Makalu Expedition

What is the Makalu Expedition?

Makalu (8,485 m / 27,838 ft) is the fifth-highest mountain on Earth, rising in the Mahalangur Himal on the Nepal-Tibet border. Known as the "Great Black" for its distinctive dark pyramid shape, it stands in near-total isolation in the remote Barun Valley — one of the least-trafficked high-altitude approaches in Nepal. Its technical demands attract the attention of the world's finest alpinists; the French Couloir and the upper Northeast Ridge offer no straightforward passage to the summit. The first ascent was made on 15 May 1955 by Lionel Terray and Jean Couzy, part of a French expedition led by Jean Franco, in an unprecedented feat where nearly the entire team reached the summit over three consecutive days.

The Northeast Ridge via the Makalu La is the standard route, ascending from Advanced Base Camp at 5,700 m through four high camps before the final steep push through the French Couloir — a 50–60 degree mixed wall of ice and rock in the Death Zone — to the knife-edged summit pyramid. Supplemental oxygen begins at Camp III on the Makalu La (7,400 m). The route is widely considered one of the most technically demanding standard routes among all 8,000-metre peaks, requiring fixed-rope proficiency on steep ice at 50 degrees or higher and documented 7,000m+ experience.

The Makalu Expedition 2027 by AltiPro Adventures is a 60-day full-board Spring expedition departing Kathmandu on 10 April 2027. A maximum of 8 climbers is accepted, with a guaranteed 1:1 Climbing Sherpa ratio, five oxygen cylinders per climber, two structured acclimatization rotations, and an Expedition Doctor at Base Camp for the full season.

Why Climb Makalu?

Northeast Ridge Route — via the Makalu La (8,485m)

The Northeast Ridge via the Makalu La is the standard and normal route on Makalu, considered far more technically challenging than the conventional routes on Everest. Starting from Advanced Base Camp at 5,700 m, the route traverses four high camps before the final steep climb to the summit pyramid. The route is favored by the world's finest climbers for its technical challenge and the isolation of its upper elevations.

Acclimatization Rotations

Two structured rotations build progressive exposure on the Chago Glacier and upper Northeast Ridge before the summit bid. The 10-day approach trek through the Barun Valley — including rest and acclimatization days at Khongma La and Shersong — provides the foundation before rotations begin from Advanced Base Camp at 5,700 m.

How Difficult is the Makalu Expedition?

Makalu is graded Extreme / Technical and is widely considered one of the most technically demanding 8,000-metre objectives in the world. While Everest is often more crowded, Makalu requires a higher level of technical proficiency to navigate the French Couloir — a steep 50–60 degree mixed gully of ice and rock in the Death Zone. The mountain's isolation in the Barun Valley means that logistical support and rescue timing are critical factors. AltiPro requires a minimum of one successful 7,000m+ technical summit, with documented experience on fixed ropes on steep ice at 50 degrees or higher.

Makalu is not recommended as a first 8,000-metre peak. Climbers must possess documented experience with fixed-rope handling on steep ice (50 degrees or higher) and be proficient with crampons, ice axes, jumars, and descenders. The primary risks include altitude sickness, technical falls on the French Couloir, extreme high-velocity winds, and the logistical challenges of the remote Barun Valley.

Best Season for the Makalu Expedition

The Spring season (April–May) is the best and primary window for the Makalu Expedition. During late April, the Himalayan jet stream shifts, opening more stable summit windows. AltiPro specifically times summit attempts for mid-to-late May to capitalise on favorable pre-monsoon weather patterns on the Northeast Ridge.

Spring (April–May): The prime window. April covers the approach trek through the Barun Valley and Base Camp establishment with early acclimatization rotations. Mid-to-late May provides the most reliable summit windows as the jet stream moves north of the Mahalangur Himal.
