The only protected area on Earth that climbs from tropical forest to the summit of an 8,000-metre peak — wrapped around Mount Makalu, the world's fifth-highest mountain.

From the Arun river valley in the south-east — as low as about 344 m — the land climbs more than 8,000 m to the summit of Makalu. This extraordinary gain makes Makalu Barun the only protected area on Earth that encloses tropical forest and snow-capped peaks within a single boundary, stacking ecosystems from subtropical to nival in one continuous sweep.
Wildlife
The park's vast altitude range supports rich biodiversity, from forest mammals to high-alpine specialists.

The rugged summits within the park include Makalu (8,463 m), the world's fifth-highest mountain, along with Chamlang (7,319 m), Baruntse (7,129 m) and Mera Peak (6,654 m). The park extends about 66 km west to east and 44 km north to south, sharing its northern border with the Qomolangma National Nature Preserve of Tibet and adjoining Sagarmatha National Park to the west.
Visiting
One of Nepal's least-developed and most pristine trekking regions.
A demanding, remote trek through the Arun and Barun valleys to the foot of Makalu.
A glacial valley of waterfalls, forest and alpine meadow, prized for its untouched character.

Wildlife & Ecology
Makalu Barun is one of the most extreme protected landscapes on Earth — it climbs more than 8,000 vertical metres, from subtropical Arun River forest at 344 m to the summit of Makalu (8,463 m, the world's fifth-highest peak). It adjoins Sagarmatha to the west and Tibet's Qomolangma Preserve to the north, and protects roughly 3,128 flowering plants, 88 mammals and 440 birds in a single transboundary block.
Pale, smoke-grey rosetted coat; long thick tail for balance and warmth; fur-cushioned paws for snow. Makalu Barun sits inside one of Nepal's most important snow-leopard landscapes, sharing prey populations with neighbouring Sagarmatha and Tibet's Qomolangma Preserve.
Solitary, crepuscular, vast home ranges across broken alpine terrain.
Himalayan tahr, blue sheep and musk deer; occasional livestock depredation.
Upper Barun Valley and the high terrain toward Makalu Base Camp.
Vulnerable globally. Documented in the wider Makalu–Sagarmatha landscape; no Makalu-Barun-specific population figure has been published with confidence.
The park is part of an unbroken Himalayan protected-area network — Sagarmatha to the west, Qomolangma north and Kanchenjunga east — that gives the snow leopard one of its largest connected ranges anywhere in Nepal.
Almost never directly; sign in the upper Barun valley is the realistic encounter.
A small arboreal mammal with rich reddish-brown fur and a ringed bushy tail; the eastern Nepal subspecies (Ailurus fulgens fulgens) sits in some of the country's best-preserved bamboo–rhododendron forest.
Solitary, arboreal, crepuscular; bamboo specialist that rests in trees through much of the day.
Chiefly bamboo, supplemented with fruit, acorns, eggs and small prey.
Temperate forest of the middle elevations (roughly 2,400–3,600 m) in the Barun and Arun valleys.
Endangered globally; the eastern Nepal protected areas (Makalu Barun and Kanchenjunga) together hold one of the species' largest contiguous habitats.
Habitat fragmentation by grazing, fuelwood collection and trail-side disturbance is the main threat; the park's lower buffer zones are the front line.
Patient trekkers in the middle Barun forest occasionally see one — sightings are rare and almost always brief.
A spectacularly marked, mid-sized cat with the largest canine-to-skull ratio of any living felid. Forest-dwelling and largely arboreal.
Solitary, secretive and largely nocturnal; an expert climber that hunts in the canopy.
Birds, small primates, small mammals; occasionally larger prey such as young deer.
Subtropical and temperate forest of the Arun valley, mostly below 3,000 m.
Vulnerable globally; presence in the park is confirmed but counts are not published.
Effectively impossible to see; the species is known mainly through camera trapping in the wider eastern Himalayan landscape.
Small, primitive deer without antlers; males bear protruding tusk-like canines and a musk gland prized in perfume and traditional medicine.
Shy, solitary, mostly nocturnal/crepuscular; dense understorey specialist.
Grasses, mosses, lichens, leaves and shoots.
Dense forest patches roughly 2,500–4,300 m.
Endangered globally; resident in the park, no Makalu-Barun-specific count published.
Difficult — secretive and forest-bound.
Large, shaggy wild caprid; males 120–140 kg with a striking mane, females 60–80 kg.
Herd-living, diurnal; specialised in precipitous slopes.
Grasses, leaves and shrubs of subalpine and alpine zones.
Steep slopes of the upper Barun valley and around Makalu Base Camp.
Near Threatened globally; present in stable numbers across the upper park.
Upper Barun valley and the slopes around Sherson and Makalu Base Camp.
Around 440 bird species recorded — one of the longest checklists for any Himalayan park, helped by the park's 8,000 m of vertical range and 3,128 flowering plants. Eastern Himalayan endemics and Sino-Himalayan species are particularly well represented.
Around 78 fish species in the Arun and Barun river systems — among the highest fish-diversity figures for any Nepali park, reflecting the Arun's role as a major eastern Himalayan river.
3,128 flowering plant species and 25 of Nepal's 30 documented rhododendron varieties — the densest plant diversity of any Nepali park. The vegetation gradient is unmatched: from tropical valley forest at 344 m to alpine and nival zones above 8,000 m.

Plan Your Visit
Practical context for visitors arriving from another country — how to get here, how long to stay, what you'll actually see, and whether this park fits the trip you have in mind.
Makalu Barun protects the southern slopes of Mount Makalu (8,485 m, the world's fifth-highest peak). It's reached by flying from Kathmandu to Tumlingtar in the east (about 35 minutes), then driving and walking in over several days. There is no road into the park interior and the trek to Makalu Base Camp is one of Nepal's longest and most physically demanding mainstream routes.
It's the wildest of Nepal's well-known high-Himalayan parks — exceptional botanical diversity (one of the few protected areas with a complete tropical-to-arctic vegetation gradient), a real chance of an undisturbed wilderness experience, and a base-camp trek that sees a fraction of Sagarmatha's visitors. The reward is solitude on a 4,800 m base camp.
Late September to early November, and April to early May. Outside these windows, the high camp approaches are subject to snow and bad weather. Monsoon (Jun–Aug) and deep winter (Dec–Feb) are not realistic for a base-camp trek.
Makalu Barun is a long-trek park, not a wildlife-viewing park. The biodiversity is genuinely extraordinary on paper, but most of it is plants, invertebrates and rarely-encountered species — not large mammals you'll spot on the trail.
Season note. Rhododendron belts bloom from late March through April on the approach trails. Post-monsoon (Oct–early Nov) gives the clearest base-camp views; pre-monsoon (Apr–early May) is the second window.
Park entry is collected at the Seduwa checkpost. Bring passport-size photos and small NPR cash.
