Geography of the Manaslu Region

The Manaslu region, situated in the west-central part of Nepal, is renowned for its diverse landscapes, rich cultural heritage, and the towering peak of Mount Manaslu, the eighth-highest mountain in the world at 8,163 meters (26,781 feet). The region’s geography is marked by dramatic elevation changes, diverse ecosystems, and a blend of natural and cultural attractions.

Elevation and Topography of Manaslu Circuit Trek

The Manaslu region features a wide range of elevations, starting from around 600 meters (1,968 feet) in the lowland valleys to the summit of Mount Manaslu at 8,163 meters (26,781 feet). This significant variation in altitude creates a diverse range of climates and ecosystems within a relatively small geographical area.

The Manaslu region’s geography begins in the lowland valleys, such as Machha Khola at 800 meters (2,624 feet), where trekkers encounter a subtropical climate. These lower regions are characterized by lush green forests, terraced fields, and vibrant rivers, providing a rich and fertile landscape that supports a variety of plant and animal life.

Temperatures in these valleys range from 15°C to 30°C (59°F to 86°F) during the warmer months and drop to 10°C to 15°C (50°F to 59°F) during the cooler months, making for a relatively mild and comfortable climate.

As the trek ascends to mid-altitudes, through villages like Jagat at 1,300 meters (4,265 feet) and Deng at 1,860 meters (6,102 feet), the terrain transitions into more temperate zones. This elevation is marked by mixed forests of pine and oak, as well as agricultural land where local communities grow crops and raise livestock.

Temperatures here are cooler, ranging from 10°C to 25°C (50°F to 77°F) in the warmer months and dropping to 5°C to 10°C (41°F to 50°F) during the cooler months. The climate is less humid than the lowland valleys, making it ideal for farming and habitation.

Further up, at high altitudes in places like Samagaon at 3,530 meters (11,581 feet) and Samdo at 3,875 meters (12,713 feet), the landscape transforms into an alpine environment. This elevation features coniferous forests, open meadows, and high-altitude pastures where yak herding is common.

Temperatures in these high-altitude areas can range from -6°C to 10°C (21°F to 50°F) during the warmer months and drop significantly to -15°C to 5°C (5°F to 41°F) during the colder months.

Near the top, in the glacial zones around Manaslu Base Camp at 4,800 meters (15,748 feet) and Larke Pass at 5,175 meters (16,978 feet), the terrain is dominated by glaciers, snowfields, and rugged mountainous landscapes. Here, temperatures can range from -10°C to 10°C (14°F to 50°F) during the warmer months and plummet to -20°C (-4°F) or lower during the colder months, offering a breathtaking and dramatic contrast to the lower regions.

Rivers and Glacial Lakes of Manaslu Circuit

The Manaslu region is distinguished by its significant rivers and high-altitude glacial lakes, which play crucial roles in shaping its landscape and supporting local ecosystems.
