Bayan-Olgii (Баян-Өлгий аймаг)· Алтай Таван Богд байгалийн цогцолборт газар

Altai Tavan Bogd National Park

Altai Tavan Bogd protects Mongolia's highest corner, a 6,362 km2 block of glaciated peaks, cold blue lakes and Kazakh and Tuvan summer pastures against the Russian and Chinese borders. Its centrepiece is the Tavan Bogd, the 'Five Saints' massif, topped by Khuiten Peak on the Mongolia-China boundary, with the Potanin Glacier - Mongolia's longest at about 14 km - running below it. South of the peaks the freshwater lakes Khoton, Khurgan and Dayan sit in wide valleys used by herding families, and the Tsagaan Salaa valley holds thousands of Bronze Age rock carvings inscribed by UNESCO. Nothing here is quick: reaching the base camp means a long day on dirt from Olgii, and the mountain itself needs guides, permits and crampons.

From Ulaanbaatar: 1,620 km
Drive time: 2-3 days to Olgii (about 21 hours of driving), then 6-9 hours more on dirt from Olgii to the park
Typical stay: 6-9 nights in the region, of which 3-5 in the park; 10-14 if climbing
Best months: Jun–Sep

Highlights

Tavan Bogd base camp and the viewpoint over the Potanin Glacier, about 14 km long, the longest in Mongolia
Khuiten Peak, Mongolia's highest summit, on the border with China and close to the Russia-Mongolia-China tripoint
The Mongolian Altai petroglyphs, over 10,000 carvings along roughly 15 km of river valley, a UNESCO World Heritage site
Khoton and Khurgan lakes, linked by a short 2 km channel, with larch forest and herder camps on the shores
Dayan Lake, an Important Bird Area since 2009, frozen from October to June
Kazakh and Tuvan summer camps in the valleys, where eagle hunters keep their birds out of season
Malchin Peak, the one summit in the massif usually climbed without technical gear
Bronze Age burial mounds, deer stones and Turkic stone figures scattered across the valleys

Season notes

The park is realistically open from mid-June to mid-September. Snow blocks the high passes into the base-camp valley until June and returns from late September. July and August are the warmest and the only sensible window for the glacier and the peaks; August sees the most stable weather for climbing. Dayan Lake is frozen from October to June. Snow can fall in any summer month at altitude, and afternoon storms are common on the massif.

From Ulaanbaatar

Mostly paved as far as Olgii, but it is the longest road journey in the country; routing engines give about 1,619 km. Beyond Olgii, Wikivoyage notes there are effectively no paved roads outside the city, and the tracks to Tsengel, the lakes and the Tavan Bogd base area are dirt, rough and cross rivers. A high-clearance 4x4 with a local driver is not optional.

By air
Fly Ulaanbaatar-Olgii; Aero Mongolia and other carriers serve Olgii Airport (ULG) several days a week with an expanded summer schedule, and Wikivoyage warns that summer flights sell out, so book early. Olgii also has irregular links to Khovd, Ulaangom, Murun and occasionally Almaty. The daily bus from Ulaanbaatar costs 80,000 MNT and takes at least 30 hours (36-48 hours is commonly quoted).

Where to stay

Ger camps around Olgii and in the park valleys, open roughly May-October; Wikivoyage lists about USD 20 single, USD 10 per person double, and USD 5-7 per person for three or more beds, with higher prices in festival week (retrieved September 2026)
Hotels in Olgii for the nights either side: simple rooms about 30,000 MNT, semi-deluxe 45,000 MNT, deluxe 60,000 MNT (Wikivoyage, retrieved September 2026)
Homestays in Kazakh and Tuvan family gers in the lakes area, usually arranged through an operator
Own tent at Tavan Bogd base camp; there is no built accommodation at the glacier

Be aware

Altitude: the base camp and passes are high enough for headaches and breathlessness, and Khuiten is a glaciated 4,300 m-plus peak needing rope, crampons and a guide

Two border permits plus the park permit, all arranged in Olgii; turning up at the gate without them wastes days

Outside Olgii there is effectively nowhere to buy food or fuel, and Wikivoyage advises filtering river water because of livestock grazing

Extremely long approach - the longest overland trip in Mongolia - and rough dirt tracks with river crossings beyond Olgii

Weather turns fast; snow, hail and hard frost are possible at the massif in July and August

Friday is a dry day in Olgii with no legal alcohol sales, and public drunkenness draws police attention

Mobile coverage is absent for most of the park

Petroglyph sites are unfenced and fragile: do not walk on, chalk or wet the carvings

Fees

Altai Tavan Bogd National Park permit: 3,000 MNT per person, bought at the visitor centre on the south-east corner of the main square in Olgii (Wikivoyage, retrieved September 2026)
Border-zone permits are required in addition to the park permit because the park runs along the Chinese and Russian frontiers; Wikivoyage describes obtaining the Chinese-side permit at the army barracks and the Russian-side permit in Tsagaannuur village. Allow time in Olgii for this and carry your passport.

Golden Eagle traditional and folk festival competition part. Western Mongolia, Bayan Ulgii province

Bayan-Olgii Kazakh eagle hunters and the eagle festivals

Bayan-Olgii · 1,620 km

Bayan-Olgii is Mongolia's only Kazakh-majority province, and the practice that defines it is hunting foxes and hares from horseback with a trained golden eagle. Around 250 active eagle hunters are counted in the province, and two autumn festivals - a smaller one at Sagsai in September and the main Golden Eagle Festival near Olgii in early October - bring them together to be judged on how their birds fly to the fist, how they take a lure, and on their costume and kit. Around the festivals the province is worth days in its own right: mosques and bazaars in Olgii, Kazakh embroidery and felt-work, and family gers with an eagle on a block outside. The real hunting season, though, runs through the winter, from about mid-October to the end of February.

Best months: Sep–Oct

Uvs Lake (Uvs Nuur) and its UNESCO basin

Uvs · 1,370 km

Uvs Nuur is Mongolia's largest lake by surface area, a shallow, intensely salty sheet of water at 759 m that has no outlet and sits at the centre of a transboundary basin shared with Russia's Tuva. The basin was inscribed on the UNESCO World Heritage List in 2003 and added to the Ramsar list in 2004, because within one catchment it holds desert dunes, salt marsh, steppe, taiga, tundra and glaciated mountains, and is one of the last remnants of the mammoth steppe. Practically, visitors base themselves in Ulaangom and drive out to the shore for birdlife and the extraordinary emptiness, then head south-west into the Kharkhiraa and Turgen mountains for walking and horse trekking. It is one of the least visited corners of Mongolia, and also one of the harshest: the basin has recorded both -58 C and +47 C.

Best months: Jun–Sep
