The Rio Marié is the most remote river in the Brazilian Amazon and is referred to as the River of Giants.

The Rio Marié is a very remote river—more than 400 miles by float plane from Manaus, Brazil. The Marié River is born in the northwest side of the Brazilian Amazon, near the Colombian border, and is a tributary of the upper Negro River. All of the river is contained inside an Indian territory of more than 494 million acres.
There are over 400 miles of river, tributaries, and lagoons. The Rio Marié liveaboard adventure is the first official sportfishing operation inside an Indian territory in Brazil. It is now the largest area in the world specifically dedicated to fly-fishing-only and catch-and-release only.
The speckled, the largest of all peacock bass, average 10-to 18-pounds in the more remote locations but have been known to reach 30-pounds. 2017 pending world-record peacock - almost 31-pounds! In 2016, a 28 ½-pound fly-caught peacock bass was landed at the Rio Marié. The butterfly peacock bass are abundant and smaller, reaching up to 13-pounds.
The liveaboard’s three-month seasons runs mid-September to mid-December. This is the dry season when the water levels are at their lowest. View Todd Moen's YouTube:

Rio Marié Liveaboard

Dr. Meng Syn with Rio Marié peacock bass.
The Rio Marié season runs from mid-September through mid-December. The adventure begins in the uppermost stretches of the Rio Marié with the liveaboard moving downstream at a pace of about 75 miles each week. They do not overfish any area. Anglers are greeted each day with new water, a constant and fresh trophy peacock bass fishing grounds.
Two anglers per professional English-speaking guide, plus a native guide, in specially designed fishing boats. 21-foot fully equipped shallow draft skiffs have two casting platforms (one at either end of the boat so both anglers can fish at the same time), a center console, and are powered by 90 h.p. 4-stroke motors, as well as remote-control electric motors. Most of the fishing is done using baitfish imitations.

The Untamed Amazon Mothership

Rio Marié Liveaboard

The Untamed Amazon has three floors. The lower floor is a restricted area for staff only and includes the inner workings of the vessel with twin 200-h.p. propulsion engines. The main floor has seven double occupancy suites for Rio Marié guests. Maximum number of guests is fourteen. Each suite accommodates two guests in super single beds and has a private bathroom, air conditioning, and space for storage. The top floor is the place for relaxation after a long fishing day. There is a spacious living and dining room, an open lounge on the rear deck, limited Wi-Fi, and two large Jacuzzis.
There is a full-scale kitchen which serves American meals in addition to regional favorites. You'll enjoy expertly prepared four-course dinners in the comfortable dining area. Exotic dishes of freshly caught fish, fresh baked bread and pastries, chilled wines, ice-cold beer, spirits and soft drinks await each guest throughout the week. Beer, fine wines, and spirits are included in the package.
The mobility of the Untamed Amazon – the deluxe, shallow-draft mothership – and the utilization of the Cessna Caravan fitted with amphibious floats to transport anglers direct from Manaus to the Rio Marié, is making all the difference in the world. When the water is high, they fish the headwaters of Marié further upriver, exploring new tributaries and lagoons. While there is still 100 more miles of river upstream to explore. When the water drops, they move downstream to familiar beats. Not only does this mobility allow them to fish and explore new water, but it also helps to manage fishing pressure on the river by incorporating a beat system across a broad expanse of over 200 river miles.

Getting Here:

At the international airport in Manaus, you'll be greeted by an English-speaking representative. He'll arrange for transfers to the Hotel Tropical. (The transfers and the first hotel night are included in the package.) After breakfast at the hotel, the driver will pick the group up around 7:00 a.m., and head to the local airport. From Manaus, a private four-hour charter flight, (included in the trip cost) utilizing two Cessna Caravans fitted with amphibious floats, will drop guests off on a new landing strip near the mothership. After a cold drink and lunch, anglers will have a brief orientation. You’ll get situated in your suite, and prepare tackle for a half day of fishing that afternoon.
