The Fishing

Anglers fish new water every day, floating downstream in ClackaCraft drift boats between a series of comfortable riverside camps -- two guests and one guide per boat, with guides rotating so you fish with a variety of experienced hands over the trip.

When you reach each evening's camp, staff have your bags waiting, beds made, fires lit and dinner prepared. Accommodation on the river is in spacious gers and tent-tipis, two anglers per tent.

Getting There

Mongolia is reached via non-stop flights into Ulaanbaatar (UBN) from Seoul, Beijing, Frankfurt, Hong Kong, Istanbul or Tokyo -- most guests connect via Seoul (3+ hours to Mongolia) or Istanbul (8+ hours). Most nationalities, including Australians, do not currently require a visa.

After an overnight in Ulaanbaatar, it's a scenic 4WD journey across the Mongolian steppe to reach the river, or an optional 60-90 minute charter flight direct to a landing zone near camp.

Conservation

This river was the first in Mongolia to legally require catch-and-release, single-barbless-hook, fly-fishing-only for international anglers, and operates as a designated Taimen Sanctuary. Camps are temporary with no permanent infrastructure, cement or glass, and guests are moved between camps by non-motorized raft or drift boat once on the water.
