Taimen Fishing

The largest trout on earth, in rivers nobody else is on.

From USD 8,900 per person, two rods in season. Solo on request. Everything included; the final figure is built with you.

Fly fishing for taimen on permitted rivers in the north, catch and release, from a private riverside camp or a float trip with camp moved ahead of you. Licensed guides, all permits handled, August and September only.

The taimen is the river wolf: a salmonid that grows past one and a half metres and takes a mouse pattern off the surface like a predator, not a fish. Mongolia holds the last healthy populations, on strictly permitted rivers in the north. We fish them on the fly, catch and release, from a private riverside camp or on a float trip with our own rafts, cook and guides, moving camp ahead of you each day.

The season is short and the permits are few. August and September, when the water cools and the big fish feed hard before winter, is the only window, and September is the best of it: larch turning gold along the banks, frost on the tent in the morning, a full sky at night.

Lenok and grayling fill the hours between taimen. Beginners are welcome; our guides have taught first casts to people who landed a metre of fish the same week. Rods, flies and waders are on the raft.

★★★★★ A truly unique and amazing experience

From the minute they picked up my friends and I from our hotel in Ulaanbaatar, it was clear how much thought and intention had been put into every aspect of the tour. Nyamka and CJ were wonderful tour guides. Even the different lodgings we stayed in over the three days became an interactive educational experience, first staying in traditional gers and getting to know a nomadic family, then a modern ger resort, and lastly a wonderful lodge to close out our last night.

★★★★★ Best expedition ever

We did a three week expedition that Rara Avis put together for us two couples aged 65 to 81. We stayed in lodges, gers, hotels, shared time with two different local families who took us hunting with the family's golden eagle on horseback, then went to the local eagle festival twice. If you are the adventurous, regardless of your age, take the time to truly experience Mongolia in all its beauty. I would go again in a heartbeat.

★★★★★ Best trip of my life

We did an 11 day tour from Ulaanbaatar to West Mongolia with CJ and Nyamka, and it was honestly one of the best experiences of my entire life. They tailored the entire itinerary to our group's interests, even agreeing when we wanted to skip a night at a hotel in exchange for camping. The best part of it all was the people. Everyone was so open, warm, and eager to help even when situations didn't go as planned.

★★★★★ Mongolia with Rara Avis is a must

The intentionality, professionalism, insight, and information were all 10/10. It was the perfect balance of fun, relaxation, activity, and learning. We spent one night with a local herder family, a once in a lifetime experience, as well as a night in a very comfortable lodge and another in a classic ger hotel.

★★★★★ Wonderful time exploring Terelj Park

The tour company was on time and the guide and driver were professional and helpful. The horseback ride through the green woods above the temple and around Turtle Rock was great. We changed the riding pace and I felt safe the entire time. Lunch at their gorgeous lodge was great.

★★★★★ Unforgettable three day Mongolian adventure

At Hustai National Park we were incredibly lucky to see Mongolian wild horses up close, less than 100 metres from our car. Our guide explained everything, from nomadic life to Buddhism and the Mongol Empire, in a way that was both accessible and insightful. Special thanks also to our driver, whose superb driving skills made us feel safe and comfortable at all times.
