Top 10 Fishing Spots in Mongolia
Mongolia sits at the top of the world's salmonid map, a land of vast grasslands, permanent rivers, and glacially cold mountain streams that hold species few anglers outside the region have ever encountered. The taimen, known locally as sg and reaching lengths exceeding 1.5 metres and weights of 80 kg in exceptional fish, is the primary draw — a river tiger that surface-strikes from ambush and fights with a power and aggression that no other freshwater fish in Asia can match. Around the taimen, grayling and lenok provide supporting sport of the highest order in landscapes that remain almost entirely wild.
The Eg River — Taimen Heartland
The Eg River in Khövsgöl Province drains southward from Lake Khövsgöl, Mongolia's deepest lake, and joins the Selenge River system before eventually reaching Lake Baikal. The Eg is consistently rated among the top five taimen rivers in the world by anglers who have fished both Mongolia and Siberia. The stretch between the confluence with the Uur River and the outflow of Lake Khövsgöl, roughly 170 km of river, produces taimen of 80–120 cm with regularity, and fish over 130 cm are taken each season. Float trips of 6–10 days are the standard approach, sleeping in lightweight camps on the gravel bars and covering 15–20 km of river per day. Large articulated streamers, deer-hair mice, and surface disturbance lures are the principal flies.
The Uur River — Wild Taimen and Grayling Confluence
The Uur joins the Eg near the village of Tsagaan Nuur and is considered by many guides to hold the densest taimen population of any river in Mongolia. The Uur is smaller and faster than the Eg, with more varied structure — deep undercut banks, logjams, and boulder pools that taimen use as ambush lies. On the Uur it is possible to sight-fish for taimen in clear conditions, watching fish of over 100 cm hold in the current and turning to assess the mouse pattern swimming overhead. Grayling fill every pool and riffle between taimen lies, reaching 45 cm and providing constant action on dry flies during mayfly and caddis hatches from June to August.
Lake Khövsgöl — Lenok and Grayling in the Blue Pearl
Lake Khövsgöl, the second-largest lake in Mongolia by volume and one of the oldest lakes on earth at an estimated 2–3 million years, sits at 1,645 m elevation and holds extraordinary water clarity — visibility to over 25 m. The lake does not hold taimen but its tributary streams and the short river connecting it to the Eg are full of Arctic grayling and lenok. Lenok (Brachymystax lenok), a spotted, golden-flanked salmonid that resembles a fat brown trout, reach 50 cm in the lake's inlet streams and respond to both dry flies and small spoons. Boat fishing along the lake's western shore, which is less accessible to vehicles and therefore less pressured, produces the most consistent results.
The Delger Mörön River — Remote Northern Fishing
The Delger Mörön in northern Khövsgöl Province drains a watershed of taiga forest and high steppe that is accessible only by long drives on rough tracks or by horse. This remoteness is the fishing's greatest asset — taimen populations here are as undisturbed as anywhere on earth, and grayling of extraordinary size inhabit every accessible pool. The river's character changes throughout its length: in the upper reaches it runs shallow over gravel beds through open steppe at 1,400–1,600 m elevation; in the lower reaches it deepens and meanders through larch forest, creating the kind of shaded pool structures that large taimen prefer through the hot July afternoons.
The Selenge River — Mongolia's Largest River
The Selenge is Mongolia's longest and largest river, draining the northern watershed before crossing into Russia and emptying into Lake Baikal. Its Mongolian reaches hold substantial taimen populations, particularly in the tributary systems entering from the east — the Orkhon, Chuluut, and Tuul rivers among them. The Selenge itself runs through open steppe near Sükhbaatar and is not wilderness fishing in the same sense as the Eg, but the tributary rivers offer increasingly remote access. The Orkhon River near Karakorum, the ancient Mongol capital, is a convenient and productive option for anglers who want to combine cultural sightseeing with serious grayling and taimen fishing.
The Khovd River — Western Mongolia's Wild Fishery
Western Mongolia's Khovd River drains the Altai Mountains into a series of desert lakes, and its upper reaches above the city of Khovd hold cold, clear water with good stocks of lenok and Siberian grayling. This is a different ecosystem from the northern taiga rivers — drier, more open, the surrounding landscape semi-desert with dramatic red and ochre cliffs — but the fish quality is superb. Taimen are present but less numerous than on the Eg-Uur system. Lenok here are particularly vigorous fighters in the cold, fast water, and grayling of 40 cm are commonplace in the riffle sections between pools.
The Tuul River — Accessible Fishing Near Ulaanbaatar
The Tuul River flows through Ulaanbaatar and continues east through the Gorkhi-Terelj National Park, making it by far the most accessible fishing water in Mongolia. The river within 50 km of the capital has been heavily impacted by human activity, but in the upper reaches of Terelj above the tourist ger camps, the water is still clean and holds grayling of 30–40 cm along with small lenok. Day trips from Ulaanbaatar are practical, and the overnight camps in Terelj make for a comfortable introduction to Mongolian fishing before committing to the logistics of a week-long northern float trip.
The Onon River — Birthplace of Genghis Khan
The Onon River in eastern Mongolia, near the village of Dadal in Khentii Province where Genghis Khan is traditionally believed to have been born, offers superb taimen and grayling fishing in a historically resonant landscape of rolling hills and river meanders. The Onon system is slightly warmer and slower than the northern rivers, which means taimen here are more active during the cooler shoulder seasons of May-June and September-October. A camp on the Onon produces consistent taimen in the 80–110 cm range, and the river's surrounding grassland steppe provides exceptional birdwatching alongside the fishing.
Explore on the map
Mongolia's taimen rivers, mountain grayling streams, and remote steppe lakes occupy a geography that is genuinely difficult to navigate without preparation. The interactive map locates the Eg and Uur river confluence, the shores of Lake Khövsgöl, and the Orkhon valley near Karakorum so you can plan logistics before departure. Every river system described here — from the accessible Tuul near Ulaanbaatar to the wilderness Delger Mörön in the far north — is plotted on Mongolia on the map. Use the map to identify river access points, camp locations, and the nearest roads to some of the world's most extraordinary angling.
