Pirarucú Lodge is one of the most unique and specialized fly fishing destinations in the world, offering anglers the rare opportunity to target arapaima—one of the largest freshwater fish on Earth—on the fly. Located deep within Brazil’s Mamirauá Sustainable Development Reserve, the lodge sits in the largest protected arapaima sanctuary on the planet, a vast network of lakes, lagoons, and flooded forest between the Solimões and Japurá Rivers. This fishery is defined by its exclusivity and conservation model. Pirarucú is the first and only government-approved fly fishing operation focused on arapaima, developed in partnership with local indigenous communities to protect the species while creating sustainable economic opportunities. The result is a carefully managed program with limited angling pressure and a thriving population of fish that can reach sizes exceeding 200 pounds.
The setting is quintessential Amazon—flooded forests, still backwater lagoons, and an overwhelming sense of immersion in one of the most biodiverse ecosystems on Earth. Unlike river-based fisheries, Pirarucú focuses on stillwater environments where arapaima surface regularly to breathe, giving anglers visual cues and shot opportunities unlike anywhere else in the world. While arapaima are the primary draw, the fishery also offers a surprising diversity of species. Arowana provide acrobatic surface eats, tambaqui offer technical, permit-like challenges, and additional species such as peacock bass and piranha round out the experience.
The lodge itself operates with a strong emphasis on sustainability, community involvement, and low-impact tourism. With limited weekly capacity, guests enjoy an intimate and highly personalized experience, with access to vast, untouched waters that feel entirely their own. For anglers seeking a true “bucket list” experience—one centered on giant fish, visual presentations, and meaningful conservation—Pirarucú Lodge stands alone as one of the most compelling freshwater destinations in the world.

Fishing at Pirarucú Lodge is unlike any traditional fly fishing experience. The primary focus is targeting arapaima — massive, air-breathing fish that surface regularly, allowing anglers to visually locate and present flies with precision. These encounters are deliberate and technical, often requiring patience, timing, and accurate casting to intercept fish as they roll in shallow lagoons. Anglers fish primarily from custom-designed skiffs equipped with casting platforms and electric trolling motors, allowing for quiet, controlled approaches in still water environments. Each boat is staffed by both a professional English-speaking guide and a local indigenous guide, combining technical expertise with deep knowledge of the fishery. Hooking an arapaima is only the beginning — these fish are known for explosive power, long runs, and dramatic surface thrashing. Fish exceeding 100 pounds are common, and larger specimens are encountered each season, making this a true big-game freshwater experience.
Beyond arapaima, anglers can target arowana on floating flies, tambaqui with fruit imitations, and a mix of additional Amazon species. This diversity adds variety throughout the week and offers technical challenges beyond sheer size. Each day is dynamic, with guides rotating through different lakes and channels based on water levels and fish activity, ensuring fresh opportunities and a constantly evolving fishing experience.
Accommodations at Pirarucú Lodge are centered around the Uakari Floating Lodge, a comfortable and authentic Amazon structure built in traditional caboclo style. The lodge floats within the reserve, connected by wooden walkways that link private cabins to a central dining and social area.
There are ten en-suite cabins, each designed to provide comfort while maintaining a strong connection to the surrounding environment. Rooms feature private bathrooms, natural ventilation, and simple, functional furnishings suited to the tropical climate. The main lodge includes a dining room, lounge, and bar area where guests gather for meals and relaxation. Despite the remote location, amenities include daily laundry service, Wi-Fi, and a satellite phone, providing a level of comfort uncommon in such a wild setting.


