Helambu Trek

The Helambu trek is an 8-day loop through the hill villages north-east of Kathmandu, home of the Yolmo (Hyolmo) people, with a high point at Tharepati at about 3,650 m. It starts with a short drive to Sundarijal at the edge of the Kathmandu Valley, climbs through Shivapuri Nagarjun National Park to Chisapani, follows the ridge to Kutumsang and Tharepati, descends to Melamchigaon and Tarke Ghyang, and ends at Sermathang and Melamchi Bazaar before the drive back. The route covers about 90 km on foot with about 6,700 m of climbing and uses simple lodges every night, so no camping is needed. It is a moderate trek with steep stretches and long days, and no restricted-area permit is needed, only the national park permits. March to May and October to November are the best months, and winter is possible at low altitude. It suits first-time trekkers who want a short, cultural walk.

What the trek is like

From Sundarijal, the trail climbs steep stone steps beside a water pipeline into oak and rhododendron forest, then follows the Shivapuri ridge to Chisapani, a ridge village with long views of the Himalaya on clear mornings. Beyond Gul Bhanjyang and Kutumsang, the path climbs into fir and rhododendron forest to the Tharepati ridge, with views of Langtang Lirung and the Jugal range. It then descends to the Yolmo villages, with stone houses, mani walls and monasteries, and drops through apple orchards and terraces to Sermathang and Melamchi Bazaar. Most of the walk is on footpaths, with a few road crossings.

Highlights

• Tharepati, a high ridge with panoramic views of Langtang Lirung and the Jugal range
• Melamchigaon and Tarke Ghyang, Yolmo villages with gompas and mani walls
• Sermathang, known for its monastery and apple orchards
• Forest walks through Shivapuri Nagarjun National Park
• Short access from Kathmandu, with no flights

Permits and rules

You need the Shivapuri Nagarjun National Park entry permit at Sundarijal, the Langtang National Park entry permit for the higher section from Kutumsang on, and a TIMS card where the local office asks for it. Helambu is not a restricted area. The Nepal Tourism Board April 2023 rule requires foreign trekkers to use a licensed guide in national parks and conservation areas, and 2026 operator reports say checkpoints enforce it in Annapurna (ACAP), Langtang (the strictest) and most other parks, but not in Khumbu, where the municipality opted out (checked 19 October 2026). See the guide rule by region. Fees differ for foreigners, SAARC nationals and Nepalis, so ask for current amounts and check them with the park offices or the Department of National Parks and Wildlife Conservation.

Best season

March to May and October to November are the best months, with clear views in autumn and rhododendron in spring. Winter is cold but clear and quieter, with snow above Kutumsang. The monsoon has leeches, rain and landslides, and the 2021 floods on the Melamchi river damaged the valley, so check road conditions at the end of the trek.

Altitude

The highest point is Tharepati at about 3,650 m, and most of the trek stays between 1,400 m and 2,600 m. The climb from Kutumsang (about 2,470 m) to Tharepati is steady, and most people do not feel altitude sickness, but sleep at Melamchigaon or Tarke Ghyang if you have a headache. Never ascend with symptoms, and descend if they worsen.

Getting there and away

Take a bus or jeep from Kathmandu to Sundarijal, about an hour, and walk from there. At the end, drive from Melamchi Bazaar to Kathmandu in about 3 to 4 hours. Some trekkers use a jeep for part of the first or last section, and jeeps also serve Chisapani and Kutumsang in places. Landslides can close the Melamchi road in the monsoon.

Lodges, food and costs

Lodges at Chisapani, Kutumsang, Tharepati, Melamchigaon, Tarke Ghyang and Sermathang offer dal bhat, noodles, eggs and tea in simple rooms with blankets. Facilities are basic, and prices rise with altitude. Bring cash for the whole trek, because there are no machines beyond Sundarijal and Melamchi.

Packing list

Broken-in boots, waterproof layers, a warm jacket, a sleeping bag rated to about minus 5 C, hat and gloves, sunglasses, sun cream, trekking poles, a headlamp, water purification and a first-aid kit. In winter and early spring add a down jacket and in summer leech socks.

Who this trek suits and how to prepare

The trek suits first-time trekkers and anyone with limited time. The days are long at 6 to 9 hours, with steep ups and downs, so prepare with hill walks, stair training and some days with a loaded pack. No technical skills are needed.

The plan at a glance

Day 1 walks from Sundarijal to Chisapani and day 2 to Kutumsang. Day 3 climbs to Tharepati and day 4 descends to Melamchigaon. Day 5 walks to Tarke Ghyang and day 6 to Sermathang. Day 7 descends to Melamchi Bazaar and day 8 drives to Kathmandu.

Extensions

From Tharepati you can continue over the Laurebina La, at about 4,600 m, to Gosaikunda and Dhunche, a trek of three to four more days that joins Langtang. You can also add a day at Tarke Ghyang or Melamchigaon, or walk from Sermathang to Melamchi Bazaar by the lower trail.

Practical tips from the trail

• Walking times in the day plan are estimates from distance and climb, checked against operator itineraries; real times differ with pace, load and weather.
• Take rain gear even in autumn, since afternoon cloud is common.
• Start early on the long days to Kutumsang and Tharepati.
• Carry cash and small notes, as villages have no machines.
• Respect monasteries and walk clockwise around mani walls.
• Check the weather before leaving Kutumsang, because snow can block the ridge in winter.

Responsible trekking

Take rubbish out, use filtered water, buy from local families and respect Yolmo customs. Do not give sweets or money to children.
