Best Time to Lumba Sumba Pass Trek
The Lumba Sumba Pass Trek is a challenging and rewarding journey that connects the Kanchenjunga Conservation Area, home to the world’s third-highest peak, Kanchenjunga (8,598 meters), with the Makalu Barun National Park, which houses the fifth-highest peak, Makalu (8,485 meters). First explored in 2012, this trek offers an immersive wilderness experience along the Great Himalayan Trail.
Spanning approximately 20 days, the trek begins in subtropical regions and ascends to alpine terrains, presenting trekkers with diverse challenges, including traversing high mountain passes, navigating untamed environments, and exploring isolated valleys. The route is rich in biodiversity, with opportunities to encounter rare wildlife such as snow leopards and red pandas.
A highlight of the journey is the crossing of the Lumba Sumba Pass at an elevation of 5,160 meters, offering breathtaking landscapes and topographical diversity. The trek also features the Nanga La Pass and follows the Tamor and Arun river systems, major tributaries of the Sapta Koshi River. Trekkers will traverse alpine grasslands, rocky outcrops, dense temperate and subtropical forests, and low river valleys.
Beyond its natural allure, the trek provides cultural insights into the lives of various ethnic groups, including the Limbus, Rai, Sherpas, Magars, and Tamang. Along the way, trekkers will encounter monasteries, chortens, temples, prayer flags, and walls, enriching the journey with spiritual significance.
The optimal times for the Lumba Sumba Pass Trek are during the spring (March to May) and autumn (September to November) seasons. These periods offer stable weather conditions, clear skies, and moderate temperatures, enhancing the trekking experience. During spring, the trails are adorned with blooming rhododendrons and lush greenery, while autumn provides crisp air and unobstructed mountain vistas.
Embarking on the Lumba Sumba Pass Trek promises an unparalleled adventure, combining the thrill of high-altitude trekking with the serenity of Nepal’s diverse ecosystems and rich cultural tapestry.
Accommodation During the Lumba Sumba Pass Trek
The Lumba Sumba Pass Trek is primarily a camping trek due to the remoteness of the region. Along the trail, trekkers stay in tents, with a dedicated kitchen crew preparing meals. The food includes a mix of rice, lentils, vegetables, noodles, pasta, dumplings, and local bread, ensuring a balanced diet for high-altitude trekking. While some basic tea houses may be available in certain villages, they offer minimal facilities, making camping the primary accommodation option.
Since the trek passes through isolated areas, carrying extra snacks like energy bars, nuts, and dried fruits is recommended. In lower regions, fresh vegetables may be available, but as the altitude increases, food supplies become more limited. Drinking water is mainly sourced from natural streams, so using water purification tablets or filters is necessary. The overall experience provides a raw and immersive adventure into Nepal’s wilderness, combining challenging terrain with breathtaking landscapes.