Meals are a highlight, featuring fresh, locally inspired cuisine and Brazilian specialties. The atmosphere is relaxed and communal, with a focus on storytelling and shared experiences after a day on the water.
Weekly Capacity: ~8 anglers Guest Ratio: 2 anglers per boat (1 pro guide + 1 native guide)
Pirarucú Lodge offers a rich experience beyond fishing, making it an excellent destination for non-angling companions. Located within the Mamirauá Reserve, the lodge provides access to one of the most biodiverse ecosystems on Earth, with abundant wildlife and unique cultural experiences. Guests can participate in guided wildlife excursions, exploring the flooded forest and observing monkeys, birds, reptiles, and other native species. Birdwatching is particularly exceptional, with countless species inhabiting the region’s waterways and canopy. Ecotourism activities are integrated into the program, often led by local guides who share knowledge of the environment and indigenous traditions. Boat tours through the reserve offer a peaceful way to experience the Amazon, while the lodge itself provides a relaxing environment to unwind, read, or simply take in the surroundings. The combination of wildlife, culture, and untouched nature ensures that non-anglers have a meaningful and immersive experience alongside fishing guests.

PIRARUCU HIGH WATER POLICY
Fishing in the Amazon jungle represents one of the last frontiers in the fly fishing world. As with any such hyper-remote destinations, there can be challenges associated with offering a first-class experience in the ‘back of beyond’ . In the Amazon, water level conditions will, on occasion, present such challenges. The Amazon River annual water level cycles are not a simple equation, even for the most experienced local experts. Normally, high and low water levels here follow a fairly predictable monthly cycle, but climate changes and the effects of stronger or weaker El Niño and La Niña cycles can directly and immediately affect those levels.
Specifically, these El Niño and La Niña events tend to impact the amount of rain in the headwaters of Amazon rivers, which in turn affects the entire Amazon basin.
Water levels are important when fishing for peacock bass, and understanding how to work around them is a key component to success. Low water does not always result in the best fishing, just as high water is not always the worst thing. More important is to understand where and how to fish as the water fluctuates. Though the Pirarucú season has been chosen to coincide with the best water conditions annually, it’s difficult to predict water levels, and this is one of the risks associated with fishing the Amazon.
If you are not comfortable with the risk of the river levels being too high or low during your trip, then it is probably not the trip for you. You will not be refunded for water conditions that may not meet your expectations. In the event the water is too high to fish on any given week, Pirarucú will re-schedule your week to a later time, but will not refund your trip payment.
Given the strict cancellation and refund policies associated with nearly all fishing packages, we cannot stress enough the importance of obtaining travel insurance to protect your investment.

Travel to Pirarucú Lodge is notably efficient for a remote Amazon destination. International travelers typically arrive in Manaus, Brazil, the primary gateway to the Amazon. From Manaus, a short commercial flight — approximately 50 minutes — takes guests to the town of Tefé. Upon arrival in Tefé, guests transfer by boat for roughly one hour into the Mamirauá Reserve, arriving directly at the floating lodge. This streamlined access makes Pirarucú one of the easiest jungle lodges to reach, especially compared to more remote fly-in destinations.
The relatively short travel time allows for flexible trip lengths, typically ranging from 2 to 7 nights, and also makes it an excellent option to combine with other Amazon fisheries. Despite the ease of access, the experience remains fully remote — once inside the reserve, guests are immersed in pristine wilderness with no outside pressure or development.
Pirarucu operates from early September to the end of November.
The dry season in this part of the Amazon runs from July through January, so this season straddles the middle of the dry season when water should be low and fish congregating in the lakes and channels. Rainy season in the southeastern Amazon begins in late November/early December and the rivers reach their highest levels in March. After the rainy season ends, water clarity improves and river levels start to drop. Millions of fish begin their migration upstream to find food (trophics migration) in the most oxygenated waters on granite base, riffles and rapids. Predatory fish follow this migration and the pulse of life comes back to the headwater system. The dry season is characterized by hot and breezy days, cool nights and very few mosquitoes and blackflies. This is a pleasant time of year that the Kayapó refer to simply as “nice”. In contrast, the rainy season is characterized by torrential rain, the inundation of rivers and creeks and annoying clouds of biting insects.
