on the edge of the city of Manaus: The miraculous feat of engineering of the floating port, the favelas (typical houses on stilts), and beautiful market. Eventually we will reach the natural phenomenon of the Meeting of the Waters.

We continue sailing on the River Negro and head towards the ecological reserve of Lake Januari where we see typical houseboats and take a canoe ride through the flooded forest 'Lagunas de Varcea'.

Witness the abundant and varied flora and fauna  of these muddy waters, including several bird species and plants including the Amazon's giant water lily (Victoria regia) and giant Samaúma trees.

In the evening we continue sailing to the lake in the Arara Ecological Reserve Palmeral, the gateway to the Anavilhanas Archipelago National Park.

Day 2
Anavilhanas Archipelago National Park 

We spend the second day exploring the remarkable archipelago, beginning with a jungle trek accompanied by a local guide on which we will be wildlife spotting and learn some of the jungle's mysteries and secrets. Not only that but we'll have a class in jungle survival and learn how to identify medicinal plants used for centuries by local tribes, and the techniques of hunting by blowgun and bow.

Later we visit a small village of Tatuyo Indians, one of the 26 ethnic groups that have originated along the banks of the Negro River. Here we can learn how these Indians live on their plantations, hunting, fishing, making manioc flour and they tell us some of their stories and legends.

Navigating this uninhabited archipelago, consisting of over 350 islands, we have the opportunity to tour this river paradise where crocodiles, iguanas, parrots, monkeys, dolphins and manatees can be found.

At night we head out by canoe to see and hear the animals that live in the surrounding lakes, including large caimans!

Overnight we sail inside the archipelago towards the Madada caves.

Day 3
Madada Caves - Anavilhanas 

At dawn we head out by small motorized canoe into the Anavilhanas Archipelago, a quiet place away from the normal navigation routes where we can enjoy great bird watching, with parrots, macaws and ospreys common.

Later we walk about two hours through the jungle to reach the Indian Madada caves, a place little known in the middle of the jungle, only reachable by boat, canoe and hike and with the help of those in the know! The caves are a magical, unique place where the tribal chiefs of the Waimiri Indians once hid during the Portuguese occupation.

In the afternoon we navigate the Anavilhanas Archipelago towards the indiginous reserve of the Waimiri-Atroari where we'll take a night canoe ride around the islands for wildlife watching and listening to the nocturnal sounds of the jungle.

Canoeing on muddy waters

Day 4
Velho Airão

Today we embark on a quest to find the lost city of Velho Airão, an old and prosperous city, now abandoned after the rubber boom and engulfed by lush rainforest.

Here at the gateway to the Jau National Park, we can deepen our understanding about the rubber boom era, as the city, one of the era's final reminders, tell us her dark history of wealthy families that controlled the rubber trade.

Day 5
Jau National Park 

The Jau National Park is the largest national park in Brazil, a continuous tropical rainforest located between the municipalities of Novo Airão and Barcelos. Currently, this ecological paradise is known as a model of Conservation Unit in Amazonas and together with the Sustainable Development Reserves of Amana and Mamirauá, is the largest biological corridor preserved in Brazil and one of the largest in the world, at more than 5.7 million hectares in size.

Here the human presence is minimal and the permitted activities are restricted to sustenance and survival. Here, as we explore by canoe, we are more likely to observe some types of animals such as capybara, tapir, paca, large caiman, herons, otters and jaguars.

In the afternoon we navigate the Jau River, taking time for an afternoon stroll. Depending on water levels we may also navigate all the way to the Carabinani River to witness a spectacular 9-tier waterfall.

At night we again head out by motorized canoe for another opportunity to observe the abundant wildlife of the park.

Day 6
Jau National Park  

Today we wake up early to venture on a canoe ride in time to catch the early birds and other wildlife as we watch the sunrise, arguably as spectacular as the famous Amazon sunsets.

In the shadow of the sacred, giant Samaúma trees we head out on a jungle trek to explore the terrestrial wonders of the rainforest, and (depending on water levels) to reach a small  and refreshing waterfall.

In the afternoon we begin navigating the Jau River and Anavilhanas Archipelago back towards Manaus.

Day 7
Ariau River - Acajatuba Lake - Manaus 

This morning we will reach and explore the Ariau River where the famous Amazon film Anakonda was filmed so you'll be glad to hear you'll be taking a small motorized canoe ride down the river! The lakes here are influenced by the waters of the Amazon River, promoting rich flora and fauna different from that seen so far on the expedition. It is common to spot different species of monkeys, ospreys, kingfishers and other small, colorful bird species.

From that activity onward it's all about getting wet! Firstly the chance to swim with the inquisitive and perpetually smiling Pink River Dolphins that grace the Amazon (optional) at Acajatuba Lake.

Then you can take a swim in the dark waters at one of the white sandy beaches that form in the Negro River before your journey back to Manaus.

Disembark at Marina David between 13:00 and 14:00 hrs.

  • Please note that all cruise itineraries are subject to change due to seasonal weather conditions (and resultant variations in river and tributary water levels) affecting accessibility to locations. Thus navigation routes, times and excursions may need to be modified at the cruise captain’s discretion.
  • Passengers should also be aware that animal sightings cannot be guaranteed due to the unpredictability of wildlife behavior.
