The Lumba Sumba Pass Trek, offered by Hairy Yak Adventures, is an 18-day adventure through the remote eastern Himalayas of Nepal, connecting the Kanchenjunga Conservation Area and Makalu Barun National Park. Priced at $2,800 per person, this challenging trek is perfect for experienced trekkers seeking solitude, breathtaking landscapes, and cultural immersion. The highlight is crossing the Lumba Sumba Pass (5,177m), offering panoramic views of Kanchenjunga (8,586m), Makalu (8,485m), and distant peaks like Everest and Lhotse.

This trek, introduced in 2012 by the Trekking Agencies Association of Nepal (TAAN), traverses pristine landscapes, from subtropical forests and terraced fields to alpine meadows and glacial moraines. Trekkers pass through vibrant villages inhabited by ethnic groups like Limbu, Sherpa, Rai, Gurung, and Tamang, with opportunities to visit ancient monasteries like Dekichholing in Olangchung Gola. The route is a biodiversity hotspot, home to rare wildlife such as snow leopards, red pandas, and Himalayan tahr, alongside vibrant rhododendron and orchid forests. Unlike more popular treks, Lumba Sumba remains uncrowded, offering tranquility and an authentic Himalayan experience.
The journey begins with a 50-minute flight from Kathmandu to Tumlingtar, followed by a 4–5-hour jeep ride to Num, the trek’s starting point. The trail includes challenging ascents, such as Shipton La Pass (4,200m), and visits to remote settlements like Seduwa, Tashigaon, and Olangchung Gola. Trekkers stay in teahouses and tents, enjoying local cuisine like dal bhat and momos. With a maximum altitude of 5,177m, the trek demands excellent physical fitness and mental resilience, supported by acclimatization days to ensure safety. This off-the-beaten-path adventure promises stunning sunrise views, cultural encounters, and a profound connection with Nepal’s untouched wilderness.

Focus on cardiovascular fitness and strength for steep ascents/descents and long trekking days.
Practice hiking with a loaded backpack to prepare for carrying gear.
Proper Gear
High-quality mountaineering boots, crampons, and trekking poles for rugged and snowy trails.
Layered clothing (moisture-wicking base layers, insulated jackets, waterproof outerwear).
Sleeping bag, tent, and cooking equipment for camping, as teahouses are limited.
Sunglasses, sunscreen, and a hat for UV protection at high altitudes.
Pack Light
Carry only essentials to reduce weight, as porters or yaks handle main luggage.
Prioritize lightweight, multi-use items (e.g., quick-dry clothing, compact toiletries).

Hydration and Altitude
Drink 3-4 liters of water daily; carry a reusable bottle and purification tablets for local water sources.

Carry Diamox or similar medications as a preventive measure for altitude sickness.
Acclimatization
Follow itineraries with rest days (e.g., at Olangchung Gola) to adjust to altitudes above 3,000m.
Ascend gradually, avoiding rapid gains above 4,000m to reduce altitude sickness risk.
Consult guides immediately if symptoms of acute mountain sickness appear.
Cash and Connectivity
Carry sufficient Nepalese rupees in cash, as ATMs and card payments are unavailable in remote areas.
Expect limited mobile connectivity beyond Lelep; satellite phones are recommended for emergencies.

Pack biodegradable soap, toothpaste, and wet wipes for hygiene in remote areas.
Bring hand sanitizer and a quick-dry towel for shared or basic facilities.
